Mullite refractory castable has passed ISO certification.It has
good thermal shock resistance and can resist high temperature.
Mullite Refractory Castable is made of high purity mullite raw
materials.Its good bulk stability make it has high thermal shock
resistance.Mulllite refractory castable has the advantage of high
refractoriness under load,low creep under high temperature,stong
hardness,erosion-resistance and so on.
