Alumina Crucibles In Various Industrial Analyzes

QINGDAO YOSION LABTECH CO., LTD. | Updated: May 17, 2017

Corundum crucible, the name of Alumina Crucibles, usually we have more than 95% alumina content of the crucible known as corundum crucible. Arc-shaped Alumina Crucibles, square Alumina Crucibles, alumina corundum ark (rectangular alumina ceramic crucible), straight (cylindrical) Alumina Crucibles and a variety of special-shaped alumina ceramic crucible. Applicable to a variety of laboratory, laboratory, metal, non-metallic sample analysis and melting and various industrial analysis.

  performance

1. Corundum crucible is composed of porous fused alumina, solid and resistant to melting.

2. Corundum crucible suitable for anhydrous NA2O3 and other weak alkaline substances as flux melting samples, not suitable for Na2O2, NaOH and other strong alkaline substances and acidic substances as flux (such as K2S2O7, etc.) melting samples.

3. Corundum crucible characteristics: high temperature, acid and alkali resistance, resistance to cold and extremely hot, resistant to chemical corrosion.

4. Corundum crucible shape: curved, cylindrical type.

5. Corundum crucible specifications: 5-1000ml.

Alumina Crucibles use

1,99.70% corundum 1800 ℃ 1650 ℃ - 1800 ℃ Corundum crucible in the oxidation and reduction atmosphere, has good high temperature insulation and mechanical strength. Thermal conductivity, thermal expansion rate is small. At 1700 ℃ above and air, water vapor, hydrogen, carbon monoxide and so can not react. Short-term maximum temperature of 1800 ℃.

2,99.35% corundum 1750 ℃ 1600 ℃ - 1650 ℃ corundum crucible in the oxidation and reduction atmosphere.

3,85.00% high aluminum 1350 ℃ 1290 ℃ high Alumina Crucibles in the oxidation and reduction atmosphere, has a good high temperature insulation and mechanical strength. Thermal conductivity, thermal expansion rate is small. And air, water vapor, hydrogen, carbon monoxide and so can not respond. In the temperature field temperature change is not the case can be long-term use. Short-term maximum operating temperature of 1400 ℃.
