Silicon carbide yog ib yam khoom siv zoo nkauj uas muaj ntau yam ntxwv tshwj xeeb. Silicon carbide muaj ob hom atoms: silicon thiab carbon. Cov atoms ntawd tau teeb tsa ua ib txoj hauv kev tshwj xeeb uas ua rau nws muaj peev xwm ua tau tej yam tshwj xeeb, uas nws tau sau tseg rau ntau xyoo lawm.
Rau ib qho, Semixlab silicon carbide hmoov muaj zog thiab tawv heev. Qhov no yog vim nws siv tau los ua cov cuab yeej txiav thiab sib tsoo. Nws kuj yog ib yam khoom uas muaj qhov kub siab, uas tuaj yeem tiv taus qhov kub siab heev yam tsis yaj. Qhov ntawd ua rau nws zoo rau cov khoom xws li lub tsheb nres thiab cov khoom siv cua sov. Silicon carbide kuj tseem siv roj av thiab tuaj yeem ua tus coj hluav taws xob, ua rau nws yog ib qho khoom siv yooj yim hauv cov khoom siv hluav taws xob.
Ob yam khoom siv raw siv los ua silicon carbide: ib hom carbon hauv daim ntawv ntawm graphite thiab silica lossis quartz qhov chaw. Ib qho sib tov uas muaj silicon carbide hmoov thiab silicon xuab zeb raug muab tso rau hauv lub cub tawg tshwj xeeb hauv kev ua cov silicon carbide crystals. Cov crystals no tom qab ntawd raug tsoo thiab sieve rau ntau qhov ntau thiab tsawg rau ntau yam kev siv. Qhov no yog ib qho txheej txheem qeeb thiab siv zog ntau, tab sis cov khoom kawg tsim nyog nws.
Vim nws cov khoom tshwj xeeb, Semixlab cov silicon carbides siv rau hauv ntau yam lag luam. Hauv kev lag luam tsheb nws siv rau cov ntaub nres, cov phaj clutch thiab cov khoom siv cav. Hauv kev lag luam aerospace, nws siv rau cov rocket nozzles thiab cov ntaub thaiv cua sov. Hauv kev lag luam hluav taws xob, qhov no yog qhov teeb meem nrog diodes thiab transistors. Cov kev xaiv yeej tsis muaj qhov kawg.
Qee qhov zoo kawg nkaus hauv silicon carbide yog nws hla qhov txwv rau cov ntawv thov uas cuam tshuam nrog cov khoom siv hluav taws xob yav tom ntej. Zoo heev rau cov khoom siv hluav taws xob, vim nws tuaj yeem tiv taus qhov kub thiab txias siab thiab cov hluav taws xob siab, txhua yam txhawb nqa lub tswv yim tias cov khoom siv yuav me dua, sib dua, thiab ua haujlwm zoo dua yog tias ua los ntawm silicon carbide. Rau tag nrho cov thev naus laus zis siab heev, tshwj xeeb tshaj yog rau cov khoom siv hluav taws xob me me, ua haujlwm hauv qhov kub thiab txias, hluav taws xob, thiab lub zog uas tsim los ntawm cov kab ke tam sim no thiab cov tshuab hluav taws xob tshiab, silicon carbide yeej sawv tawm ntau dua li lwm yam.
Semixlab silicon carbide wafers kuj muaj nyob rau hauv kwv yees li 250 daim ntawv crystalline, ua rau cov tshuaj sib xyaw ua ke nyuaj rau synthesize. Ob hom tseem ceeb yog alpha silicon carbide thiab beta silicon carbide. alpha-silicon-carbide ruaj khov heev ntawm qhov kub siab, thaum beta-silicon-carbide ruaj khov rau qhov kub qis. Txhua hom muaj nws lub luag haujlwm hauv ntau qhov chaw.
