Silica sand, also known as quartz sand, white sand, or industrial sand, is made up of two main elements: silica and oxygen. Specifically, silica sand is made up of silicon dioxide (SiO2). The most common form of SiO2 is quartz – a chemically inert and relatively hard mineral.
Micro silica also known as fume, is an amorphous
(non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon & ferrosilicon alloy production & consists of spherical particles with an average particle diameter of 150 mm.
Fused Quartz Powder
Fused silica as an industrial raw material is used to make various refractory shapes such as crucibles, trays, shrouds, & rollers for many high-temperature thermal processes including steelmaking, investment casting, and glass manufacture
