Description
Our company's flint clay products are based on high-quality natural clay ore as raw materials and calcined in natural gas shaft furnaces at high temperatures. It has the advantages of high whiteness, low impurity content, low shrinkage, high volume density, stable physicochemical index, good fire resistance and processing granularity standard. It is the ideal raw material for producing refractory brick, aluminum silicate refractory fiber, refractory castable, precision casting, refractory furnace material, kiln ware, sagger, crucible, etc.
