Quartz Crucibles

Description

Quartz Crucible Quartz crucibles are at ***0 degrees below the use of two kinds of sub-transparent and opaque. The rule of law with the arc is drawn semi-transparent quartz crucible large-diameter silicon, an essential foundation for the development of large scale integrated circuit materials. Today, the world&#**9;s semiconductor industry in developed countries has been replaced with this crucible of small transparent quartz crucible. It has high purity, strong heat resistance, size large, high precision, good insulation, energy conservation, quality, stability and so on. Quartz crucible can be burned at ***0 degrees below, but the ignition temperature is higher than ***0 degrees of quartz becomes opaque, so the melting temperature should not exceed **0 °. HF can not contact, At high temperature, it&#**9;s easily affecting with causticity alkali and alkali metal carbonate . Quartz crucible is suitable for K2S2O7, KHSO4 as the flux for melting the sample as well as the Na2S**7 (first in the ***-degree dry) . Quartz is easy brittle and break , so note when used it. In addition to HF, the ordinary dilute inorganic acid can be used as cleaning fluid.
