Refractory Silica Fume/Undensified Silica Fume
Silica Fume ia also calledMicro silica, it is a very fine pozzolanic material, composed ofamorphous silica produced by electric arc furnaces as a by-productof the production of elemental silicon or ferro silicon alloys.This micro silica used in refractory has a minimum of 92% contentof silica, the average content of SiO2 is around 93%. And thisundensified micro silica reaches national first grade standard,80%of granularity is less than 0.1 um with a maximum of 0.3um.
Undensified microsilica is one of our most competitive products, we sellthis product at 1000MT per month to all over the world, such asKorea, the Middle East, India, Indonesia and so on.Our refractory grade silica fume is satisfied by our customersfor its good quality and competitive price.
