Boron powder

Boron powder amorphous boron powder First, the nature of amorphous boron powder is a black or brown amorphous powder, melting point 2150 ℃, boiling point 3680 ℃, the chemical nature of lively, stable in air and at room temperature, heated to 300 ℃, oxidized, that is on fire reaches 700 ℃, trace boron gasification flame was green. Interaction can be generated at high temperatures with oxygen, nitrogen, sulfur, halogens and various carbon compounds, but also compounds with many metals directly generate metal boride, reacts with an organic compound can be an organic boride. Second, the quality of purity: B≥99% purity: B 94 ~ 95% purity: B 88 ~ 90% Third, use: 1, reactor neutron absorber and neutron counter 2, pharmaceuticals, ceramics industry and organic synthesis catalyst 3, the electronics industry ignitron ignition electrode 4, high-energy solid fuel rocket boosters 5, the synthesis of various high-purity boron compound 6 car's airbag initiators 7, 8 special alloy steel smelting, production of boron fiber raw materials 9, molten copper gas scavenger 10, 11 fireworks industry, molten copper gas scavengers
