Fused Silica ceramic use fused silica or silica glass as raw material,adopt the ceramic production techniques to make of fused silica material. It has the feature of small thermal expansion coefficient and good thermal stability, good electrical insulation,good resistance to chemical corrosion (except hydrofluoric acid and 300℃ concentrated phosphoric
 acid), low thermal conductivity, good machinability. Furthermore it has a feather not same with the other ceramic material,its
 strength will increase as the temperature higher.
 We could provide the rollers as per your specification and drawings.
