Zirconium and gas have strong affinity. They react with oxygen, hydrogen and nitrogen at about 200, 300 and 400 ℃ respectively. The reaction is rapid at higher temperature. Therefore, the melting and heat treatment should be carried out in vacuum furnace. When heat processing is carried out in the atmosphere, proper protection measures shall be taken and the operation time under high temperature shall be shortened.
