corundumrelated
Corundumrelated refers broadly to corundum (aluminum oxide, Al2O3) and materials, minerals, and products that are compositionally, structurally, or commercially associated with it. Corundum is a hard (9 on the Mohs scale), dense, trigonal crystal that forms gem-quality varieties—ruby (red, colored by chromium) and sapphire (blue and other colors, often colored by iron and titanium)—as well as industrial-grade material used for abrasives and refractories.
Minerals and oxides that share structural or chemical affinities with corundum are often described as corundum-related.
Human-made corundum-related materials include synthetic gem corundum (produced by Verneuil, Czochralski, or flux-growth methods), transparent aluminum
In mineralogy and materials science, the term emphasizes relationships defined by crystal structure, chemistry, industrial processing,
