Boron is found in 0.001% of the Earth's crust. Boron is a black or silver-gray solid. Crystal boron is black, second only to diamond hardness and brittle texture. Boron is named Boron, which comes from the Arabic word for flux. That means the ancient Arabs already knew that borax could melt metal oxides and was used as a flux in welding. Boron has the greatest volume of heat, second only to beryllium by weight. Slightly soluble in nitric acid, insoluble in water. Boron powder is a black or dark brown powder that can react with fluorine at room temperature, not by hydrofluoric acid and hydrofluoric acid solution corrosion. Boron powder is insoluble in water, in boiling nitric and sulfuric acids, and in most molten metals such as copper, iron, manganese, aluminum, and calcium. It is widely used in metallurgy, electronics, medicine, ceramics, nuclear, chemical, and other fields. Boron powder has a much higher calorific value than magnesium powder, aluminum powder, and lithium powder. Boron has a high cumulative and mass calorific value, so Boron is also used in comparison with traditional oxyhydrogen fuel propellants. The combustion of metal fuel can release more energy. So magnesium and aluminum lithium is often used as fuel in solid propellants, which can improve the combustion and energy performance of engine flame temperature and specific impulse; boron powder relative to magnesium powder, aluminum powder, and lithium powder this metal fuel calorific value is much higher, Boron has high calorific value and high mass calorific value, so Boron is also used in spacecraft and other high-energy fuel. Boron powder is also used in metal smelting, electronics, ceramics, chemical, and nuclear industries: spacecraft and additional high-energy energy. Insoluble in water but soluble in hydrochloric acid ethanol and ether, and soluble in cold concentrated alkali solution, when dissolved, will decompose hydrogen; boron powder is oxidized by concentrated nitric acid and sulfuric acid to boric acid. Boron powder's chemical properties are very active and unstable, has excellent combustion performance, is easy to combine with water vapor in the air, oxygen, the formation of boric acid and other acidic substances, and can be combined with many metals to produce borides. Therefore, storing and transporting boron powder should be careful not to mix with an oxidizer and avoid detonation, rain, and collision.
