Hoʻohana ʻia nā koʻokoʻo Sapphire i nā ʻano hana like ʻole. Hiki ke hana ʻia kahi koʻokoʻo sapphire me nā ʻili āpau i hoʻopili ʻia no nā noi optical a me ke komo ʻana a i ʻole me nā ʻili āpau i wili maikaʻi ʻia (ʻaʻole i hoʻopili ʻia) e lawelawe ma ke ʻano he insulator.
ʻenehana
I ke kaʻina hana o ka huki ʻana i nā ʻōmole sapphire mai kahi heheʻe me ke kōkua o kahi hua, ʻo ka gradient mahana longitudinal ma ka ʻāpana ma waena o ke alo paʻa a me ka ʻāpana huki kahi i waena o 1850 a me 1900 deg. C e mālama ʻia ʻaʻole ʻoi aku ma mua o 30 deg. C/cm. Hoʻomehana ʻia ka ʻōmole i ulu ʻia ma kahi mahana ma waena o 1950 a me 2000 deg. C ma ka hoʻonui ʻana i ka mahana ma ka wikiwiki o 30 a 40 deg. C/min a mālama i ka ʻōmole ma ia mahana i loko o kahi manawa ma waena o 3 a me 4 mau hola. Ma hope o kēlā, hoʻomaʻalili ʻia ka ʻōmole i ka mahana o ka lumi ma ka wikiwiki o 30-40 deg. C/min.

ʻO ka mīkini sila paipu plasma kahi mea i hoʻohana ʻia e hoʻopuni i nā ʻāpana uila. ʻO kona kumu, ʻo ia ka hoʻohana ʻana i ke kiʻekiʻe o ka mahana a me ke kaomi kiʻekiʻe o ka plasma e hoʻoheheʻe i ka mea hoʻopili a hoʻopuni iā ia ma luna o ka ʻāpana. ʻO nā ʻāpana nui o ka mīkini sila paipu plasma e komo pū me ka mea hana plasma, ke keʻena sila paipu, ka ʻōnaehana vacuum, ka ʻōnaehana hoʻomalu, a me nā mea ʻē aʻe.
ʻO ka ʻūpā pale Thermocouple (Thermowell): ʻO Thermocouple kahi mea ana wela i hoʻohana pinepine ʻia i ka mea ana wela, ana pololei ia i ka mahana, a hoʻololi i ka hōʻailona mahana i ka hōʻailona ikaika electromotive thermoelectric, ma o ka mea uila (mea hana lua) i loko o ka mahana o ka medium i ana ʻia.
