corundumbased

Corundumbased refers to materials whose primary component is corundum. Corundum is a crystalline form of aluminum oxide with the chemical formula Al2O3. It is known for its exceptional hardness, ranking 9 on the Mohs scale, making it one of the hardest naturally occurring minerals. Its high melting point, chemical inertness, and excellent electrical insulation properties also contribute to its widespread use.

Materials referred to as corundumbased can encompass a range of products where corundum, either in its natural form or synthetically produced, is the key ingredient. This includes abrasives, such as sandpaper, grinding wheels, and polishing compounds, where its hardness is utilized to shape and smooth other materials. In refractories, corundumbased bricks and monolithic linings are employed in high-temperature applications like furnaces and kilns due to their resistance to heat and chemical attack.

The production of synthetic corundum allows for tailored properties and purity for specific industrial needs. These synthetic forms are often used in applications demanding higher performance and consistency than naturally occurring corundum can provide. Examples include components in the aerospace industry, wear-resistant coatings, and even in some types of ceramic armor. The term "corundumbased" therefore signifies a reliance on the inherent strengths of Al2O3 for material performance.
