ʻO ka pauda kalapona silika ʻōmaʻomaʻo a me ka pauda ʻeleʻele silika

ʻO Silicon carbide (SiC), i ʻike ʻia ʻo carborundum, he semiconductor i loaʻa ke silikoni a me ke kalapona me ke ʻano kemika SiC. Loaʻa ia ma ke ʻano e like me ka moissanite mineral loaʻa loa. Ua hana nui ʻia ka pauka silicon carbide mai ka makahiki 1893 no ka hoʻohana ʻana ma ke ʻano he abrasive. Hiki ke hoʻopaʻa ʻia nā ʻāpana o ka silicon carbide ma o ka sintering e hana i nā seramika paʻakikī loa i hoʻohana nui ʻia i nā noi e koi ana i ka hoʻomanawanui kiʻekiʻe, e like me nā kaʻa kaʻa, nā kaʻa kaʻa a me nā papa seramika i loko o nā lole pale pale. Ua hōʻike mua ʻia nā noi uila o ka silicon carbide e like me nā kukui-emitting diodes (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 wela kiʻekiʻe a i ʻole nā ​​​​volta kiʻekiʻe, a i ʻole nā ​​​​mea ʻelua. Hiki ke hoʻoulu ʻia nā kristal nui hoʻokahi o ka silicon carbide ma ke ʻano Lely; hiki ke ʻoki ʻia i loko o nā pōhaku i kapa ʻia ʻo synthetic moissanite. Hiki ke hana ʻia ka silikoni carbide me ka ʻili kiʻekiʻe mai SiO2 i loko o nā mea kanu.

Hōʻike huahana

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