Transparent quartz glass crucible flat bottom small crucible
Quartz crucible can be used under 1450 degrees, divide into two kinds of transparent and opaque.
1. It has high purity, temperature tolerance, high accuracy, good heat preservation and energy saving, stable quality, etc.
2. Quartz crucible on the thermal stability is good, can be directly on the flame heating.
3. High temperature resistant up to 1200-1500 degrees.
4. The main chemical composition is silica, quartz crucible except hydrofluoric acid and other acids, easy and caustic alkali and
alkali metal carbonate.
5. In addition to HF, ordinary dilute mineral acid can be used as a cleaning fluid.
6. Quartzose fragile, easily broken, should pay attention to when using.
7. With a quartz crucible can use potassium hydrogen sulfate (sodium), sodium thiosulfate (dried at 212 degrees Celsius) as
solvent, such as melt temperature no more than 800 degrees Celsius.
