Chemical Inertness:
Fused quartz does not react with acids with the exception of hydrofluoric and at high temperatures phosphoric. There is a slow reaction with caustic alkalies at normal temperatures. There is no reaction with water and steam at moderate temperatures and pressures.
We can supply more than 5 types and 70 speculations, ranging from 3-300mm clear quartz tube(high purity, good heating resistance, low OH), UV-stop quartz tube, red quartz tube, processed quartz tube, quartz rod, quartz plate, gray quartz tube, and so on. And we have further capacity of trim cutting, fire-polishing, pinching, and bending, and so on.
After-Sale service:
