United Scientific Cylindrical Form High Alumina Crucibles are made of 99.7% pure aluminum oxide. Highly resistant to chemical attack, this alumina-ceramic ware is especially useful to chemists, metallurgists and others involved in high temperature work demanding contamination-free results.
- Conical form, unglazed, 99.7% alumina crucible
- Maximum use temperature is 1750°C
- Temperature change rate should not exceed 150°C/hour
High alumina ware is highly refractory, meant for use in reducing and oxidizing atmospheres. It is inert in hydrogen and carbonaceous atmospheres and offers high resistance to alkalies and other fluxes. Suitable for glass melting, including borosilicate glass.
Recommended for use with refractory metals such as molybdenum, platinum, rhodium, tungsten, tantalum and iridium.
