Ukubunjwa kweMichiza kunye ne-Crystal Framework
ICarborundum yikhompawundi eyenziweyo eyenziwe ngesilicon kunye nekhabhoni, iveliswa ngokwesiqhelo ngempendulo yobushushu obuphezulu besilica kunye nemithombo yekhabhoni efana necoke yeoli kwisifudumezi sombane.. Ithatha imilo kwiipolytypes ezininzi, ebandakanya i-alpha-SiC (ihexagonal) kunye ne-beta-SiC (cubic), ngamnye usebenzisa amakhaya ahlukeneyo ngokwasemzimbeni. Ngobunzima be-Mohs ngeenxa zonke 9.5, 2kunye nerubhi kunye ne-cubic boron nitride, I-SiC ibonisa ukuxhathisa okugqwesileyo kunye nokunyamezela ukothuka kwe-thermal. I-bandgap yayo enkulu iyenza ibe yimveliso ephambili kwizixhobo zombane ezinamandla aphezulu, apho iisemiconductor ezisemgangathweni zingaphumeleli.
Ubuchwephesha beMveliso kunye noLawulo loMda weNcam
Ukwenziwa komgubo we-carborundum kubandakanya ulawulo oluchanekileyo kwizibonelelo, ubushushu, kunye namaxabiso okupholisa ukuze kuphunyezwe ubungakanani obufunwayo beqhekeza kunye nemorphologies. Iindlela zokuvelisa eziqhelekileyo ziquka inkqubo ye-Acheson, evelisa iinkozo ezikrwada ezilungele ukusetyenziswa ngokurhabaxa, kunye nobuchule obuphambili obufana nokubekwa komphunga wekhemikhali (CVD) kunye ne-sol-gel processing, evumela i-ultra-fine okanye i-nanostructured powders eyenzelwe i-ceramics yokusebenza okuphezulu kunye ne-electronics. Uphuhliso lwangoku lugxile ekunciphiseni ukusetyenziswa kwamandla ngexesha lemveliso kunye nokuphucula ukuhambelana kwamaqhekeza ukuze kuhlangatyezwane nemigaqo engqongqo yeshishini..
Umsebenzi kwiAbrasive Applications: Ukusila, Ukusika, kunye nokugudiswa
Phakathi kolona setyenziso lwaziwayo lwe-carborundum powder ilele kwizicelo ezirhabaxa, apho ukuqina kwayo okuphezulu kunye nokugcinwa okubukhali kwecala kuyenza ibe yeyona nto ilungileyo yokusila, ukuqhushumba kwesanti, kunye neenkqubo zokupholisha. Isetyenziswa kakhulu kwiibrasives ezincamatheleyo ezifana namavili okusila, ii-abrasives ezigqunywe njengephepha lesanti, kunye neziqhushumbisi ezikhululekileyo zokuvasa nokucokisa. Xa kuthelekiswa neziqholo zemveli ezifana nobunzima bokukhanya kwe-aluminiyam oxide, I-carborundum isebenzisa ubuchule obumangalisayo ekunciphiseni izinga, ukumelana nobushushu, kunye nobomi besixhobo– ukuyenza ibaluleke ngakumbi kumsebenzi wesinyithi, ukulungiswa kwamatye, kunye nomatshini wezinto ezidibeneyo.
IiCeramics eziPhezulu kunye nezicelo eziLawulayo
Ngaphandle kwe-abrasives, i-carborundum powder idlala umsebenzi obalulekileyo ekwakhiweni kwezinto ezintsha ze-ceramic ezihamba phantsi kweengxaki ezinzima. Ngenxa ye-conductivity ephezulu ye-thermal kunye nokunciphisa ukuphuhliswa kwe-thermal, Ii-ceramics ezisekelwe kwi-SiC zisetyenziswe ngokucokisekileyo kwifenitshala ye-kiln, izinto eziko, kunye nezitshintshi zobushushu. Kwicandelo leemoto, I-silicon carbide isetyenziswa kwiidiski ze-brake kunye ne-clutch yezithuthi ezisebenza kakhulu ngenxa yomthamo wayo wokumelana nokukhuhlana okukhulu kunye namaqondo obushushu aphezulu.. Usetyenziso lwe-aerospace lukwaxhamla kwizakhiwo zayo ezinobunzima bokukhanya kunye ne-oxidation-resistant, ngokukodwa kwimilomo yerokhethi kunye neencakuba zeinjini yomoya.
I-Semiconductor kunye ne-Electronic Device Assimilation
Kule minyaka yangoku, I-carborundum powder iye yavela njengeyona nto ibalulekileyo kwimveliso ye-semiconductor, ngokukodwa kwi-electronics yamandla kunye ne-optoelectronics. I-silicon ye-carbide wafers evela kwi-powder ye-SiC ecocekileyo isetyenziswa ekwenzeni iidiode., iitransistor, kunye ne-thyristors esebenzayo ekusebenzeni kumbane omkhulu, rhoqo, kunye namaqondo obushushu kune-silicon-based equivalents. Ezi mpawu zenza iigajethi ezisekelwe kwi-SiC ziyimfuneko kwizithuthi zombane, iziguquli zemithombo ehlaziyekayo, kunye nesakhelo sonxibelelwano lwe-5G. Njengoko imfuno yombane kunye ne-high-frequency electronics isanda, ngokunjalo nokubalwa kokubaluleka kwe-carborundum kwikhonkco lonikezelo lwe-semiconductor yehlabathi.
