High Density Refractory Raw Material Zirconium Powder Zircon Powder
Description of Hot Selling High Quality Zirconium Powder / Zircon Powder
Zircon is extremely resistant to high temperatures, with a melting point of 2750, and is resistant to acid corrosion. 80% of the zircon in the world is directly used in the foundry industry, ceramics, glass industry and the manufacture of refractories. A small amount of zircon is used in ferroalloy, medicine, paint, tanning, abrasives, chemical and nuclear industries. A very small amount of zircon is used to smelt metal zirconium. The zircon sand containing ZrO265~66% is due to its melting point (melting point above 2500℃)
Features of Zirconium Powder / Zircon Powder
The advantage of Zircon Powder For Ceramic
1. Good chemical stability and low wettability prevent sand sticking on castings. It can avoid metal penetration into the mould.
2. Low thermal expansion coefficient make casting precise shape and prevent casting unshaped.
3. Get better surface finish of metal/steel casting.
4. High Recyclability.
5. Low wettability and high chemical stability will get recycled sand easy to clean and get uniform particles.
Application of High Quality Zirconium Powder / Zircon Powder
It is used in a variety of applications, including ceramic frits, foundry mould coatings, ceramic shells for investment casting, refractories, friction products, insulating fibres and glass.
