ʻO ka Sapphire i hoʻonohonoho pono ʻia i ka hale hana
ʻO ka Sapphire ka paʻakikī o Mohs 9, ka lua wale nō i ke daimana, a he kūpaʻa maikaʻi kona ʻaʻahu. I ka manawa like, loaʻa iā ia ka paʻa kemika maikaʻi loa a hiki ke pale aku i ka ʻino o kahi kokoke i nā mea waikawa a me nā alkali. Eia kekahi, ʻo ka pale wela kiʻekiʻe o ka sapphire he 2060 ℃. Ma muli o nā pono o luna o ka sapphire, hoʻohana ʻia ka sapphire i nā mea kani a me nā mea hana, hiki ke hoʻomaikaʻi maikaʻi i ke ola lawelawe a kū i nā ʻano ʻino.
Loaʻa pinepine nā ʻāpana kiko Sapphire i nā koi ʻano paʻakikī a me nā koi hoʻopaʻa paʻa. Hiki iā mākou ke hana i nā ʻano like ʻole e like me nā kaha kiʻi a nā mea kūʻai aku. Loaʻa iā mākou ka ʻoki pololei, ka wili, ka polishing a me ka hoʻāʻo ʻana e hōʻoia i kēlā me kēia huahana e hoʻokō i nā koi koʻikoʻi o nā mea kūʻai.

Mea Pono
ʻO ka Sapphire kahi aniani alumini oxide (Al2O3). ʻO ia kekahi o nā mea paʻakikī loa. Loaʻa i ka Sapphire nā hiʻohiʻona hoʻoili maikaʻi ma luna o ka mea i ʻike ʻia, a kokoke i ka spectrum IR. Hōʻike ia i ka ikaika mechanical kiʻekiʻe, ke kūpaʻa kemika, ka conductivity thermal a me ke kūpaʻa wela. Hoʻohana pinepine ʻia ʻo ia e like me nā mea puka makani ma ke kahua kikoʻī e like me ka ʻenehana ākea kahi e koi ʻia ai ke kūʻē ʻana a i ʻole ka wela wela.
