Alumina High Form Crucibles

Alumina high form crucibles are specialized containers crafted by LSP Ceramics from high- purity aluminum oxide (Al2O3), renowned for their high-temperature resistance, chemical inertness, and mechanical strength. These crucibles are designed with a tall, narrow profile, ideal for applications requiring minimal contamination, like chemical calcination or metal casting. They can withstand temperatures up to 1750°C-1800°C, offering excellent thermal shock resistance due to the material’s properties. Their high purity (often >99%) ensures they are suitable for sensitive processes in laboratories and industries, providing a reliable, contamination-free environment for various experimental and industrial uses.
