Alumina kemịkal dị iche iche, dịka ọkọlọtọ ụlọ ọrụ ígwè na-abụghị ferrous YS/ ton 619-2007 si kwuo "ụdị alumina kemịkalụ na aha akara", dịka ihe mejupụtara kemịkalụ nke alumina kemịkalụ si dị, a kewara ya n'ime ụdị ise: usoro alumina hydroxide, usoro alumina oxide pụrụ iche, usoro alumina quasi thin, usoro zeolite na usoro simenti calcium aluminate.
Ugbu a, polyaluminium chloride, sodium silicate, nnu fluoride na nnu aluminom ndị ọzọ, sodium aluminate, gallium na gallium compounds, akụkụ nke seramiiki alumina na corundum refractories sokwa n'òtù alumina kemịkalụ.
Na 1910, Alcoa mepụtara ma ree otu mbụ nke alumina alumina a na-akpọ calcined n'ụwa, nke bụ ihe e ji emepụta ihe ndị na-eme ka abrasives ọcha dị ọcha.
