Aluminum Oxide Pauda Introduction
ʻO ka pauka alumina he mea maʻemaʻe kiʻekiʻe, maikaʻi i hanaʻia mai ka alumini oxide (Al2O3) i hoʻohana nuiʻia i nāʻanoʻoihanaʻoihana.ʻO ia ka pauka crystalline keʻokeʻo i hana maʻamau ma o ka hoʻomaʻemaʻe ʻana i ka ʻaila bauxite.Loaʻa i ka pauka alumina nā ʻano waiwai i makemake ʻia, me ka paʻakikī kiʻekiʻe, ke kūpaʻa kemika, a me ka insulation uila, e lilo ia i mea waiwai i nā ʻoihana he nui.
