Microsilica By Gansu Sanyuan Microsilica Co., Ltd.

This Microsilica comprises microscopic particles collected by filters downstream from the smelting process in silicon and ferrosilicon plants. Adding it to concrete and other materials, increases their density and wear resistance, which extends the life of structures. Micro Silica stands average diameter is between 0.1um and 0.15um. Its specific surface area is between 15a /g and 27a /g, which have superpower surfactivity. It finds a wide range of applications in project construction, Refractories, and high-strength concrete. Our product is classified densitied and undensitied Micro Silica, its main chemical ingredient is SIO2 (85~95%), including also Fe2O3, AI2O3, CaO, K2O, MO, C, etc.
