Setene sa Corundum

Melemo ea lihlahisoa: matla a phahameng, ho hanyetsa mocheso o phahameng, ho hanyetsa ts’enyeho, le botsitso bo botle ba lik’hemik’hale.

Tlhaloso ea Sehlahisoa

Litene tse phahameng tse hloekileng tsa corundum li sebelisa “tabular corundum” le “fused corundum” e le lisebelisoa tse ka sehloohong tse sa tsoakoang, ka maemo a mahlale le a utloahalang, a nang le li-additives tse sebetsang hantle haholo, ho bopa khatello e phahameng, ho sintering mocheso o phahameng, ‘me lihlahisoa tse hanyetsang li tšoauoa ka matla a phahameng le mocheso o phahameng. ho hanyetsa. Ts’ireletso ea ts’enyeho le botsitso bo botle ba lik’hemik’hale.
