Undensified Silica Fume
1. Silica fume, also known as microsilica, it is a very fine pozzolanic material, composed of amorphous silica produced byelectric arc furnaces as a byproduct of the production of elemental silicon or ferro silicon alloys.Silicafume can be used in a variety of cementitious products such as concrete,grouts,and mortars as well as elastomer, polymer,refractory, ceramic and rubber applications.
2. Main function
HS No.: 28112200 China Origin, microsilica meets the requirements of ASTM C-1240.Microsilica CAS #: 69012-64-2Microsilica 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.3.Specification of JH97 Microsilica
