With sheer sintering production process, the product range features very low iron content and high whiteness. 

Since it is non-toxic, tasteless, smoke-dispelling, inflaming-retarding and unique optical character (refractive index 1.57),

 it is widely used in various industries.

We have diversified kinds of products with standard particle and fine-grained sizes available to suit demands for

 different applications.

Packing:
