Uses: Suitable for steel making, casting and other uses for the production of boron added agent.Application: Mainly used in structural alloy steel, spring steel, heat resistant steel, stainless steel etc. B can enhance toughness, wear resistance in cast iron.Chemical properties: a more lively, is tasteless, odorless, in the air and stable at room temperature and heated to 300 ℃ oxidized reach 700 ℃ that is burning. The combustion flame red, trace boron gasification flame is green. Elemental boron insoluble in water, hydrochloric acid, ethanol and ether, sulfuric acid, nitric acid and molten metal. A density of 1.73. At high temperatures, the boron can interact with oxygen, nitrogen, sulfur, halogen, and carbon. Boron compound directly with many metals to form metal compound, an organic compound can also be used in the reaction of an organic boride.
