Pine forest - a nonmetallic

Natural pine forest has two isotopes: pine forest 10 and pine forest 11, pine forest 10 is the most important. Pine forest - a nonmetallic element. Element pine forest has amorphous powder of pine forest and transparent pine forest two look. Former brownish-black to smoky gunpowder; the last was coaly to silver-gray, remarkable metal shine, is close to hardness of diamond, but there is very high resistance, electric increases in conductivity with the increasing temperature. Amorphous powder density of pine forest - 2.3 gcm 3 25-27 C; transparent element density of pine forest - 2.31 gcm 3. Pine forest 2300C melting point, boiling point 2550C. Pine forest has an extensive application. Pine forest in a combination to plastic or aluminum - an effective material of a protection of a neutron; the borsoderzhashchy steel used in the reactor as a rod of control; pine forest fibers for production of a composite material and so on. Pine forest is rather steady at room temperature, even long-term boiling in hydrochloric acid or hydrofluoric acid does not work. Pine forest can unite with elements of group of halogen to create pine forest halide. Pine forest in 600 1000C can react with sulfur, tin, phosphorus, arsenic; in 1000 to 1400C, react with nitrogen, carbon, silicon effects, under pine forest of high temperature also react with many metals and metal oxides, created metal.

These structures in general with high hardness, resistance to thaw, high electric conductivity and chemically inert substances, it is frequent with special properties. 1702 French doctors at first from the drills, made of the boric acid called salt of calm. In 1741 the French chemist specified that the drill reacts with sulfuric acid not, only receive boric acid, but also and receive sodium. In 1789 scientists included group of boric acid in a table of elements. 1808 British chemists and potassium of use of the chemist of France to restore boric acid received pine forest. The amorphous powder of pine forest at the room temperature oxidized in air slowly, in about 800, can be direct dismissal. Pine forest with hydrochloric acid or hydrofluoric acid, even thus that long-term boiling could not react. It can be slowly destroyed and oxidized by a mix of the hot concentrated nitric bichromate of acid and sodium and sulfuric acid. Peroxide of hydrogen and persulfate ammonium also can be the slow oxidized transparent pine forest. These reactants react with amorphous pine forest, cruelly. Evtektika with an alkaline mix of carbonates and the metal hydroxides, all various forms of pine forest are completely oxidized. Chlorine, bromine, fluorine reacts with pine forest to create the corresponding halide of pine forest. Pine forest intensive reaction in 600 also is gray to create sulfurized a pine forest mix. Pine forest in nitrogen or the gas of the ammonia which has been heated up to aforementioned 1000, can create nitride of pine forest above 1800-2000 pine forests, and hydrogen, still react, pine forest and silicon is higher 2000 can to react to make silicon борида. At high temperatures pine forest can react with many a metal powder and metal oxides to make metal.
