I nā makahiki i hala iho nei, ua loaʻa mālie ka nānā ʻana a me ka hoʻohana ʻana i ka uhi ʻana o ka silicon carbide, ʻoi aku hoʻi i ke kiʻekiʻe o ka mahana, ke kaomi kiʻekiʻe, ke komo ʻana, ka pala a me nā kūlana hana ʻino ʻē aʻe, kahi i hiki ʻole ai i ka uhi silicone ke hoʻokō i nā koi i kekahi ʻano, ua lilo ka uhi ʻana o ka silicon carbide i koho kaulana o nā koho ʻē aʻe. ʻO ka uhi ʻana o ka silicon carbide, i ʻike ʻia hoʻi ʻo carbon silicide, he uhi pale ʻaʻahu i haku ʻia me ke kalapona a me ka silicon. No laila, he maikaʻi anei kēia uhi? E kamaʻilio kākou e pili ana i kā mākou hopena.
ʻO ka mea mua, ʻo kekahi o nā pono o ka uhi ʻana o ka silicon carbide, ʻo ia ka pale maikaʻi ʻana i ka ʻaʻahu. Ma nā kahua e like me nā kaʻa kaʻaahi wikiwiki, ka hana mīkini, ka hana ʻana i ka mold, ka aerospace a me ka hoʻokele, ʻo ka hoʻohana ʻana i ka paʻakikī o ka uhi ʻana o ka silicon carbide, ua hoʻomaikaʻi nui ʻia ke kūpaʻa ʻana i ka ʻaʻahu, no laila hiki ke hoʻomaikaʻi i ke ola lawelawe a me ke kūpaʻa o ka mea. No nā mīkini a me nā lako e pono ai ke holo no ka manawa lōʻihi, hiki i ka mea uhi kalapona silicified ke mālama i kekahi mau kumukūʻai, no ka mea hiki ke hōʻemi i ka ʻaʻahu a me ka waimaka o nā ʻāpana, hoʻolōʻihi i ke ola lawelawe o nā lako, a hōʻemi nui i nā kumukūʻai mālama.
ʻO ka lua, loaʻa i ka uhi silicon carbide kekahi kūpaʻa i ka pala a me ke kūpaʻa oxidation. I loko o nā ʻano waikawa, alkali a me nā mea ʻino ʻē aʻe a me nā kaiapuni oxidation wela kiʻekiʻe, ʻaʻole e ʻike ʻia ka uhi silicon carbide i ka pala a me ka oxidation, i mea e hōʻoia ai i ka hoʻohana ʻana i nā mea i uhi ʻia a me ka maikaʻi.
Eia kekahi, ikaika ka hoʻopili ʻana o ka uhi silicon carbide, hiki ke hoʻopaʻa pono ʻia i nā waiwai i uhi ʻia, i mea e hōʻoia ai i ke kūpaʻa a me ka hilinaʻi o ke ola lawelawe. Ma ke kahua hana ʻoihana a me ka hana ʻana, ma ke ʻano he ʻenehana uhi holomua, hiki iā ia ke hana hou i nā kiʻi paʻakikī loa a me nā ʻili pololei, i mea e hoʻokō ai i nā pono o ka nui o ka mānoanoa, ke ʻano kiʻekiʻe, a me nā koi kiʻekiʻe o nā huahana kūikawā.
ʻOiaʻiʻo, aia nā hemahema i ka uhi silicon carbide. ʻO ka mea mua, he kiʻekiʻe ke kumukūʻai hoʻomākaukau o ka uhi kalapona silicified, a ʻo ka hoʻohana ʻana iā ia e koi ana i ka ʻenehana kiʻekiʻe e pili ana, nā lako kiʻekiʻe a me ke kaʻina hana e hoʻopau ai i ka manawa, no laila he kiʻekiʻe kona kumukūʻai. ʻO ka lua, no ka mea ua hoʻokumu ʻia ka uhi kalapona silicified ma luna o ka ʻili o ka mea ma ke ʻano o ka hopena kemika, ua maʻalahi ka hoʻopilikia ʻia o kona mānoanoa a me ke ʻano like o ka kiʻiʻoniʻoni e nā mea he nui e like me ke kaʻina hana, nā mea laʻana a me ka nui, i hiki ʻole ke hoʻololi i kekahi mau kūlana kūikawā.
I ka hōʻuluʻulu manaʻo, ʻo ka uhi silicon carbide kekahi o nā uhi hana kiʻekiʻe a me nā hana he nui. Loaʻa iā ia nā pono o ke kūpaʻa ʻana i ka ʻaʻahu, ke kūpaʻa i ka pala, ka paʻakikī kiʻekiʻe, ke kūpaʻa ʻana i ka oxidation, ka hoʻopili ikaika a me nā ʻano ʻē aʻe, akā i ka manawa like, aia ke kumukūʻai hana kiʻekiʻe, ka mānoanoa o ka kiʻiʻoniʻoni like ʻole a me nā hemahema ʻē aʻe. Eia nō naʻe, i ka hoʻohālikelike ʻia me ka uhi kuʻuna, ua holomua nui ka uhi silicon carbide a ua hoʻonui mālie ʻia kona laulā noi. Me ka hoʻomohala mau ʻana a me ka hana hou ʻana o ka ʻenehana, ua manaʻoʻiʻo ʻia e hoʻopili ʻia ka uhi silicon carbide ma nā kahua he nui a hana i nā pono a me ka waiwai no nā kānaka.
