Mullite sand/powder

Mullite sand/powder is produced through a high-temperature calcination process and is a high-quality casting sand made from high-quality kaolin mines. The main crystalline phase is mullite. Has a lower thermal expansion rate, uniform expansion, better vibration resistance, good hardness and other properties. Very suitable for precision casting.

Features:

1. High refractive index, low thermal expansion rate;

2. Good thermochemical stability;

3. Good grain shape, uniform size distribution;
