Has good chemical stability. According to a query on Zhihu, zirconium powder has good chemical stability, thermal stability and mechanical strength, and can be used to remove various ions and particles in water, so zirconium powder is washed with water. Zirconium powder is used in the production of fireworks and weapons. Zirconium can also be used as chemical raw materials to produce zirconium oxide and other zirconium-containing compounds. Zirconium powder is very easy to spontaneously ignite and will cause combustion and explosion when exposed to heat, open flame or contact with oxidants.
