Detailed Product Description

White silica  was made by choiceness high qualiy ore with complex processing. My companys product was made of natural quartz ,which is made through the offal, washing and selecting.

(1) Quartz sand hardness of 7.5.the proportion of 2.66.

(2)Size:0.5-1mm,1-2mm,2-4mm,4-8mm,8-16mm,16-32mm

It main usage filter material,highgrade glass,precision casting spray sand .etc .Meanwhile, We can produce  according to user s requirement ,white or crystalline appearance.We also used the new craft of the material of purification
