Elektrikli ara\u00e7lara (EV'ler) a\u011f\u0131rl\u0131k ve maliyet katan aktif so\u011futma sistemlerine olan ba\u011f\u0131ml\u0131l\u0131\u011f\u0131 azaltabilir.<\/p>\n
Silisyum karb\u00fcr, s\u0131radan silisyumdan on kat daha fazla \u00fcst\u00fcn voltaj direncine sahiptir, hatta bu konuda galyum nitr\u00fcr\u00fc bile geride b\u0131rak\u0131r.<\/p>\n
Silisyum karb\u00fcr (SiC) bir\u00e7ok kullan\u0131m alan\u0131 olan end\u00fcstriyel bir malzemedir. \u00dcst\u00fcn tribolojik \u00f6zellikleri nedeniyle, genellikle kumlama nozullar\u0131nda, contalarda, mekanik yataklarda ve mekanik s\u0131zd\u0131rmazl\u0131k uygulamalar\u0131nda bulunur. Refrakterler ve seramikler de sertlik katt\u0131\u011f\u0131 i\u00e7in SiC kullan\u0131r.<\/p>\n
Su, alkol ve asit \u00e7\u00f6zeltilerinin hepsi onu tamamen \u00e7\u00f6zer; \u00e7o\u011fu organik \u00e7\u00f6z\u00fcc\u00fc de diren\u00e7li kal\u0131r. Yar\u0131 iletken \u00f6zellikleri nedeniyle, elektriksel \u00f6zellikleri baz\u0131 ilgin\u00e7 \u00f6zellikler sunar - diren\u00e7, bile\u015fimler aras\u0131nda yedi b\u00fcy\u00fckl\u00fck s\u0131ras\u0131na kadar farkl\u0131l\u0131k g\u00f6sterebilir!<\/p>\n
Edward Acheson ilk kez 1891 y\u0131l\u0131nda sentetik SiC \u00fcretirken, Henri Moissan ilk kez 1905 y\u0131l\u0131nda Arizona'daki Canyon Diablo meteoritini ke\u015ffederken do\u011fal formunu tan\u0131mlam\u0131\u015ft\u0131r. G\u00fcn\u00fcm\u00fczde sat\u0131lan t\u00fcm ticari SiC sentetiktir, do\u011fal olarak olu\u015fabilen mozanit m\u00fccevherler i\u00e7in baz\u0131 istisnalar vard\u0131r.<\/p>\n
Silisyum karb\u00fcr veya SiC, \u00e7ok say\u0131da avantajl\u0131 fiziksel \u00f6zelli\u011fe sahip ola\u011fan\u00fcst\u00fc bir seramiktir. Bunlar aras\u0131nda y\u00fcksek mukavemet, d\u00fc\u015f\u00fck termal genle\u015fme oran\u0131 ve korozyona ve kimyasal reaksiyonlara kar\u015f\u0131 direnci yer al\u0131r - bu \u00f6zellikler onu a\u015f\u0131nd\u0131r\u0131c\u0131 malzeme ve refrakter bile\u015fen olarak kullan\u0131ma uygun hale getirmenin yan\u0131 s\u0131ra m\u00fckemmel elektrik iletkenli\u011fi de sa\u011flar.<\/p>\n
Mohs \u00f6l\u00e7e\u011finde 9 olan kriyojenik sertlik, refrakter porseleni ta\u015flama ta\u015flar\u0131 ve di\u011fer a\u015f\u0131nd\u0131r\u0131c\u0131 \u00fcr\u00fcnler i\u00e7in m\u00fckemmel bir malzeme haline getirmenin yan\u0131 s\u0131ra br\u00fcl\u00f6r nozullar\u0131 ve alev t\u00fcpleri gibi refrakter uygulamalarda da kullan\u0131l\u0131r.<\/p>\n
Kriyojenik grafit, politipler olarak bilinen \u00e7e\u015fitli \u00e7e\u015fitlerde bulunur ve do\u011frudan ba\u011flanm\u0131\u015f tetrahedral birimler aras\u0131ndaki ba\u011flarla ba\u011flanm\u0131\u015f d\u00f6rt karbon ve d\u00f6rt silikon atomu i\u00e7eren birincil koordinasyon tetrahedral d\u00fczenlemesine sahiptir. Bu birimler daha sonra farkl\u0131 yap\u0131lar olu\u015fturmak i\u00e7in birbirine ba\u011flanabilir veya istiflenebilir.<\/p>\n
