ʻO ke kīʻaha silika carbideua hana ʻia me ka silicon carbide mea a he ipu wela kiʻekiʻe.ʻO ke kīʻaha silika carbideLoaʻa i ka paʻa wela kiʻekiʻe, maikaʻi ke kūpaʻa corrosion a me ka hoʻonui haʻahaʻa haʻahaʻa haʻahaʻa, e hiki ai iā ia ke pale i ke koʻikoʻi wela a me ka hoʻoneʻe kemika i nā kaiapuni kiʻekiʻe. Hoʻohana ʻia ia no ka noho ʻana a me ka hana ʻana i nā hoʻokolohua a i ʻole nā kaʻina hana ʻenehana e like me ka hoʻoheheʻe ʻana, sintering, mālama wela a me nā hopena kemika ma lalo o nā kūlana kiʻekiʻe.
ʻO kā mākoukīʻaha kalapona silikahana ʻia e ke kaomi isostatic maʻemaʻe kiʻekiʻe a loaʻa ka conductivity thermal maikaʻi a me ke kūpaʻa wela kiʻekiʻe. I ke kaʻina hana o ka hoʻohana wela kiʻekiʻe, he liʻiliʻi ka coefficient o ka hoʻonui ʻana i ka wela, a loaʻa iā ia kahi kūpaʻa kūʻē i ka hoʻomehana a me ka hoʻoilo. Loaʻa iā ia ke kūpaʻa corrosion ikaika i ka waika a me ka hopena alkali a me ke kūpaʻa kemika maikaʻi loa. Hiki ke hoʻopilikino ʻia ke kŘkohu kiko'ī ma ke kaha kiʻi ʻana a me ka laʻana, a ʻo ka mea he graphite home a me ka graphite lawe ʻia mai e hoʻokō i nā pono like ʻole o nā mea kūʻai aku.
ʻO nā mea waiwai nui o ka graphite crucible he graphite, silicon carbide, silica, refractory clay, pitch, a me ka tar, etc.
