Nano-zirconium powder is prepared by vapor phase CVD method. It has high purity, high sphericity, low bulk density, uniform particle size, narrow distribution range, large specific surface area, high surface activity, spherical shape, good dispersion, high oxidation temperature and luster, so its appearance is similar to steel. It is corrosion-resistant and soluble in hydrofluoric acid and aqua regia. It can react with non-metallic elements and many metal elements at high temperature to form solid solution compounds.
Nano-zirconium powder is mainly used in:
1. Absorbent: Zirconium can absorb nitrogen, hydrogen and oxygen as strongly as lithium and titanium. At room temperature, Nano-Zirconium can absorb nitrogen, oxygen and hydrogen violently.
2. The characteristics of Nano-Zirconium powder are low ignition point and fast burning speed. It can be used as the initiating explosive of detonator. This kind of advanced detonator can explode even under water. Zirconium powder plus oxidizer. It's like fueling a fire and burning with a strong glare. It's a good material for making tracer and illuminator.
3. Military Use: From the military point of view, as long as one thousandth of zirconium is added to the steel, the hardness and strength will be amazingly improved. Zirconium-containing armor steel, artillery forging steel, stainless steel and heat-resistant steel are important materials for making armored vehicles, tanks, artillery and bullet-proof plates.
