Description

Many use for this coarse mullite with cement binder to insulate heating pipes, formulated coating for welding arc electrodes. Thermal shock resistant ceramic wares. Knife and sword forgers find mullite and fine clay binder mixture as clay tempering to create hamon designs commonly found in Japanese katana.

Available in fine #325 and coarse #50.

Mullite Ceramic Properties

Mullite is a good, low cost refractory ceramic with a nominal composition of 3Al2O3•2SiO2. The raw materials for mullite are easily obtainable and are reasonably priced. It has excellent high temperature properties with improved thermal shock and thermal stress resistance owing to the low thermal expansion, good strength and interlocking grain structure.
