1.Getter

For example, in the electric vacuum industry, people widely use zirconium powder coated on the surface of the anode and other heated parts of the electric vacuum components and instruments, absorb the residual gas in the vacuum tube, make the high vacuum tube and other electric vacuum instruments, so as to improve their quality and prolong their use time.

2. Metallurgical effect

It has powerful deoxidation, nitrogen removal and sulfur removal.
In addition, zirconium powder is characterized by a low ignition point and a fast combustion rate, which can be used as a primer for initiating detonators, which can explode even underwater. Zirconium powder plus oxidizer. It's like adding fuel to a fire, which burns with blinding light, making tracer bullets and flares.

3. Zirconium alloy

Zirconium has excellent corrosion resistance to a variety of acids, alkalis and salts, and has a strong affinity with gases such as oxygen and nitrogen, so zirconium alloys are also used in the manufacture of corrosion resistant parts and pharmaceutical machinery parts, in the electric vacuum and bulb industry is widely used as a non-evassive degasser.