Silisyum karb\u00fcr, y\u00fcksek voltaj uygulamalar\u0131 i\u00e7in geni\u015f bir bant aral\u0131\u011f\u0131na sahip, y\u00fcksek s\u0131cakl\u0131klara dayanabilen dayan\u0131kl\u0131 ancak k\u0131r\u0131lgan bir malzemedir.<\/p>\n
End\u00fcstriyel \u00f6l\u00e7ekte, silika tozu \u00fcretilir ve seramiklerde, refrakter malzemelerde ve yar\u0131 iletken elektroniklerde kullan\u0131l\u0131r. Do\u011fal olarak mozanit mineral olu\u015fumlar\u0131nda bulunsa da, g\u00fcn\u00fcm\u00fczde \u00e7o\u011fu sentetik olarak \u00fcretilmektedir.<\/p>\n
Kil ba\u011fl\u0131 silisyum karb\u00fcr refrakterler m\u00fckemmel korozyon direnci sunarak demir d\u0131\u015f\u0131 metal eritme uygulamalar\u0131 i\u00e7in f\u0131r\u0131n tu\u011flalar\u0131 olarak uygun hale getirir. Ayr\u0131ca, al\u00fcminyum elektroliz tanklar\u0131 i\u00e7in astar tu\u011flalar\u0131 veya bak\u0131r eritme f\u0131r\u0131nlar\u0131nda rektifikasyon f\u0131r\u0131n\u0131 tepsisi astarlar\u0131 veya \u00e7inko tozu f\u0131r\u0131n ark plakalar\u0131 gibi harika y\u00fcksek s\u0131cakl\u0131k dolayl\u0131 \u0131s\u0131tma malzemeleri yaparlar.<\/p>\n
Silisyum karb\u00fcr, mukavemeti nedeniyle a\u015f\u0131nd\u0131r\u0131c\u0131larda, refrakterlerde, a\u015f\u0131nmaya dayan\u0131kl\u0131 bile\u015fenlerde ve a\u015f\u0131nma esnekli\u011fi bile\u015fenlerinde yayg\u0131n olarak bulunan son derece sert, oksit olmayan seramik bir malzemedir. Ayr\u0131ca, silisyum karb\u00fcr, y\u00fcksek s\u0131cakl\u0131klarda veya voltajlarda \u00e7al\u0131\u015fan elektronik sistemlerde ayr\u0131lmaz bir malzeme olarak hizmet eder.<\/p>\n
Do\u011fada nadir bulunan ve yaln\u0131zca sentetik y\u00f6ntemlerle yapay olarak \u00fcretilen mozanit ilk olarak 1893 y\u0131l\u0131nda Arizona'n\u0131n Diablo Kanyonu'nda ke\u015ffedilmi\u015f ve daha sonra Edward Acheson'un 1891 y\u0131l\u0131nda yapay yollarla k\u00fc\u00e7\u00fck siyah SiC kristalleri olu\u015fturma patentiyle mozanit ad\u0131n\u0131 alm\u0131\u015ft\u0131r.<\/p>\n
Bu kalibredeki seramik malzeme \u00fcst\u00fcn \u00f6zellikler sunar. Silikon yar\u0131 iletkenlerden daha y\u00fcksek bir \u00e7al\u0131\u015fma s\u0131cakl\u0131\u011f\u0131 aral\u0131\u011f\u0131na sahiptir ve a\u015f\u0131r\u0131 \u0131s\u0131nmaya veya hasara yenik d\u00fc\u015fmeden daha y\u00fcksek voltajlar\u0131 kald\u0131rabilir.<\/p>\n
Silisyum karb\u00fcr, \u00e7ok say\u0131da uygulamada kullan\u0131lan \u00e7ok y\u00f6nl\u00fc bir refrakter seramiktir. Mohs sertlik \u00f6l\u00e7e\u011finde en sert malzemelerden biri olan silisyum karb\u00fcr, sertlik a\u00e7\u0131s\u0131ndan 9. s\u0131rada yer al\u0131r. Ayr\u0131ca, hem a\u015f\u0131nma ve korozyona hem de termal \u015foka kar\u015f\u0131 m\u00fckemmel diren\u00e7 g\u00f6sterirken, y\u00fcksek s\u0131cakl\u0131klara ve voltajlara hasar veya bozulma olmadan dayan\u0131r.<\/p>\n
