Crack-free ductile mode grinding of fused silica …

A crack-free ductile mode grinding of fused silica was realized by a controllable dry grinding process in this research, which is attributed to the improvement of fused silica's ductile machinability induced by the high grinding temperature. The plastic deformation of fused silica consists of shear flow and densification. Plastic deformation mechanisms and cracking behaviors related to ...

Materials | Fused Silica - Specialty Glass Products

Fused Silica is a result of melting synthetically derived silicon dioxide and is used in many of the same applications as fused quartz. The main differences are that fused silica transmits better in the UV and fused quartz is lower in OH content. Both are highly pure, have high chemical resistance, good thermal shock resistance, and low thermal expansion coefficient. SGP can CNC mill, cut ...

Shaping and forming of fused silica - Heraeus

Grinding; Milling; Hot forming. A lot of experience is necessary to do hot forming of fused silica. Due to the high melting point and its steep viscosity, the temperature range in which it can be processed is rather narrow. If the temperature is too low, fused silica is solid, if it is too high, it gets very soft, almost liquid and it evaporates to form soot dust. Additionally hot processing ...
