Ukuqonda iimpawu zayo ngundoqo ekuphunyezweni okuyimpumelelo kumashishini ahlukeneyo.

Ukuqonda iPowder ye-Silicon Carbide ecocekileyo

Ukucoceka okuphezulu kwe-silicon carbide powder, edla ngokubizwa ngokuba yi-SiC powder, ifom ye-crystalline ye-silicon carbide kunye nokungcola okuncinci. Oku kucoceka okuphezulu kubaluleke kakhulu ekusebenzeni kwayo kwizicelo ezifunayo. Inqanaba lokucoceka lidla ngokuchazwa njengepesenti yomxholo we-SiC, kunye neepesenti eziphezulu ezibonisa ukungcola okuncinci. Iipropati ze powder, ezifana nokusabalalisa ubungakanani besuntswana, i-morphology, kunye nommandla ongaphezulu, ziyahluka kakhulu kuxhomekeke kwindlela yokuvelisa. Ezi zakhiwo zinempembelelo ngokuthe ngqo kwizicelo zayo zokugqibela.

Iindlela zokuvelisa zePowder ye-Silicon Carbide ecocekileyo ePhezulu

Zininzi iindlela ezisetyenziselwa ukuveliswa kwe ukucoceka okuphezulu kwe-silicon carbide powder. Ezona zixhaphakileyo ziquka:

Inkqubo yeAcheson

Inkqubo ye-Acheson yindlela yakudala ebandakanya ukusabela kobushushu obuphezulu be-silica (SiO₂) kunye nekhabhoni (C) kwiziko lombane. Le nkqubo ivelisa iikristale zeSiC ezinobungakanani obahlukeneyo kunye neemilo. Ngelixa ingabizi kakhulu, ivelisa umgubo ococekileyo ngokuthelekisa nezinye iindlela.

Ukubekwa kweMichiza yoMphunga (CVD)

I-CVD yindlela esetyenziswa kakhulu ekuveliseni ukucoceka okuphezulu kwe-silicon carbide powder kunye nobungakanani bamasuntswana alawulwayo kunye nemorphology. Izandulela zegesi, njenge-silane (SiH₄) kunye nemethane (CH₄), sabelane kumaqondo okushisa aphezulu ukwenza amaqhekeza e-SiC. Le ndlela ivumela ulawulo oluchanekileyo kwiimpawu zomgubo, okwenza kube yinto efanelekileyo kwizicelo ezikhethekileyo. I-CVD ikwakhokelela ekungcoleni okuncinci kunenkqubo ye-Acheson.

Ezinye iindlela

Ezinye iindlela, ezifana ne-sol-gel synthesis kunye nokunciphisa i-carbothermal, zikwasetyenziselwa ukudibanisa i-SiC ephezulu. Ezi ndlela zibonelela ngeenzuzo ezizodwa ngokuxhomekeke kwiimfuno ezithile zobungakanani besuntswana, imilo, kunye nobunyulu.

Ukusetyenziswa kwePowder yeCarbide yeSilicon ecocekileyo

Iimpawu ezikhethekileyo ze ukucoceka okuphezulu kwe-silicon carbide powder yenze ilungele uthotho lwezicelo, kuquka:

Ishishini leSemiconductor

Kwishishini le-semiconductor, i-SiC isetyenziselwa ukudala i-substrates yamandla aphezulu kunye nezixhobo ze-elektroniki ze-high-frequency. I-conductivity ephezulu ye-thermal kunye ne-bandgap ebanzi ye-SiC yenza ukuba ulwakhiwo lwe-electronics enamandla ngakumbi kunye nokuthembeka.

Iibrasives

Ngenxa yobunzima bayo kunye nokuzinza okuphezulu kwe-thermal, ukucoceka okuphezulu kwe-silicon carbide powder ifumana ukusetyenziswa okubanzi njenge-abrasive kwizixhobo zokusika, amavili okugaya, kunye neekhompawundi zokupholisha. Ubuchule bayo bokusika obuphezulu xa kuthelekiswa namanye ama-abrasives kwenza kube yinto ekhethiweyo kwiinkqubo ezahlukeneyo zoshishino.

IiRefractories

I-SiC's high melting point kunye ne-inertness yekhemikhali inegalelo ekusetyenzisweni kwayo kwii-refractories, izinto ezinokumelana nokushisa okuphezulu kakhulu. Oku kubaluleke kakhulu kwizicelo ezifana neziko lesinyithi kunye neereactor zobushushu obuphezulu.

IiCeramics kunye neComposites

Ukucoceka okuphezulu kwe-silicon carbide powder licandelo elixabisekileyo kwiiseramics eziphambili kunye nee-composites, eziboleka amandla aphezulu, ukuqina kunye nokumelana nokunxiba kwiimveliso zokugqibela. Oku kunegalelo kwizicelo ezahlukeneyo ezifana nokufakwa kwezixhobo zesikrweqe kunye namacandelo oshishino.

Ukukhetha iPowder yeCarbide yeSilicon eLungileyo ephezulu

Ukhetho olufanelekileyo ukucoceka okuphezulu kwe-silicon carbide powder ixhomekeke kwiimfuno ezithile zesicelo. Imiba ephambili ekufuneka iqwalaselwe ibandakanya:
