Alumina Dish Description
The Alumina Dish is composed of Aluminum Oxide (Al2O3). Alumina, a significant ceramic oxide, is crucial in fields like electronics, medicine, and more. With a high melting point (2054℃) and chemical stability, it's used in high-temperature and contamination-free reactions. Alumina's refractory nature lets it handle up to 1750℃ in various atmospheres. It's also a valued electrical insulator, often as a substrate for integrated circuits. With its affordability, robust properties, and broad applicability, Alumina finds use across diverse industries.
