Genellikle \"karborundum\" ticari ad\u0131yla an\u0131lan SiC, ayn\u0131 zamanda \u00e7ok nadir bulunan mozanit minerali olarak da do\u011fal olarak bulunur.<\/p>\n
PEEK, g\u00fc\u00e7 kaynaklar\u0131 gibi y\u00fcksek s\u0131cakl\u0131klarda ve voltajlarda \u00e7al\u0131\u015fan elektronik cihazlarda kullan\u0131l\u0131r. Ayr\u0131ca, elektrikli ara\u00e7larda \u00f6nemli bir malzemedir; daha uzun batarya \u00f6mr\u00fc ve daha y\u00fcksek g\u00fc\u00e7 verimlili\u011fi sayesinde s\u00fcr\u00fc\u015f menzilini art\u0131r\u0131r ve g\u00fc\u00e7 verimlili\u011fini iyile\u015ftirir.<\/p>\n
Daha yayg\u0131n olarak SiC olarak adland\u0131r\u0131lan silisyum karb\u00fcr, genellikle meteoritlerde ve nadir mineral mozanitte bulunan son derece a\u015f\u0131nd\u0131r\u0131c\u0131 bir malzemedir. Tamamen silikon ve karbondan olu\u015fan SiC, n tipi yar\u0131 iletken olarak kullan\u0131lmak \u00fczere nitrojen veya fosforla ya da p tipi yar\u0131 iletken uygulamalar\u0131 i\u00e7in al\u00fcminyum, bor veya galyumla katk\u0131lanabilir. End\u00fcstriyel z\u0131mpara ka\u011f\u0131d\u0131 genellikle bile\u015fenlerinden biri olarak SiC i\u00e7erirken, jilet keskinli\u011findeki taneleri metal, cam, mermer mantar ta\u015f\u0131 orta yo\u011funlukta lif levhay\u0131 h\u0131zl\u0131 a\u015f\u0131nd\u0131r\u0131c\u0131 kullan\u0131m i\u00e7in zahmetsizce z\u0131mparalayabilir - a\u015f\u0131nd\u0131r\u0131c\u0131 malzeme olarak kullan\u0131m i\u00e7in m\u00fckemmel!<\/p>\n
Al\u00fcminyum, g\u00fc\u00e7l\u00fc kimyasal \u00f6zellikler, termal iletkenlik, d\u00fc\u015f\u00fck genle\u015fme katsay\u0131s\u0131 ve a\u015f\u0131nma direnci gerektiren y\u00fcksek performansl\u0131 uygulamalar i\u00e7in ideal bir malzeme se\u00e7imidir. Bu \u00e7ok y\u00f6nl\u00fc metal, sertli\u011fi nedeniyle a\u015f\u0131nd\u0131r\u0131c\u0131lar, a\u015f\u0131nmaya dayan\u0131kl\u0131 par\u00e7alar ve refrakterler; kararl\u0131l\u0131\u011f\u0131 ve g\u00fcvenilirli\u011fi nedeniyle elektronikler ve \u0131s\u0131 direnci nedeniyle metalurjik uygulamalar gibi uygulamalarda bulunabilir.<\/p>\n
Silisyum karb\u00fcr\u00fcn benzersiz mekanik ve kimyasal \u00f6zellikleri onu pompa yataklar\u0131, valfler, kumlama enjekt\u00f6rleri, ekstr\u00fczyon kal\u0131plar\u0131, dayan\u0131kl\u0131l\u0131k korozyon direnci ve y\u00fcksek erime noktas\u0131 gibi y\u00fcksek performansl\u0131 m\u00fchendislik uygulamalar\u0131 i\u00e7in m\u00fckemmel bir malzeme se\u00e7imi haline getirmektedir. A\u011f\u0131r toprak zemini, hafif toprak ko\u015fullar\u0131na k\u0131yasla y\u00fczeyinde daha az s\u00fcrt\u00fcnme olu\u015fturabilirken, silisyum karb\u00fcr tozu insanlarda ilerleyici olmayan pulmoner fibrozise neden olabilir.<\/p>\n
Daha yayg\u0131n olarak karborundum olarak adland\u0131r\u0131lan silisyum karb\u00fcr, 19. y\u00fczy\u0131l\u0131n sonlar\u0131nda kullan\u0131lmaya ba\u015flanmas\u0131ndan bu yana a\u015f\u0131nd\u0131r\u0131c\u0131 bir malzeme olarak uzun s\u00fcredir kullan\u0131lan ola\u011fan\u00fcst\u00fc sert kristalli bir silikon ve karbon bile\u015fi\u011fidir.

