I nā noi wela kiʻekiʻe, he mea koʻikoʻi ke koho o nā mea. I waena o lākou, ua lilo ka reaction-sintered silicon carbide i mea koho kaulana ma muli o kāna hana maikaʻi loa. ʻO ka carbide silicon reaction-sintered he mea keramika i hoʻokumu ʻia e ka sintering hopena o ke kalapona a me ka pauka silika ma nā wela kiʻekiʻe.
ʻO ka mea mua, ʻoi aku ka maikaʻi o ke kūpaʻa wela kiʻekiʻe. Hiki iā ia ke mālama i kona ikaika mechanical a me ka paʻa kemika ma nā wela wela a hiki i 2,000 degere Celsius. ʻO kēia ka mea kūpono no nā noi wela kiʻekiʻe, e like me ka hoʻomaʻemaʻe ʻaila, ke kila a me nā ʻoihana ceramic.
ʻO ka lua, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka carbide silicon reaction-sintered. He kūʻē maikaʻi loa kēia mea a hiki ke noho paʻa no ka manawa lōʻihi i ka hakakā ʻino a me ka ʻaʻahu ʻana i nā kaiapuni. No laila, hoʻohana nui ʻia ia ma nā ʻano o ka wili, ʻoki a me nā mea hana abrasive.
Eia kekahi, ʻoi aku ka maikaʻi o ka conductivity thermal a me ka inertia kemika. Hiki iā ia ke alakaʻi wikiwiki i ka wela a hōʻike i ke kūpaʻa corrosion maikaʻi i nā wahi corrosive e like me ka waikawa a me ka alkali. Hoʻohana nui kēia i ka ʻoihana kemika a me ka hoʻokele wela.
Pono e hoʻomaopopo ʻia ʻo ke kaʻina hana hoʻomākaukau o ka reaction-sintered silicon carbide he mea paʻakikī, e koi ana i nā kūlana kiʻekiʻe kiʻekiʻe a me nā kūlana hopena kūikawā. Eia nō naʻe, me ka holomua mau o ka ʻenehana, ua hoʻomaikaʻi maikaʻi ʻia ke kaʻina hana, e hoʻemi mālie ana ke kumukūʻai o ka mea, a me ka hoʻolaha ʻana i kāna noi ākea ma nā ʻano ʻano like ʻole.
I ka hōʻuluʻulu ʻana, ma ke ʻano he mea wela kiʻekiʻe, reaction-sintered silicon carbide he koho maikaʻi loa ia no nā noi wela kiʻekiʻe ma muli o kona kūpaʻa kiʻekiʻe kiʻekiʻe, kūpaʻa ʻaʻahu, conductivity thermal a me ka inertia kemika. Ke hoʻomau nei ka hoʻomohala ʻana o ka ʻenehana, hiki iā mākou ke manaʻo e hoʻohana ʻia ka reaction-sintered silicon carbide i nā kula hou aʻe a me ka hoʻomaikaʻi ʻana i ka hana.
