Me ka hana lohi ʻana o nā substrates SiC conductive, ua kau ʻia nā koi kiʻekiʻe no ka kūpaʻa a me ka hana hou ʻana o ke kaʻina hana. ʻO ka mea nui, ʻo ka mālama ʻana i nā hemahema, ka hoʻololi liʻiliʻi a i ʻole ka neʻe ʻana o ke kahua wela i ka umu, e lawe mai i nā loli aniani a i ʻole ka piʻi ʻana o nā hemahema. I ka wā ma hope, pono mākou e kū i ka paʻakikī o ka "ulu wikiwiki, lōʻihi a mānoanoa, a me ka ulu ʻana", ma kahi o ka hoʻomaikaʻi ʻana i ke kumumanaʻo a me ka ʻenekinia, pono mākou i ʻoi aku ka maikaʻi o nā lako kahua wela e like me ke kākoʻo. E hoʻohana i nā mea kiʻekiʻe, e ulu i nā kristal holomua.
ʻO ka hoʻohana pono ʻole ʻana i nā mea crucible, e like me ka graphite, porous graphite, tantalum carbide pauka, a me nā mea ʻē aʻe i ke kahua wela e alakaʻi i nā hemahema e like me ka hoʻonui ʻana i ke kalapona. Eia kekahi, i kekahi mau noi, ʻaʻole lawa ka permeability o ka porous graphite, a pono nā lua hou e hoʻonui i ka permeability. ʻO ka porous graphite me ka permeability kiʻekiʻe ke kū nei i nā pilikia o ka hana ʻana, ka wehe ʻana i ka pauka, etching a pēlā aku.
Hoʻolauna ʻo VET i kahi hanauna hou o ka SiC crystal e ulu ana i nā mea wela wela, porous tantalum carbide. He hoʻomaka honua.
ʻO ka ikaika a me ka paʻakikī o ka tantalum carbide he kiʻekiʻe loa, a he paʻakikī ka hana ʻana i ka porous. He paʻakikī nui ka hana ʻana i ka tantalum carbide me ka porosity nui a me ka maʻemaʻe kiʻekiʻe. Ua hoʻokumu ʻo Hengpu Technology i kahi breakthrough porous tantalum carbide me ka porosity nui, me ka porosity kiʻekiʻe o 75%, alakaʻi i ka honua.
Hiki ke hoʻohana i ka kānana ʻāpana kinoea, ka hoʻoponopono ʻana i ka gradient wela kūloko, ke kuhikuhi o ke kahe waiwai, ka hoʻomalu ʻana i ka leakage, etc. Hiki ke hoʻohana ʻia me kahi carbide tantalum paʻa ʻē aʻe (compact) a i ʻole ka tantalum carbide coating mai Hengpu Technology e hana i nā ʻāpana kūloko me nā conductance kahe like ʻole.
Hiki ke hoʻohana hou ʻia kekahi mau mea.
