Pilikia Puhi Alumina Puma Mamā

ʻO nā pōhaku lepo alumina kahi ʻano o nā mea hoʻōla wela wela a me nā mea hoʻoheheʻe wela. ʻO ka pōlele alumina he ʻano hou o nā mea hoʻoheheʻe wela wela kiʻekiʻe. Hana ʻia lākou me ka alumina ʻoihana ma ka hoʻoheheʻe ʻana a me ka puhi ʻana i kahi umu uila, a ʻo ke ʻano aniani he microcrystals a-Al2O3. Me nā kinipōpō alumina e like me ke kino nui, hiki ke hana ʻia nā huahana o nā ʻano like ʻole, me ka mahana hana kiʻekiʻe o 1800 ℃. Loaʻa ka ikaika mechanical kiʻekiʻe o nā huahana, ʻoi aku ka nui o nā huahana māmā maʻamau, a ʻo ka hapa nui o ka nui o nā huahana corundum. Ua hoʻohana nui ʻia i nā kiln kiʻekiʻe a me ka ultra-kiʻekiʻe e like me ka petrochemical ʻoihana gasification furnaces, carbon black industrial reactors, a me ka metallurgical industry induction furnaces, a ua loaʻa i nā hopena hoʻopakele ikehu.