Silisyum karb\u00fcr, standart silikon yar\u0131 iletkenlerden \u00fc\u00e7 kat daha b\u00fcy\u00fck bir bant aral\u0131\u011f\u0131na sahip oksit olmayan bir seramiktir, bu da daha y\u00fcksek voltajlara dayanabilece\u011fi anlam\u0131na gelir. Ayr\u0131ca, sinterleme i\u015flemi elektronik devrelere zarar verme olas\u0131l\u0131\u011f\u0131 daha d\u00fc\u015f\u00fck olan \u00e7ok k\u00fc\u00e7\u00fck par\u00e7ac\u0131klar \u00fcretir. Bor ve al\u00fcminyum gibi katk\u0131 maddeleri eklendi\u011finde, silisyum karb\u00fcr p-tipi bir yar\u0131 iletken haline gelir; bunun yerine fosfor ve nitrojen katk\u0131s\u0131 eklendi\u011finde n-tipi bir yar\u0131 iletkene d\u00f6n\u00fc\u015f\u00fcr.<\/p>\n
Silisyum karb\u00fcr sinterleme, ola\u011fan\u00fcst\u00fc mekanik \u00f6zelliklere sahip yo\u011fun \u00fcr\u00fcnler \u00fcreten kolay bir i\u015flemdir. Sertli\u011fi, ta\u015flama, su jeti ile kesme ve kumlama gibi bir\u00e7ok a\u015f\u0131nd\u0131r\u0131c\u0131 i\u015fleme prosesi i\u00e7in kritik \u00f6neme sahiptir; modern ta\u015f ustalar\u0131 da silisyum karb\u00fcr\u00fcn dayan\u0131kl\u0131l\u0131\u011f\u0131na ve y\u00fcksek boyutsal kararl\u0131l\u0131\u011f\u0131na de\u011fer verir; spor arabalar veya di\u011fer performans ara\u00e7lar\u0131 i\u00e7in y\u00fcksek performansl\u0131 fren diskleri \u00fcretmek i\u00e7in bile kullan\u0131labilir.<\/p>\n
Silisyum karb\u00fcr veya SiC, sertli\u011fi nedeniyle a\u015f\u0131nd\u0131r\u0131c\u0131lar ve a\u015f\u0131nmaya dayan\u0131kl\u0131 par\u00e7alardan; \u0131s\u0131 direnci ve termal genle\u015fmesi nedeniyle metalurji ve refrakterlere; voltaj dayan\u0131m\u0131 \u00f6zellikleri nedeniyle g\u00fc\u00e7 elektroni\u011fi uygulamalar\u0131na kadar \u00e7e\u015fitli uygulamalarda kullan\u0131m alan\u0131 bulan oksit olmayan seramik bir malzemedir; n-tipi yar\u0131 iletkenler olu\u015fturmak i\u00e7in azot veya fosfor katk\u0131l\u0131 veya p-tipi yar\u0131 iletkenler olu\u015fturmak i\u00e7in berilyum, bor ve al\u00fcminyum katk\u0131l\u0131; yak\u0131n paketlenmi\u015f kristal yap\u0131s\u0131, farkl\u0131 kimyasal bile\u015fimlerin yan\u0131 s\u0131ra elektriksel \u00f6zelliklere sahip \u00e7oklu tipler olu\u015fturur; suda \u00e7\u00f6z\u00fcnmezken alkalilerde veya demir i\u00e7eren ortamlarda \u00e7\u00f6z\u00fcn\u00fcr.<\/p>\n
SiC, yar\u0131 iletkenlik g\u00f6stermesini sa\u011flayan \u00e7ok daha geni\u015f bir bant aral\u0131\u011f\u0131 ile silikondan ayr\u0131l\u0131r. Bu nedenle, y\u00fcksek voltaj uygulamalar\u0131 i\u00e7in ideal bir malzeme se\u00e7imidir ve silikonun tolere edebilece\u011finden on kat daha y\u00fcksek voltajlara dayan\u0131r.<\/p>\n