\u00c7o\u011fu kristal yap\u0131da oldu\u011fu gibi, kristal yap\u0131s\u0131 da her biri kendi istifleme s\u0131ras\u0131na sahip \u00e7e\u015fitli formlarda - veya polip tiplerinde - gelir. Birincil koordinasyon tetrahedralar\u0131, k\u00f6\u015felerinden polar yap\u0131lara ba\u011flanm\u0131\u015f d\u00f6rt karbon ve d\u00f6rt silikon atomundan olu\u015fur.<\/p>\n
Ola\u011fan\u00fcst\u00fc tribolojik \u00f6zellikleri nedeniyle plastik, pompalar, mekanik salmastralar ve rulmanlar, kimya end\u00fcstrisi ekipmanlar\u0131 ve a\u015f\u0131nd\u0131r\u0131c\u0131 olarak m\u00fckemmel bir malzemedir.<\/p>\n
Silisyum karb\u00fcr d\u00fcnyan\u0131n en \u00e7ok y\u00f6nl\u00fc malzemelerinden biridir. Y\u00fcksek performansl\u0131 elektrikli ara\u00e7larda (EV'ler) ve batarya y\u00f6netim sistemlerinde \u00f6nemli bir rol oynar; burada y\u00fcksek voltaj \u00f6zellikleri, EV'lere maliyet, a\u011f\u0131rl\u0131k ve karma\u015f\u0131kl\u0131k katan aktif so\u011futma sistemlerini ortadan kald\u0131r\u0131r.<\/p>\n
Genellikle karborundum olarak bilinen sert bir seramik ve yar\u0131 iletken malzeme olan karborundum, mozanit minerallerinde do\u011fal olarak bulunabildi\u011fi gibi sentetik olarak da \u00fcretilebilmektedir. Silikon gibi geleneksel yar\u0131 iletkenlerin aksine karborundum, elektri\u011fin her zamankinden daha verimli bir \u015fekilde ta\u015f\u0131nmas\u0131n\u0131 sa\u011flayan geni\u015f bir bant aral\u0131\u011f\u0131na sahiptir. Dahas\u0131, kristal yap\u0131s\u0131na safs\u0131zl\u0131klar eklenerek iletkenli\u011fi de\u011fi\u015ftirilebilir.<\/p>\n
Silisyum karb\u00fcr (SiC), elektrik g\u00fcc\u00fcn\u00fc alternatif ak\u0131ma d\u00f6n\u00fc\u015ft\u00fcrmek i\u00e7in enerji tasarruflu bir malzemedir, bu da onu \u015febeke kayna\u011f\u0131ndan elektrik g\u00fcc\u00fcn\u00fcn d\u00f6n\u00fc\u015ft\u00fcr\u00fclmesi i\u00e7in uygun hale getirir. SiC'nin azot veya fosfor ile katk\u0131lanmas\u0131 n-tipi bir yar\u0131 iletken olu\u015ftururken, al\u00fcminyum, bor veya galyum ile katk\u0131lanmas\u0131 p-tipi yar\u0131 iletken \u00f6zelliklerine yol a\u00e7ar.<\/p>\n
Al\u00fcminyum m\u00fckemmel termal iletkenlik, y\u00fcksek s\u0131cakl\u0131k dayan\u0131m\u0131, d\u00fc\u015f\u00fck termal genle\u015fme ve kimyasal reaksiyon direnci sunar - bu nitelikler onu ideal refrakter malzeme yapar. Ayr\u0131ca, sert ve dayan\u0131kl\u0131 y\u00fczeyi onu bir\u00e7ok end\u00fcstriyel kullan\u0131m i\u00e7in uygun hale getirir ve m\u00fckemmel bir refrakter malzeme se\u00e7imi yapar.<\/p>\n
Do\u011fal SiC nadir mineral mozanit olarak bulunur; sentetik olarak seramik uygulamalar\u0131 i\u00e7in seramik veya refrakterler halinde birbirine ba\u011flanm\u0131\u015f k\u00fc\u00e7\u00fck taneler halinde \u00fcretilir veya karbonlu kondrit meteoritlerinde ve kimberlitlerde az miktarda bulunur.<\/p>","protected":false},"excerpt":{"rendered":"
