Jingyue Silica Fume/Micro Silica 94% to 98%

Jingyue Silica Fume/Micro Silica for Refractory 1. Instruction Silica Fume is also called Micro silica, it is a very fine pozzolanic material, composed of amorphous silica produced by electric arc furnaces as a by-product of the production of elemental silicon or ferro silicon alloys. This micro silica used in refractory has a minimum of 92% content of silica, the average content of SiO2 is around 93%. And this undensified micro silica reaches national first grade standard,80% of granularity is less than 0.1 um with a maximum of 0.3 um. 2. Application Micro silica in refractory is a highly effective pozzolanic material, the functions of adding micro silica are as follow: 1)Enhancing the fluid of pouring refractory. 2)Reducing the volume of used water. 3)Be easy to shape. 4)Raising the production efficiency. 5)Rising the compact and intensity of refractory. 3.
