ʻO ka waʻaʻeleʻele Silicon carbide kahi mea me nā waiwai maikaʻi loa, e hōʻike ana i ka wela a me ka pale ʻana i ka corrosion i nā wahi wela kiʻekiʻe. He hui ia me nā mea kalapona a me ke silika me ka paʻakikī kiʻekiʻe, ka helu heheʻe kiʻekiʻe a me ka conductivity thermal maikaʻi loa. ʻO kēia ka mea i kūpono i nā waʻa kristal carbide silicon no nā ʻano noi wela kiʻekiʻe, e like me ka aerospace, ka ikehu nuklea, kemika, etc.
ʻO ka mea mua, ʻoi aku ka maikaʻi o ke kūpaʻa wela o ka moku silicon carbide crystal i nā wahi wela kiʻekiʻe. Ma muli o kona ʻano ʻano aniani kūikawā, hiki i ka moku aniani carbide silicon ke mālama i kona mau kino kino a me nā mea kemika ma lalo o nā kūlana wela. Hiki iā ia ke pale i nā mahana a hiki i ka 1500 degrees Celsius me ka ʻole o ka deformation a i ʻole rupture, e hoʻohana nui ʻia i ka hoʻoheheʻe wela kiʻekiʻe, ka hopena wela kiʻekiʻe a me nā kaʻina hana ʻē aʻe.
ʻO ka lua, ʻoi aku ka maikaʻi o ke kūpaʻa corrosion o ka moku silicon carbide kristal i ke kiʻekiʻe wela. I kekahi mau wahi kemika koʻikoʻi, nui nā metala a me nā mea ʻē aʻe e hoʻopilikia ʻia e ka corrosion, akā hiki i ka moku aniani carbide silicon ke mālama i kona kūpaʻa. ʻAʻole ia e ʻino ʻia e ka waikawa, alkali a me nā mea corrosive ʻē aʻe, e hoʻohana nui ʻia i nā kemika, uila a me nā ʻoihana ʻē aʻe.
Eia kekahi, ʻo ka conductivity thermal o ka moku aniani carbide silicon kekahi o kāna mau pono. Ma muli o kona ʻano ʻano aniani kū hoʻokahi, he kiʻekiʻe kiʻekiʻe ka hoʻoili ʻana o ka pahu silicon carbide crystal a hiki iā ia ke lawe koke i ka wela a mālama i ka hāʻawi ʻana o ka mahana. Hoʻohana nui kēia i ka mālama wela, ka hana semiconductor a me nā māla ʻē aʻe.
I ka pōkole, silicon carbide crystal waʻa me kona maikaʻi wela kū'ē, corrosion kū'ē a me thermal conductivity, lilo i ka mea kūpono i ka kiʻekiʻe wela kaiapuni. Loaʻa iā ia ka laulā o nā noi, hiki ke hoʻokō i nā pono o nā kaʻina hana wela kiʻekiʻe, a loaʻa ka mana nui i ka hoʻomohala e hiki mai ana.
