[0002] Copper oxide is an inorganic substance with the chemical formula CuO. It is a black oxide of copper, slightly amphoteric, slightly hygroscopic, insoluble in water and ethanol, easily soluble in acid, thermally stable, and decomposes into oxygen at high temperatures. A certain mass of CuO and NaN mixture is installed in the car airbag. When the car collides violently, the reaction 2NaN2+CuO=Na2O+3N2↑+Cu occurs in the airbag, thereby filling the airbag with nitrogen. Therefore, copper oxide needs to be made into powder and then used in the airbag.
