Ehlabathini lokuvelisa ngokuchanekileyo, kukho izinto ezixhasa ngokuthula ukuphuhliswa kwamashishini amaninzi aphezulu - kunzima kunentsimbi, ubushushu obuphezulu kune-graphite, kodwa ihlala igcina umzimba obunzima. Yi leipleyiti ye-silicon carbide ceramic, "imetamaterial" eyimfuneko kwishishini lanamhlanje.
1, Izipho zendalo kunye nokukhanya kobulumko bomntu
I-Silicon carbide (i-SiC) ayiyona imveliso yengozi kwibhubhoratri. Kwangoko ngo-1893, izazinzulu zafumanisa le minerali yenzeka ngokwemvelo. Kule mihla, ngokusebenzisa itekhnoloji ye-high-temperature synthesis yokudibanisa kwakhona isanti ye-silicon kunye nemithombo yekhabhoni kumaqondo aphezulu okushisa, i-industrial grade silicon carbide ceramics kunye nokusebenza okungcono kuyadalwa. Esi sixhobo sidibanisa ngokugqibeleleyo ukuzinza kweekeramics kunye neempawu ze-semiconductors, ukwenza i-gene yempahla ekhethekileyo.
2, Susa ikhowudi ezintlanu eziluncedo
1. Umgcini wobushushu obuphezulu
Phantsi kweemeko ezigqithisileyo ze-1350 ℃, iintsimbi eziqhelekileyo sele zithambe kwaye zonakele, ngelixa iipleyiti ze-silicon carbide ceramic zisenokugcina imfezeko yesakhiwo. Oku kuxhathisa ubushushu obuphezulu kukwenza kube lolona khetho lufanelekileyo kumasimi anje ngesixhobo sokunyibilika kunye neenjini ze-aerospace.
2. Ikhaka elikhuselayo elomeleleyo
Ukuqina, okwesibini kuphela kwidayimane, ivumela iipleyiti ze-silicon carbide ukuba zixhathise ngokulula ukhukuliseko kunye nefuthe lesuntswana lentsimbi etyhidiweyo. Kumgca wokuphosa we-aluminium, ixesha lokuphila kwayo likwandiswa ngamaxesha angaphezu kwama-5 xa kuthelekiswa nezixhobo zendabuko eziphikisayo.
3. Unobuchule ekuqhubeni ubushushu
Ngokungafaniyo neempawu ze-"insulation" zeekeramics eziqhelekileyo, i-silicon carbide ceramics ine-conductivity egqwesileyo ye-thermal. Le nto "ephefumulayo" inokudlulisa ngokukhawuleza ukushisa ngelixa igcina ukuzinza kwayo, okwenza ukuba isebenze kakhulu kwintsimi yokutshatyalaliswa kokushisa kwe-semiconductor.
4. Uvulindlela Olula
Ngamandla afanayo, ubunzima bayo buyinto enye yesithathu kuphela yentsimbi. Olu phawu "lokuphakamisa izinto ezinzima kancinci" kuzisa izisombululo zokunciphisa ubunzima kwimimandla efana nezixhobo zamandla amatsha kunye nohambo lukaloliwe.
5. UMkhuseli weMichiza
Ujongene nemithombo yeendaba eyonakalisa kakhulu, iiseramics zesilicon carbide zibonisa uzinzo olumangalisayo. Kwisixhobo sokwenza imichiza, kufana nomgadi ongazange avuthe, eqinisekisa ukhuseleko lwemveliso.
3, Amathuba angenasiphelo okutshintsha ikamva
Ukusuka kwi-substrate ethwele umthwalo weeseli ze-photovoltaic ukuya kumacandelo angagugiyo oomatshini bokuchaneka, ukusuka kwisiseko sokushisa ubushushu beetships ze-semiconductor ukuya kwimodyuli yokucoca yezixhobo zokukhusela okusingqongileyo, iipleyiti ze-silicon carbide ceramic zichaza kwakhona imida yokusebenza kwezinto zoshishino. Kwiinkalo ezicwangcisiweyo ezifana namandla amatsha, ulwazi lwe-elektroniki, kunye nezixhobo eziphezulu, izixhobo ze-silicon carbide ceramic ziqhuba ngokuzolileyo ukuphuculwa kwemizi-mveliso.
Njengomqambi wetekhnoloji obandakanyeka ngokunzulu kwinkalo yeekeramics ezikhethekileyo, sihlala sizibophelele ekutyhaleni ukusebenza kwezinto ze-silicon carbide ngokugqithiseleyo. Ngokuqhubeka nokuphucula iinkqubo ze-sintering kunye neendlela zokwenza unyango lwangaphezulu, ibhodi nganye ye-ceramic iba ngumsebenzi wobugcisa obunokumelana novavanyo lwexesha. Ikamva lilapha, masingqinelane kunye umtsalane okhethekileyo we-silicon carbide ceramics eqhakaza kwiindawo ezininzi.
UShandong Zhongpeng uhlala ebambelele kwingqikelelo "yokwenziwa kwezinto ezintsha kuqhuba inkqubela phambili yeshishini", kwaye ujonge phambili ekusebenzisaneni namaqabane ehlabathi ukuphonononga amathuba angenasiphelo esicelo se-silicon carbide ceramics.
