1.Alumina crucibles

Alumina Crucibles are manufactured for more than 20 years and have a skill production technology in different shapes and range of sizes from few milliliters to several liters, these fully dense, high purity an high temperature use,fine grain products find use in a range of high temperature applications such as metal processing / molten glass, rapid thermal cycling, gemstone purification for jewelry industry etc. Majodrity of applications require the ceramic to be impervious, porous forms can also be made on order.

Property:
Purity:≥99.7%
Density:3.85g/cm3
Compressive Strength:2500Mpa
Flexural Strength: 360Mpa
Thermal Shock : good
Max service temperature: 1800℃
