Mullite

Offering a range of refractory minerals that is the most suitable for foundry and refractory industries, Mullite is one of them artificially produced for industry by melting or firing various alumino-silicates. It has good thermo-mechanical properties and stability which is most suitable for use in many refractory and foundry applications. 20 Microns offers various sizes of powder and granules to meet the requirement of end applications whether it is a foundry coating system, investment casting, or refractory, this synthetically produces Mullite has a very high melting point. It has very good creep resistance, it has low porosity, thermal expansion, and conductivity, and is stable in a harsh chemical environment.

Products:

• Hyper Grain IR: Crystallined Calcined Kaolin with needle-like crystal structure that is very resistant to thermal shock failure (has a low thermal expansion).
