FAQ

High strength: High thermal shock resistance, can maintain high mechanical strength even under rapid temperature rise or high temperature operation conditions, effectively avoiding the risk of breakage and leakage during the production process.

Corrosion resistance: prevents eluted pollutants from entering the molten metal, which is the key factor in maintaining the purity of the molten metal.

Anti-wetting: Low wettability to molten metal, almost no reaction with molten aluminum, making daily maintenance easier.

What are the advantages of Silicon Nitride?

Compared with other technical ceramics, the low thermal expansion coefficient of Silicon Nitride provides good thermal shock resistance. It is extremely hard, fracture-tough, surpasses the high temperature capabilities of most metals, and also has a superior oxidation resistance. As a consequence, silicon nitride can withstand the toughest conditions in the most demanding high-temperature and high-load applications.

What is the formula for Silicon Nitride?

The formula for silicon nitride is Si3N4.
