Small expansion coefficient Refractory Mullite batts for kiln
1. Description
Mullite batts are made of Magnesium Aluminum Silicate which has very low thermal expansion and low thermal conductivity.Mullite can withstand fast heating or cooling and is used when thermal shock is a concern traditionally used in top loading electric kilns. Mullite batts are more susceptible to warping at higher temperatures with maximum firing temperature is cone 8. Shelves used up to cone 6 should be at least ¾” thick, and those used to a maximum of cone 10 should be at least 1” thick which makes them heavy. Mullite has 13-25% porosity rate which will be a problem with glaze dripping (the glaze can easily penetrate the surface and melt into the shelf). Kiln wash should therefore be used to protect the surface. Mullite kiln shelves are not recommended for salt or wood firings.
The product has good features of high temperature resistance, high strength,good thermal shock resistance,high thermal conductivity, and other characteristics.
