Innovacera is a professional manufacturer of technical ceramics.

Innovacera has a complete range of advanced technical ceramics for a wide variety of applications.

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.

Industrial alumina ceramic crucible is used for testing laboratory and a variety of industrial analysis.

We can supply 99% and 99.5% alumina ceramic crucible and zirocnia ceramic crucible according to customer's drawings, samples and performance requirement.
