Mullite occurs very rarely in nature because it only forms at high temperature,low pressure conditions.
So as an industrial raw material,mullite has to produced by synthetic processes.Mullite is a material on upscale pricing and known for its excellent thermal and machanical properties:low thermal expansion,low thermal conductivity,excellent creep resistance,suitable high temperature strength and outstanding stability even under harsh chemical conditions.
Feature of mullite setter plate:
short heating-up times
fully automatic operation of the facility
low energy consumption
straightforward operation and process control
temperature uniformity throughout the whole charge of < 6 K
long service life of key components
no damage to ingot surfaces
