Alumina Classic Crucible
The Alumina Classic Crucible is one of Goodfellow's range of ceramic crucibles used in high temperature laboratory applications. With 9 variations available, including sizes from 15ml to 500ml, these crucibles provide excellent thermal shock resistance and high purity. The alumina material enables use to over 1800°C in vacuum or inert atmospheres. Typical applications for the Alumina Classic Crucible include serving as containers for metal melting, glassmaking and calcination processes. These crucibles are also suitable as boats for the zone refining of semiconductors.
