1. Different purity 85%-98%
2. High fluidity, increasing strength
3. Improve consistency
4. Meet ASTM C-1240
Microsilica JH95 is a dry powder available in two forms,densified
silica fume and undensified silica fume.
Microsilica JH95 is a pozzolanic material that consists primarily
of fine silicon dioxide particles in a non-crystalline form.
Microsilica JH95 contains a minimum of 95% silicon dioxide (SiO2)
Microsilica JH95: We have three factories in Shanxi, Yunnan and
Qinghai Province, China. Stable quality and reasonable price.

- HS No.: 28112200 China Origin, microsilica meets the requirements of ASTM C-1240.
- Microsilica CAS #: 69012-64-2
Main function
- Microsilica in refractory enhancing the fluid of pouring refractory, reducing the volume of used water, be easy to shape, and raising the production efficiency.
- Because of its ultra microstructure for gap filling, the compact and intensity of refractory gain rising by a wade margin.
- Microsilica in refractory is a highly effective pozzolanic material, so it's easy to come into being Mullet Phase, under the premise that Al2O3 exists, enhance elevated temperature strength and thermal shock of refractory.
- Microsilica in refractory is used in Microsilica in refractory is used in unshaped,shaped gunned refractory materials to improves adhesion in castables and minimizes rebound loss.
