Corundum crucible is strong and resistant to melting, high temperature, acid and alkali, rapid cooling and extreme heat, and chemical corrosion. It is suitable for some weakly alkaline substances such as anhydrous Na₂CO₃ as a flux to melt samples, but it is not suitable for Na₂O₂, NaOH, etc. Strongly alkaline substances and acidic substances are used as fluxes to melt samples.The alumina crucible with a purity of 99.70% has good high-temperature insulation and mechanical strength in a redox atmosphere of 1650℃-1700℃, and the maximum temperature can reach 1800 in a short time ℃. Alumina crucibles are available in a variety of sizes and shapes depending on the application conditions.

Features

Strong and resistant to melting, high temperature, acid and alkali, rapid cooling and extreme heat, and chemical corrosion.

Main uses of alumina crucibles

(1) Transpiration, concentration or crystallization solution.

(2) Burn solid materials.

Precautions for using crucibles

(1) It can be heated directly. It cannot be cooled suddenly after heating. Use a crucible support crane.

(2) Heat the crucible on an iron tripod.

(3) Stir when steaming; use residual heat to steam dry when nearly steaming.
