Silica fume, also known as microsilica, is an amorphous (non-crystalline) polymorph of silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy production and consists of spherical particles with an average particle diameter of 150 nm.
Typically, fused silica is cut using band and wire saws as well as chop saws. The cut loss and surface quality depends on the machine and the feed speed. It is also possible to cut fused silica using CO2-Lasers or a water jet machine. While a laser produces flame-glazed surfaces, a water jet produces a rougher surface.
