ʻO ka alumina ceramics kahi ʻano mea hana seramika me Al2O3 ma ke ʻano he kumu nui a me ka corundum (a-Al2O3) ma ke ʻano he crystalline nui. ʻOi aku ka kiʻekiʻe o ka hoʻoheheʻe ʻana o ka alumina ceramics ma muli o ka helu heheʻe o ka alumina e like me ke kiʻekiʻe o 2050 C, ʻo ia ka mea e pono ai ka hana ʻana o nā alumina ceramics e hoʻohana i ka mea wela wela a i ʻole nā mea kiʻekiʻe kiʻekiʻe a me nā refractory kiʻekiʻe e like me ke kiln a me nā lako kiln. , ka mea i kaupalena 'ia kona hana a me ka hoʻohana ākea. No laila he aha kāna mau mea maikaʻi?
He nui nā pono o ka alumina ceramics, e like me ka ikaika mechanical kiʻekiʻe, ka paʻakikī kiʻekiʻe, ka nalowale o ka dielectric haʻahaʻa i nā alapine kiʻekiʻe, a ma muli o kāna kumu ākea o nā mea maka, ke kumu kūʻai maʻalahi a me ka ʻenehana hoʻoponopono makua, ua hoʻohana nui ʻia ia i ka ʻoihana uila. nā mea uila, nā mīkini, nā lole a me nā aerospace. Ua hoʻokumu pū i kona kūlana kiʻekiʻe ma ke kahua o nā mea seramika. Ua hōʻike ʻia ʻo ka alumina ceramics ka mea i hoʻohana nui ʻia i ka oxide ceramics ma ka honua.
