Boron powder is a black or dark brown powder, which can react with fluorine at room temperature and will not be corroded by alkali and hydrofluoric acid aqueous solutions. Boron powder is also called amorphous boron. Boron has a high mass calorific value and volume calorific value. It is a light brown to gray-black powder with relatively active chemical properties, but it is relatively stable at room temperature and will be oxidized when the temperature reaches 300 degrees Celsius. The ignition level is very high, requiring 700 degrees Celsius to ignite. Boron powder can react with oxygen, nitrogen, and sulfur, or it can directly combine with certain metals to form certain borides.
