Kushandiswa Kwakanyanya KweSilicon Carbide

Black silicon carbide inogadzirwa kubva kujecha requartz uye petroleum coke silica semidziyo mikuru kuburikidza nekunyungudika kwepamusoro-tembiricha muvira rekudzivirira. Kuoma kwayo kuri pakati pecorundum nedhaimani, simba rayo remuchina rakakwirira kudarika corundum, uye ine brittle uye inopinza. Green silicon carbide inogadzirwa kubva petroleum coke uye silica seyakanyanya mbishi zvinhu, ine munyu wakawedzerwa sekuwedzera, uye yakanyungudutswa pakupisa kwakanyanya muchoto chekudzivirira. Kuoma kwayo kuri pakati pe corundum nedhaimani, uye simba rayo remagetsi rakakwirira kudarika corundum.

Saka ndezvipi zvakanyanya kushandiswa kwesilicon carbide?
1. Abrasives - Kunyanya nokuti silicon carbide ine kuoma kwepamusoro, kugadzikana kwemakemikari uye kumwe kuoma, silicon carbide inogona kushandiswa kugadzira mabrasives akasungwa, akavharidzirwa abrasives uye kusununguka kusununguka kugadzira girazi uye ceramics. , dombo, simbi yakakandwa uye mamwe masimbi asina-ferrous, carbide, titanium alloy, high-speed simbi yekucheka maturusi uye mavhiri ekukuya, nezvimwewo.

2. Refractory materials and corrosion-resistant materials---Kunyanya nokuti silicon carbide ine nzvimbo yakanyanyisa kunyunguduka (degree of decomposition), makemikari inertness uye thermal shock resistance, silicon carbide inogona kushandiswa mumabrasives uye ceramic product firing kilns. Shed mahwendefa uye saggers, silicon carbide zvidhinha zve vertical cylinder distillation mavira mune zinc smelting indasitiri, aluminium electrolytic cell linings, crucibles, zvidiki zvevira uye zvimwe silicon carbide ceramic zvigadzirwa.

3. Kemikari inoshandiswa-nekuti silicon carbide inogona kuora musimbi yakanyungudutswa uye inopindirana neoxygen uye metal oxides musimbi yakanyungudutswa kuti ibudise carbon monoxide nesilicon-containing slag. Nokudaro, inogona kushandiswa sechinhu chekuchenesa chekunyungudutsa simbi, kureva, se deoxidizer uye simbi yakakandwa inovandudza kugadzira simbi. Izvi zvinowanzoshandisa yakaderera kuchena silicon carbide kuderedza mutengo. Inogona zvakare kushandiswa seyakagadzirwa zvinhu zvekugadzira silicon tetrachloride.

4. Mashandisirwo emagetsi - anoshandiswa sezvinhu zvinopisa, zvisiri-mutsara zvinopikisa zvinhu uye yakakwirira semiconductor zvinhu. Zvinhu zvekudziisa zvakaita sesilicon carbon rods (zvinokodzera mafito emagetsi akasiyana siyana anoshanda pa1100 kusvika 1500 ° C), zvisiri-mutsara resistor elements, uye mavharuvhu ekudzivirira mheni akasiyana.
