Mullite MC-O

Description:

Mullite MC-O is produced by use of local high quality kaolin in Mongolia.The chemical composition of MC-O is similar to Molochite (UK) and its properties are the same.

Features:

Mullite MC-O has the characteristics like low thermal expansion coefficient, high chemical stability and corrosion resistance, good mold shell performance, low iron and dust content, stable casting and excellent shelling performance.

Application:

Mullite MC-O is mainly used for the ceramics, kiln furniture and investment casting.
