Rome, Babylonhad

In recent years there are a lot of materials of fiber of pine forest of the countries through which gradually get into area of the sports goods, such as golf clubs, tennis rackets, can improve force and rigidity of these deliveries. In the industry use of hardness of pine forest can make a set of drills, the devices of an ultratsentrifugirovaniye made, using pine forest fibers, highly elastic module, low thermal properties of expansion, superconductivity generators, just as high-speed, the high force rotating the mechanical equipment, etc. Products of an isotope of a powder and pine forest of pine forest of an element - nuclear protection of important materials. With establishment and development of a nuclear power plant in China, its requirement is very impressive.

International requirement of products, such as automobile capsule of safety amorphous demand for a powder of pine forest about 15 t. Transparent materials, such as pine forest transformers a ferrosilitsiya and an electric steel sheet material of alternative which can be used for refractories, nouses of the rocket, materials of high temperature. A pine forest oxide - the main raw materials to make a pine forest powder, metal бориды and борат, mainly used in electronics, the semiconductor, бориде, iron and other areas. Pine forest, some kind of chemical elements. About 200 to N э, ancientEgypt, Rome, Babylonhad used to the drill production glass and the welded gold. In 1808Franceboron potassium of use of the chemist restore the received element pine forest of boric acid. The content of pine forest in a terrestrial crust makes 0.001 %
