Recent years some custumers who took our Garnet Abrasives asked us to supply with Black Silicon Carbide, some others asked us to supply with Brown Fused Alumina, therefore we began the export of Black Silicon Carbide, Brown Fused Alumina as well. And partner factories are situatedin western Inner Mongolia and neibouring areas.
