Alumina Crucibles

alumina crucibles

Manufactured from 99.8% pure aluminum oxide, these high-form crucibles are highly resistant to chemicals, ethanol, isopropanol alkalines, aldehydes, aromatic solvents, hydrogen peroxide, acetic acid, and peracetic acid. These crucibles have a high resistance to most acids, bases and metals. Not suitable for use with hydrofluoric acid, sodium metal, lithium metal. 99.8% pure Alumina crucibles are chemically inactive in hydrogen, inert gases and carbonaceous atmospheres. These crucibles are autoclavable. The Alumina material is unglazed, as such it can withstand higher temperature.
