A. The alumina crucible has good resistance to rapid heat and cooling and is not easy to burst.
B. The alumina crucible is formed by grouting, so the density is high.
C. Corundum crucible has good high-temperature insulation and mechanical strength in oxidation and reduction atmosphere, high thermal conductivity, low thermal expansion rate, and does not react with air, hydrogen, water vapor, carbon monoxide, etc. above 1700°C.
Alumina Laboratory Crucible
My factory looking for distributors.
Alumina cruciblesare also called corundum crucibles. The shapes are mainly cylindrical, conical, arc, box-shaped, etc. The purity of alumina crucibles is high, containing more than 99% of AL2O3.
No: C59#
Shape: Conical
Size: φ48/30*52 mm
Certificates: DIN43724/DIN43725/DIN40680 and SGS
Alumina Laboratory Crucible Mainly Using
Burning solid substances
Evaporation, concentration or crystallization of the solution
Alumina laboratory crucibles are suitable for melting samples with anhydrous Na2C03 and other weakly alkaline substances as fluxes, laboratory test crucibles are not suitable for melting samples with Na 202, NaOH and other strongly alkaline substances and acidic substances (such as K2S 207 and so on) as fluxes.
Alumina laboratory crucible is composed of porous fused alumina, which is firm and refractory. We use 99.3%-99.7% high purity alumina which can work max 1800C.
