Zirconium powder preparation:

The preparation methods of zirconium powder commonly used in industry are 

mainly metal thermal reduction, hydrogenation dehydrogenation and electrolysis.

Zirconium powder application:

Zirconium powder is widely used in industry. For example, the zirconium powder 

obtained by hydrogenation dehydrogenation can be used as the fuse of the artillery 

shell and the heating sheet of the thermal battery and burning agent. The thermal 

battery is the heat source of the rocket missile control system. Zirconium powder 

reacts with barium chromate in the thermal battery to release heat quickly activate 

the battery so that the device quickly enters the working state. Zirconium powder 

is mostly used in large electric vacuum tubes with good effect. Large tube is an 

important part of broadcasting, communication and radar facilities such as the role 

of zirconium powder in the large tube is to absorb the residual gas in the tube, so 

that it can maintain a high vacuum degree during use, reduce the electron thermal 

emission of the gate, and use its high melting point, low vapor pressure characteristics 

to maintain the transparency of the vacuum tube glass, which is conducive to the heat 

dissipation of the tube. The tube can maintain the normal working state for a long time 

and solve the problem of cathode poisoning of the tube.
