ʻO ka pauka silicon carbide ʻōmaʻomaʻo a me ka pauka silicon carbide micropowder
ʻO Silicon carbide (SiC), i ʻike ʻia hoʻi ʻo carborundum, he semiconductor e loaʻa ana ka silicon a me ke kalapona me ke ʻano kemika SiC. Loaʻa ia ma ke ʻano he mineral moissanite kakaikahi loa. Ua hana nui ʻia ka pauka silicon carbide synthetic mai ka makahiki 1893 no ka hoʻohana ʻana ma ke ʻano he abrasive. Hiki ke hoʻopaʻa ʻia nā hua o ka silicon carbide ma o ka sintering e hana i nā keramika paʻakikī loa i hoʻohana nui ʻia i nā noi e koi ana i ke ahonui kiʻekiʻe, e like me nā paleki kaʻa, nā paʻa kaʻa a me nā papa keramika i loko o nā ʻaʻahu pale pōkā. Ua hōʻike mua ʻia nā noi uila o ka silicon carbide e like me nā diode hoʻomālamalama (LED) a me nā mea ʻike i nā lekiō mua ma kahi o 1907. Hoʻohana ʻia ʻo SiC i nā mea uila semiconductor e hana ana i nā mahana kiʻekiʻe a i ʻole nā voltage kiʻekiʻe, a i ʻole nā mea ʻelua. Hiki ke ulu ʻia nā kristal nui hoʻokahi o ka silicon carbide e ke ʻano Lely; hiki ke ʻoki ʻia i loko o nā pōhaku makamae i ʻike ʻia ʻo synthetic moissanite. Hiki ke hana ʻia ka Silicon carbide me ka ʻili kiʻekiʻe mai SiO2 i loko o nā mea kanu.

He kūpono ka silicon carbide ʻōmaʻomaʻo no ka hana ʻana i nā mea hao paʻakikī, nā mea metala a me nā mea ʻaʻole metala me nā hiʻohiʻona paʻakikī a palupalu e like me ke keleawe, ke keleawe, ka alumini, ka magnesium, ka momi, ke aniani optical, nā keramika, a pēlā aku. ʻO ka pauka super o ia mea he ʻano mea keramika nō hoʻi.

ʻO Shandong Zhongpeng Special Ceramics Co., Ltd kekahi o nā hoʻonā mea hou loa no ka silicon carbide ceramic ma Kina. ʻO ka keramika ʻenehana SiC: ʻO ka paʻakikī o Moh he 9 (ʻO ka paʻakikī o Moh hou he 13), me ke kūpaʻa maikaʻi loa i ka erosion a me ka corrosion, ke kūpaʻa abrasion maikaʻi loa a me ka anti-oxidation. ʻO ke ola lawelawe o ka huahana SiC he 4 a 5 mau manawa ka lōʻihi ma mua o 92% alumina mea. ʻO ka MOR o RBSiC he 5 a 7 mau manawa o SNBSC, hiki ke hoʻohana ʻia no nā ʻano paʻakikī. He wikiwiki ke kaʻina hana ʻōlelo, ʻo ka lawe ʻana e like me ka mea i hoʻohiki ʻia a ʻaʻohe lua o ka maikaʻi. Ke hoʻomau nei mākou i ka hoʻokūkū ʻana i kā mākou mau pahuhopu a hāʻawi i ko mākou mau naʻau i ke kaiāulu.
