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.
