    1. Product introduction

    Wollastonite belongs to triclinic, crystal usually extends along Y-axis and becomes board shape, bacilliform or acicular. Pure wollastonite appears to be white, ivory-white light gray, light green or pink colour. Its appearance has vitreous luster.

    Our company can manufacture many kinds of fine wollastonite powder, it is all manufactured by high quality raw materials. It has many good characteristics, such as granularity equality, homogeneous, high purity, endless catenulate, acicular crystallize, high whiteness, low ferrous, minimum S, P, low oil-absorption and etc.

    3.Ceramic grade wollastonite

    1) 200 mesh to 325 mesh

    2) when sufficient wollastonite is added to ceramic material, the

    Baking temperature can be decreased, and the baking duration greatly shortens to one rapid low temperature bake, thus saving fuel and reducing production costs

    3) at the same time the mechanical properties are improved, cracks and streaks on the products are eliminated and quality raised
