Product detail
Pyrophyllite Brick
Pyrophyllite brick is a refractory product made of natural pyrophyllite as raw material, through rationalized batching, mixing, high-pressure pressing, and high-temperature sintering. Mainly used for the permanent layer of the ladle, the working layer of the ladle, the working layer of the casting ladle, etc.
