Zirconium powder  

Molecular formula: Zr  

CAS：7440-67-7 

Melting point (℃): 1852 

Properties: Zirconium powder is a gray powdery metallic zirconium with ultra-high hardness and strength, as well as good mechanical and heat transfer properties, and excellent luminescent properties. Zirconium powder is prone to absorbing hydrogen, nitrogen, and oxygen, and can directly combine with dissolved oxygen, nitrogen, and hydrogen at high temperatures, making it easy to burn.

Preparation process: Hydrogenation dehydrogenation method: Heating zirconium metal in hydrogen gas to generate hydrogenated zirconium, which is then crushed and dehydrogenated to obtain zirconium powder. 

Purpose: 

Main purpose 

1. Additives for high hardness alloys: Zirconium powder can be used as an additive for high hardness alloys to enhance their performance. 

2. Electric vacuum and light bulb industry: Zirconium and zirconium alloys are widely used as non evaporative gas scavengers in the electric vacuum and light bulb industry to create super vacuum environments, improve vacuum quality, and extend equipment service life. 

3. Flash and fireworks materials: Zirconium powder is used to create flash and fireworks materials, providing bright colors and effects. 

Bulletproof alloy: Zirconium powder is used to manufacture bulletproof alloys, providing excellent protective performance. 

4. Ceramic industry: Zirconium powder is used to manufacture ceramic raw materials and coatings, improving the quality and durability of ceramic products. ‌ 

5. Electronics industry: used for manufacturing electronic components and electronic ceramics to enhance the performance and stability of equipment. 

6. Chemical industry: As a catalyst and fireproof material, it promotes chemical reactions and improves the fire resistance of materials. 

7. Pharmaceutical industry: used for manufacturing medical ceramics and coatings, providing biocompatibility and corrosion resistance. 

8. Aerospace industry: used for manufacturing gas turbine blades and aviation engine components, capable of withstanding extreme high temperature and high pressure environments. 

Storage and transportation: Fine powders are prone to form explosive mixtures in the air and require anti-static and dust-proof measures. Sealed and stored in a dry inert gas (such as argon) or water, away from oxidants and acids.
