Me ka hana nui mālie o nā substrates SiC conductive, ua kau ʻia nā koi kiʻekiʻe no ke kūpaʻa a me ka hana hou ʻana o ke kaʻina hana. ʻO ka mea nui, ʻo ka kaohi ʻana i nā hemahema, ka hoʻoponopono liʻiliʻi a i ʻole ka neʻe ʻana o ke kahua wela i loko o ka umu, e lawe mai i nā loli kristal a i ʻole ka hoʻonui ʻana o nā hemahema. I ka wā ma hope, pono mākou e kū i ka pilikia o ka "ulu wikiwiki, lōʻihi a mānoanoa, a ulu aʻe", me ka hoʻomaikaʻi ʻana i ke kumumanaʻo a me ka ʻenekinia, pono mākou i nā mea kahua wela holomua e like me ke kākoʻo. E hoʻohana i nā mea holomua, e ulu i nā kristal holomua.
ʻO ka hoʻohana pono ʻole ʻana i nā mea ipu hoʻoheheʻe, e like me ka graphite, porous graphite, tantalum carbide powder, a pēlā aku i ke kahua wela e alakaʻi i nā hemahema e like me ka hoʻonui ʻia o 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 ke kiʻekiʻe permeability e kū nei i nā pilikia o ka hana ʻana, ka wehe ʻana i ka pauka, ka etching a pēlā aku.
Hoʻolauna ʻo VET i kahi hanauna hou o ka mea ulu wela kristal SiC, ʻo ia hoʻi ka porous tantalum carbide. He hoʻomaka mua honua.
He kiʻekiʻe loa ka ikaika a me ka paʻakikī o ka tantalum carbide, a he paʻakikī ka hana ʻana iā ia he porous. He paʻakikī nui ka hana ʻana i ka porous tantalum carbide me ka porosity nui a me ka maʻemaʻe kiʻekiʻe. Ua hoʻokuʻu ʻo Hengpu Technology i kahi holomua porous tantalum carbide me ka porosity nui, me ka porosity kiʻekiʻe o 75%, e alakaʻi ana i ka honua.
Hiki ke hoʻohana ʻia ka kānana ʻāpana kinoea, ka hoʻoponopono ʻana i ka gradient mahana kūloko, ke kuhikuhi o ke kahe ʻana o nā mea, ka kaohi ʻana i ka leakage, a me nā mea ʻē aʻe. Hiki ke hoʻohana ʻia me kahi uhi tantalum carbide paʻa ʻē aʻe (compact) a i ʻole ka uhi tantalum carbide mai Hengpu Technology e hana i nā ʻāpana kūloko me nā conductance kahe like ʻole.
Hiki ke hoʻohana hou ʻia kekahi mau ʻāpana.
