CORROSION RESISTANT
In addition to hydrofluoric acid, quartz glass has no chemical
reaction withother acid. Its acid resistance is 30 times that of
Ceramic.150 times that of stainless steel Especially the chemical
stability at low temperature.
GOOD THERMAL STABILITY
The thermal contraction coefficient of quartz glass.
Can suffer severe temperature changes.
The quartz glass heated to 1100℃
also will not burst into cold water.
