chitsulo cha silicon carbide

Silicon Carbide Metal: A Comprehensive GuideSilicon carbide (SiC) ndi chinthu chodabwitsa chomwe chili ndi ntchito zosiyanasiyana, zomwe nthawi zambiri zimatchedwa chitsulo cha silicon carbide, ngakhale mwaukadaulo ndi ceramic. Bukuli likufotokoza za katundu, njira zopangira, ndi kagwiritsidwe ntchito kosiyanasiyana kwa zinthu zolimbazi.

Kumvetsetsa Silicon Carbide

Katundu wa Silicon Carbide Metal

Silicon carbide chitsulo, yomwe imadziwikanso kuti carborundum, imakhala yolimba kwambiri, yachiwiri pambuyo pa diamondi. Kuuma kopitilira muyesoku, kuphatikizidwa ndi matenthedwe apamwamba kwambiri, kusakhazikika kwamankhwala, komanso kulimba kwamphamvu, kumapangitsa kukhala koyenera pakufunsira ntchito. Malo ake osungunuka kwambiri (mozungulira 2730 ° C) amathandiziranso kuti akhale oyenerera malo otentha kwambiri. Mapangidwe apadera a kristalo a SiC amabweretsa ma polymorphs osiyanasiyana, chilichonse chikuwonetsa zinthu zosiyana pang'ono, zomwe zimatsogolera kukugwiritsa ntchito molingana ndi mtundu wa SiC womwe umagwiritsidwa ntchito. Zinthu izi zimapangitsa kuti zikhale zoyenera kwa ogwiritsa ntchito osiyanasiyana m'mafakitale angapo.

Njira Zopangira

Kupanga kwa chitsulo cha silicon carbide imaphatikizapo njira zingapo, makamaka njira ya Acheson, yomwe imagwiritsa ntchito kutentha kwambiri kuti iwononge silica (SiO2) ndi carbon (C) mu ng'anjo yamagetsi yamagetsi. Njira zina zimaphatikizirapo mankhwala a vapor deposition (CVD) ndi njira zowonongeka kwambiri zomwe zimalola kupanga makristasi apamwamba a SiC omwe amagwiritsidwa ntchito pa ntchito zapamwamba. Njira yeniyeni yomwe imagwiritsidwa ntchito imadalira chiyero chomwe chimafunidwa ndi mawonekedwe a kristalo wa chinthu chomaliza, zomwe zimakhudza zinthu monga mtengo ndi kugwiritsa ntchito.

Mapulogalamu a Silicon Carbide Metal

Industrial Applications

Gawo la mafakitale limagwiritsa ntchito kwambiri chitsulo cha silicon carbide m'mapulogalamu ambiri. Kulimba kwake kumapangitsa kuti ikhale chinthu chofunikira kwambiri pazida zopukutira, mawilo opera, ndi zida zodulira. Kusakhazikika kwamankhwala ndikofunikira kwambiri pamachitidwe monga ma crucibles otentha kwambiri ndi ma linings a ma reactor amankhwala. Kuphatikiza apo, kuthekera kwake kupirira mikhalidwe yoipitsitsa kumagwiritsidwa ntchito m'njira zosiyanasiyana zamafakitale pomwe kulimba ndi kukana ndikofunikira.

Mapulogalamu Amagetsi

Kupita patsogolo kwaposachedwa chitsulo cha silicon carbide wofunikira kwambiri pamakampani opanga zamagetsi. Zamagetsi zapadera za SiC zimalola kupanga zida zamphamvu kwambiri, zothamanga kwambiri monga ma transistors ndi ma diode. Zigawozi ndizofunika kwambiri pamagetsi amagetsi, zomwe zimapereka ubwino wambiri pakuchita bwino ndi ntchito poyerekeza ndi zida zachikhalidwe za silicon. Izi zimapangitsa SiC kukhala yofunika kwambiri pamagwiritsidwe ntchito ngati magalimoto amagetsi, magetsi ongowonjezwdwanso, ndi zida zamafakitale zamphamvu kwambiri. Malingaliro a kampani Inner Mongolia Xinxin Silicon Industry Co., Ltd.https://www.xinxinsilicon.com/) ndi chitsanzo chotsogola cha kampani yomwe ikukhudzidwa ndi kupanga ndi kupereka zida zapamwamba za SiC zogwiritsira ntchito.

Mapulogalamu Ena

Kupitilira kugwiritsa ntchito mafakitale ndi zamagetsi, chitsulo cha silicon carbide imapeza njira zake m'magawo ena osiyanasiyana. Biocompatibility yake imapangitsa kuti ikhale yoyenera pazinthu zina zamankhwala, pomwe kukana kwake kutentha ndi mphamvu zimayendetsedwa ndi kutentha kwakukulu monga zida zotsutsa ndi zokutira zoteteza.

Kuyerekeza SiC ndi Zida Zina

Gome lotsatirali likufanizira chitsulo cha silicon carbide ndi zinthu zina wamba:

Katundu	Silicon Carbide	Aluminium oxide	Tungsten Carbide
Kulimba (Mohs sikelo)	9.5	9	9-10
Thermal Conductivity (W/mK)	120-390	30-40	50-60
Malo osungunuka (°C)	~ 2730	2050	~ 2870

Mapeto

Silicon carbide chitsulo ndi zinthu zosunthika komanso zogwira ntchito kwambiri zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Kuphatikiza kwake kwapadera kwazinthu kumapangitsa kuti ikhale yofunikira pakupita patsogolo kwaukadaulo wambiri komanso njira zama mafakitale. Pamene kafukufuku akupitilira komanso njira zopangira zinthu zikuyenda bwino, tsogolo limakhala ndi kuthekera kokulirapo kwa zinthu zochititsa chidwizi.Zindikirani: Zomwe zili mu tebulo ili pamwambazi ndizoyerekeza ndipo zingasiyane malinga ndi kalasi yeniyeni ndi njira yopangira. Zambiri zokhudzana ndi zida zosiyanasiyana za SiC zitha kupezeka kudzera m'mabuku asayansi ndi zolemba zakuthupi kuchokera kwa ogulitsa ngati Inner Mongolia Xinxin Silicon Viwanda Co., Ltd.
