Fused Mullite

Product Overview

Description

 

Fused mullite selection of natural minerals used as raw materials, multi-stage homogenization process, with special high-temperature calcination synthesis of mullite and high-silica glass composite microstructure of mullite as raw material. The material has a thermal expansion coefficient is small, excellent high temperature stability and good performance, is the production of high-quality mullite kiln furniture most suitable raw materials.
