Kugwiritsa Ntchito Kwambiri Kwa Silicon Carbide

Black silicon carbide imapangidwa kuchokera ku mchenga wa quartz ndi petroleum coke silica monga zida zazikulu zopangira kudzera pakutentha kwambiri kusungunula mung'anjo yotsutsa. Kulimba kwake kuli pakati pa corundum ndi diamondi, mphamvu zake zamakina ndizokwera kuposa corundum, ndipo ndizovuta komanso zakuthwa. Green silicon carbide imapangidwa kuchokera ku petroleum coke ndi silika monga zida zazikulu zopangira, zokhala ndi mchere wowonjezera ngati chowonjezera, ndikusungunulidwa pa kutentha kwakukulu mu ng'anjo yotsutsa. Kuuma kwake kuli pakati pa corundum ndi diamondi, ndipo mphamvu yake yamakina ndi yapamwamba kuposa corundum.

Ndiye ntchito zazikulu za silicon carbide ndi ziti?
1. Abrasives - Makamaka chifukwa silicon carbide imakhala yolimba kwambiri, kukhazikika kwa mankhwala ndi kulimba kwina, silicon carbide ingagwiritsidwe ntchito kupanga zomangira zomangira, zomatira zomatira ndi kugaya kwaulere pokonza magalasi ndi zoumba. , mwala, chitsulo chosungunula ndi zitsulo zina zopanda chitsulo, carbide, titaniyamu aloyi, zida zodulira zitsulo zothamanga kwambiri ndi mawilo opera, etc.

2. Zida zokanira ndi zinthu zosagwira dzimbiri --- Makamaka chifukwa silicon carbide imakhala ndi malo osungunuka kwambiri (degree of decomposition), inertness ya mankhwala ndi kutentha kwa kutentha, silicon carbide ingagwiritsidwe ntchito mu abrasives ndi ceramic product fire fire kilns. Ma mbale okhetsa ndi ma sagger, njerwa za silicon carbide zopangira ng'anjo zoyimirira za silinda m'makampani osungunula zinc, aluminium electrolytic cell linings, crucibles, zida zazing'ono zowotcha ndi zinthu zina za silicon carbide ceramic.

3. Mankhwala amagwiritsira ntchito-chifukwa silicon carbide imatha kuwola muzitsulo zosungunuka ndikuchitapo kanthu ndi okosijeni ndi zitsulo zazitsulo muzitsulo zosungunuka kuti apange carbon monoxide ndi silicon-containing slag. Chifukwa chake, itha kugwiritsidwa ntchito ngati choyeretsera pakusungunula zitsulo, ndiye kuti, ngati deoxidizer komanso chowongolera chachitsulo chopangira zitsulo. Izi nthawi zambiri amagwiritsa ntchito otsika chiyero silicon carbide kuchepetsa ndalama. Itha kugwiritsidwanso ntchito ngati zopangira zopangira silicon tetrachloride.

4. Ntchito zamagetsi - zomwe zimagwiritsidwa ntchito ngati zinthu zotenthetsera, zosakanizidwa zopanda mzere ndi zida zapamwamba za semiconductor. Zinthu zotenthetsera monga silicon carbon rods (zoyenera ng'anjo zamagetsi zosiyanasiyana zomwe zimagwira ntchito pa 1100 mpaka 1500 ° C), zinthu zopanda mzere, ndi mavavu osiyanasiyana oteteza mphezi.
