<p>This colloidal silica soot is a byproduct of chemical vapor deposition processing of fused silica or ultra low expansion glasses. The colloidal silica byproduct is referred to as 'soot'. Retaining the same physical properties as the parent glass and having a spherical morphology, the colloidal silica soot is an ideal candidate for final polishing applications of optical fluoride crystals (44), and particularly for optical fluoride crystals (44) such as calcium fluoride which have high transmission levels to below 300nm light such as produced by excimer lasers. The soot has a large particle size and spherical shape when compared to conventional colloidal or fumed silica</p> |
