HY-C-25
Product Description
HY-C-25 is one kind of 325 mesh calcined kaolin，with chemical composition of anhydrous aluminum silicate. HY-C-25 with pure quality，less impurity，high kaolin content above 98％，extremely low Fe₂O₃, after high temperature calcination，it has high brightness, stable color and the refractoriness up to 1750℃, with high volume density.
HY-C-25 offers resonable particle distribution, good dispersion, processing performance and strong chemical stability. Widely used in ceramic industry.
