non ferrous metals uses

A: non-ferrous metals in copper is the earliest human use of metal materials. Modern, non-ferrous metals
Color metal and its alloys have become the machinery manufacturing, construction, electronics, aerospace, nuclear energy and other essential areas of structural materials and functional materials.
B: practical applications, usually non-ferrous metals are divided into five categories:
1 light metal. Density less than 4500 kg / cubic meter, such as aluminum, magnesium, potassium, sodium, calcium, strontium, barium, etc.
 2 heavy metals. Density greater than 4500 kg / m 3, such as copper, nickel, cobalt, lead, zinc, tin, antimony, bismuth, cadmium, mercury, etc.
3 precious metals. Expensive than commonly used metal prices, low crustal abundance, purification difficulties, such as gold, silver and platinum group metals.
4 semi-metal. Nature of the price between the metal and nonmetal, such as silicon, selenium, tellurium, arsenic, boron and so on.
5 rare metals. Including the rare light metal, such as lithium, rubidium, cesium, etc.;
Rare and refractory metals such as titanium, zirconium, molybdenum, tungsten, etc.;
Rare and dispersed metals such as gallium, indium, germanium, thallium, etc.;
Rare earth metals such as scandium, yttrium, lanthanide metal;

Titanium uses

The strength of the titanium, pure titanium tensile strength maximum of 180 kg/was. Some of the strength of steel, but higher than the titanium alloy titanium than intensity (tensile strength and density than) but more than the high quality of steel. Titanium alloy have good heat resistance strength, low temperature toughness and fracture toughness, so many used for aircraft engine parts and the rockets and missiles structure. Titanium alloy also for fuel and oxidizer store box and high pressure vessel. Now already useful titanium alloy manufacture automatic rifle, mortars a board and no kicks back cannon of tube. In the oil industry for all kinds of containers, the main reactor, heat exchangers, distillation, pipe, pumps and valves, etc. Titanium can be used as electrode and power stations in the condenser and environmental pollution control device. Nickel titanium shape memory alloy in instrumentation has widely used. In medical treatment, titanium can make artificial bones and all kinds of instruments. Titanium or steelmaking as deoxidizer and stainless steel and alloy steel group yuan. Titanium dioxide pigments and paint is a good raw material. Titanium carbide, carbon (hydrogen) the titanium is new hard alloy material. Nitriding titanium color to gold, in adornment respect wide application.
Titanium and titanium alloy are widely used for the aviation industry, have "space as metal"; In addition, in the shipbuilding industry, chemical industry, machinery parts manufacturing, telecommunications equipment, hard alloy has day by day the widespread application.
In addition, the titanium alloy also have very good compatibility with the human body, so the titanium alloy can do artificial bone.
Titanium corrosion resistance is a used in atomic energy industry and high temperature under high pressure used for corrosion resistance of chemical materials, but in a solution of its lively after sodium.
So, in hydrogen oxide solution to live wave of nitric acid solution will be found, zirconium titanium the nitric acid zirconium out the door.
Can see in the photo, obviously, it is layered nitric acid zirconium, below is hydrogen oxide.
We know, the density of the titanium oxide hydrogen zirconium, but still less than nitric acid can keep a clear separation, and stay in the upper level, zirconium nitric acid is proof that titanium corrosion resistance.
According to the experiment, the titanium in 20 to 50 annual average won't be corrosion.

solar energy advantages and disadvantages

dvantages:1. The universality.
The light of the sun in the area of the earth's most corner, spread to just incident Angle caused by the different light have different, but at least will not be a few countries or regions, cause unnecessary monopoly energy crisis.
2. Permanent.
The solar energy very large, scientists calculated that at least six million years, the time limit for humans, this time it is infinite.
3. No pollution.
Now use most minerals, the growth of the energy problem to be but waste disposal, the object is eternal, the more energy depletion, produce pollution is also relatively increase, solar energy, no risk and pollution. In the human and nature under the principle of peaceful co-existence, use the solar energy does not hurt, and, in the case of equipment and gas use proper, device into expenses required is few, and after a year can be born at least ten 17 power of electric power. Kw Coal, oil and other fossil fuels the harmful gas and waste residue, while the use of solar energy will not bring pollution, not from any adverse impact on the environment of material, is a kind of clean energy. Of course, the use of solar energy, because after the full use of solar energy, the result will be that the environmental temperature increased slightly, but this kind of temperature rise, not the adverse impact on the environment.
4. Solar is a human can use the most abundant energy.
According to estimates that in the past one billion one hundred million years long, the sun only consumes 2% of the energy it itself, billions of years the sun in the future will not happen obvious change, so the sun can be used as a human permanent energy, inexhaustible, an inexhaustible. It to the ground illuminate 15 minutes of energy, enough for a year. Use around the world
5. The solar energy security can be sex.
Nuclear power will have the danger of nuclear leakage, once the nuclear leaked will cause great ecological crisis, and the solar energy absolutely no this kind of situation, it is very reliable.

Faults:
1. Poor stability.
By night and day, and the solar energy climate impact, reach highly constant. Because this must have storage device, it not only increased technical difficulties, also make the cost increase. At present although has made DuoZhong storage systems, but always insufficient ideal, specific application also have certain difficulty.
2. The high cost of device.
Although the whole ground to very large solar energy, but this kind of energy very scattered, as energy, its density is too low. Therefore, the use of solar energy device must have quite a large area, to collect enough power. But, large area, cost will be high. Only when the value of the surface energy device unit cost quite cheap, can use this cost-effective solar energy device.
3. Someone for solar the pollution problem of the proposed "visual pollution."
Which means huge solar energy collector cause visual pollution, have this to say.

Earth is a group of both electric, magnetic, optical, and biological and other properties of new functional materials, the information technology, biotechnology, energy technology and other high-tech fields and important basis for national defense materials, but also on the transformation of some traditional industries such as agriculture, chemicals, building materials plays an important role. RE versatile, you can use a wide range of rare earth functional materials, are forming a large-scale high-tech industry group, has a very broad market prospects and a very important strategic significance. "Industrial vitamin" reputation.
China is truly the world's largest rare earth resources in the country, has been proven about 65.88 million tons of rare earth resources. China's rare earth resources is not only abundant, but also with complete minerals and rare earth elements, rare earth ore grade and a reasonable distribution of points and other advantages, the development of rare earth industry in China has laid a solid foundation. China's rare earth resources in very favorable conditions for mineralization, deposit type is complete, wide distribution and a relatively concentrated.

what are nanomaterials

nanomaterials are refers to the three dimensional space scale at least one d in the nanometer range (1-100 nm) material, it is by size between atoms, molecules and macroscopic system of the nanoparticles between composed of a new generation of materials. Because of its component unit of the scale of the small, interface take considerable composition. Therefore, nanometer material has DuoZhong characteristics, leading to the nanoparticles by a system composed of different from the usual appeared chunks of macro material system of the many extraordinary properties. Nano system so that people familiar with nature and to enter into a new level, it is contact atoms, molecules and macroscopic system of the intermediate links, and the people in the past is never explored new areas, in fact the nano of particles materials to macroscopic system evolution process, on the structure change of ordered degree, in state of the balance of the nature of the nature, make the system makes a big difference, of nanometer materials research will keep people from the micro to macro more familiar with the transition.
