Tlhaloso e Khutšoane

Tabular Alumina ke thepa e hloekileng e kentsoeng ka mocheso o phahameng haholo ntle le li-additives tsa MgO le B2O3, microstructure ea eona ke sebopeho sa polycrystalline se nang le mahlakore a mabeli se nang le likristale tse kholo tse hōlileng hantle tsa α - Al2O3.Tabular Alumina e na le li-pores tse ngata tse nyenyane tse koetsoeng ka kristale ea motho ka mong, litaba tsa Al2O3 li feta 99% .Ka hona e na le botsitso bo botle ba molumo le ho hanyetsa mocheso oa mocheso, ho hloeka ho phahameng le ho hanyetsa, matla a babatsehang a mechine, ho hanyetsa abrasion khahlanong le slag le lintho tse ling.
