99% Alumina Saggar

This product is a 99% alumina saggar designed for high-temperature sintering and calcination processes in advanced materials research. Manufactured by Canrd using slip casting or die casting techniques and fired at 1800°C, it offers reliable thermal stability up to 1600°C. The dense corundum structure provides excellent chemical resistance and mechanical strength for repeated use in furnace environments. Typical applications include holding powders, pellets, or small components during solid-state reactions, ceramic synthesis, or battery material preparation. The saggar is available in multiple dimensions with optional covers that serve as dust protection (not airtight). Before first use, a pre-baking step at 105°C for two hours is recommended to remove moisture, and controlled heating/cooling rates are advised to prevent thermal shock. Custom sizing is supported, though customized items are non-returnable unless defective.
