We are the leading Chinese Supplier and Exporter of Silica fume(Microsilica), what has been exported to Saudi Arabia, Qatar, Kuwait, Japan,Brazil, India, Vietnam,UAE,

 Finland,Indonesia, Philippines, and so on.Our silica fume mostly comes from Yunan province, this means High Pozzolan Activity. Standard specifications for silica fume used as concrete admixture are ASTM C1240. 

Welcome the silica fume dealer and dealership in the foreign market for further 

cooperation.

PROPERTIES

--Silica sand is a kind of hard and wearable silicic acid mineral with stable chemical properties. It is ivory or without color and translucent.

--The main component is SiO2 ,hardness is 7 and relative density is 2.65. Silica sand is not dissoluble in acid, melting point is 1750.c.

APPLICATION

Because of special physical properties, chemical properties and strong resistance to acid medium, the silica sands play an important role in many applications as below:

--GLASS: primary materials for sheet glass, glass products (glass pot, glass tube, etc), fiberglass, glass cloth, ect.

--CERAMIC AND FIRE-PROOF MATERIAL.

--METALLURGY: as chemical additive or melting agent for silicon metal, ferro-silicon alloy, ect.

--CONSTRUCTION: Concretes, road material, artificial marble, ect.

--CHEMICAL INDUSTRY: raw material of Silicon compound and sodium silicate, etc.

--MACHINERY: primary materials for Casting molding sand, abrasive substance (sand blasting, sandpaper, etc.)

--ELECTRON: for the high-purity metallic silicon, optical fiber, etc.

--RUBBER, PLASTIC: as the filler material for enhancing wear resistance.

--COATING: as the filler material for enhancing weathering resistance.
