Calcined Flint Clay

Calcined flint clay is a main raw material for manufacturing high grade refractory materials, refractory brick, various ceramics, precision casting sand, ceramic fiber, refractory furnace burden, crucible, kiln furniture, saggar, monolithic refractory materials, etc.

Our company is located in the main producing area and rich resources of calcined flint clay. Our plant produce calcined flint clay characterized by high bulk density, low impurity, stable physicochemical performance, high refractory temperature resistance, etc. It is widely used in metallurgy, casting, chemical industry, ceramics, electricity, machinery, oil and so on.