Silisyum karb\u00fcr, standart silikonun 175 derece s\u0131n\u0131r\u0131ndan \u00f6nemli \u00f6l\u00e7\u00fcde daha y\u00fcksek olan 1.400 dereceye kadar s\u0131cakl\u0131klara dayanmas\u0131n\u0131 sa\u011flayan \u00fcst\u00fcn termal iletkenli\u011fe sahiptir. Bu nedenle silisyum karb\u00fcr, DC-DC d\u00f6n\u00fc\u015ft\u00fcr\u00fcc\u00fcler ve yerle\u015fik \u015farj cihazlar\u0131 gibi g\u00fc\u00e7 elektroni\u011fi cihazlar\u0131nda aktif so\u011futma sistemlerine olan ihtiyac\u0131 azalt\u0131r.<\/p>\n
Silisyum karb\u00fcr, reaksiyon-ba\u011fl\u0131 ve CVD y\u00f6ntemleri de dahil olmak \u00fczere \u00e7e\u015fitli s\u00fcre\u00e7lerle \u00fcretilebilir. Reaksiyona ba\u011fl\u0131 y\u00f6ntemler, toz haline getirilmi\u015f SiC'nin karbon tozu ve plastikle\u015ftirici ile kar\u0131\u015ft\u0131r\u0131lmas\u0131n\u0131 ve kar\u0131\u015f\u0131mda bulunan plastikle\u015ftiriciyi yakmadan \u00f6nce istenen \u015fekillerde \u015fekillendirilmesini i\u00e7erir.

Silisyum karb\u00fcr veya SiC, bilinen en sert maddelerden biridir. \u00d6ncelikle spor arabalar ve s\u00fcper arabalar i\u00e7in y\u00fcksek performansl\u0131 fren disklerinde bir otomotiv malzemesi olarak kullan\u0131l\u0131r; ancak yar\u0131 iletkenler ve g\u00fc\u00e7 elektroni\u011fi bile\u015fenleri de y\u00fcksek voltaj uygulamalar\u0131 i\u00e7in uygun hale getiren m\u00fckemmel fiziksel ve elektriksel \u00f6zellikleri nedeniyle bu malzemeyi kullan\u0131r.<\/p>\n
Arzu edilen oksit olmayan seramik \u00f6zelliklere sahip seramik malzemeler, sens\u00f6rler ve yar\u0131 iletken cihazlardan giyilebilir teknoloji ve t\u0131bbi implantlara kadar bir\u00e7ok end\u00fcstriyel uygulama i\u00e7in m\u00fckemmel bir se\u00e7imdir. \u00c7e\u015fitli miktarlarda al\u00fcminyum, bor veya karbon katk\u0131l\u0131 seramik, \u00e7e\u015fitli end\u00fcstriyel kullan\u0131mlar i\u00e7in belirli performans \u00f6zellikleri elde edebilir ve y\u00fcksek voltajl\u0131 kullan\u0131m i\u00e7in d\u00fc\u015f\u00fck voltajl\u0131 cihazlar halinde \u00fcretilebilir.<\/p>\n
SiC'nin atomik yap\u0131s\u0131 onu m\u00fckemmel bir iletken haline getirerek elektrikli ara\u00e7larda (EV'ler) transist\u00f6r olarak kullan\u0131m i\u00e7in ideal k\u0131lmaktad\u0131r. Bu \u00e7ipler, daha fazla verimlilik ve daha uzun pil \u00f6mr\u00fc i\u00e7in \u00e7al\u0131\u015fma s\u0131ras\u0131nda olu\u015fan \u0131s\u0131y\u0131 azaltman\u0131n yan\u0131 s\u0131ra daha y\u00fcksek \u00e7al\u0131\u015fma s\u0131cakl\u0131klar\u0131na dayanabilir ve b\u00f6ylece bir EV'nin tasar\u0131m\u0131na a\u011f\u0131rl\u0131k ve karma\u015f\u0131kl\u0131k katan aktif so\u011futma sistemlerini ortadan kald\u0131r\u0131r.<\/p>\n
