1500C Quartz Graphite Crucible For Gold Melting Lab Testing


Application of density quartz crucible:

Industrial alumina ceramic crucible is used for testing laboratory and a variety of industrial analysis.

Alumina ceramic crucible

include: arc alumina crucible, square alumina crucible, rectangle alumina ceramic crucible,

column ceramic crucible.


Application of density quartz crucible:

1.high purity Al2O3 >99%.

2.Superior refractoriness.

3.High mechanical strength.

4.Long life time.

5. High chemical etching resistance.

6. High temperature up to 1800°C

7. Resistant to sudden cold and hot, un-explosive.

8. High density of slip casting.

9. Various kinds of shape.


Alumina ceramic crucible feature

1. Corundum crucible is suitable for melting samples with anhydrous Na2CO3 and other weak alkaline substances as flux, but not suitable for melting samples with Na2O2, NaOH and other strong alkaline substances and acidic substances as flux (such as K2S2O7 and so on)

2. Resistance to high temperature, acid and alkali, cold and hot, chemical corrosion

3. The color is white or beige
