Umbhobho we-silicon carbide: "indlu yamandla" entsha kwindawo yoshishino

Kwintsimi yoshishino, iipayipi ziyinxalenye ebalulekileyo yokuthutha imidiya eyahlukeneyo, kwaye ukusebenza kwabo kuchaphazela ngokuthe ngqo ukusebenza kwemveliso kunye nokhuseleko. Ngenkqubela phambili eqhubekayo yezinto zesayensi,imibhobho ye-silicon carbideziye zavela kwaye ngokuthe ngcembe zavela kumashishini amaninzi kunye nothotho lweempawu ezibalaseleyo.
I-Silicon carbide, ngokwemiqathango yokubunjwa, i-compound eyakhiwe ngezinto ezimbini: i-silicon (Si) kunye ne-carbon (C). Ukusuka kumbono we-microscopic, ii-athomu zayo ziqhagamshelwe ngokuqinileyo ngeebhondi ezidibeneyo, zenza i-lattice ezinzileyo kunye ne-odolo. Olu lwakhiwo lukhethekileyo lunika i-silicon carbide imibhobho enoluhlu lweempawu ezibalaseleyo.
Okokuqala, imibhobho ye-silicon carbide inokumelana okugqwesileyo kokunxiba. Kwamanye amajelo osasazo afuna ukuthuthwa kwamasuntswana aqinileyo, afana nokuthuthwa komgubo wamalahle kwimveliso yombane oshushu kunye nokuthuthwa kwe-ore slurry kwishishini lezemigodi, imibhobho eqhelekileyo iya kufumana ngokukhawuleza ukuguga, ukubhitya, kunye nokugqobhoza phantsi kokhukuliseko oluqhubekayo lwamasuntswana, okukhokelela ekutshintshweni kwemibhobho rhoqo, enganyusi nje iindleko kuphela kodwa ikwachaphazela imveliso. Imibhobho ye-silicon ye-carbide, ngenxa yeempawu zobunzima obuphezulu, inokuxhathisa ngokufanelekileyo ukukhukuliseka kwe-particle kunye nokugqoka, ukwandisa kakhulu ubomi benkonzo yemibhobho kunye nokunciphisa ukuphindaphinda kokugcinwa kunye nokutshintshwa.
Okwesibini, ukumelana nobushushu obuphezulu bemibhobho ye-silicon carbide ibalasele kakhulu. Kwiindawo eziphakamileyo zokushisa, amandla emibhobho yentsimbi eqhelekileyo aya kuncipha kakhulu, kunye nokuguqulwa, ukuthambisa, kunye nezinye iingxaki. Umzekelo, kwimizi-mveliso enobushushu obuphezulu obunje ngokwenziwa kwesinyithi kunye neglasi, amaqondo obushushu adla ngokufikelela kumakhulu okanye namawaka edigri ngokukaCelsius. Ngaphantsi kweemeko ezinjalo zokushisa eziphezulu, iipayipi ze-silicon carbide zisenako ukugcina iipropati ezizinzileyo zomzimba kunye neekhemikhali, ziqinisekisa ukusebenza okuqhelekileyo kwemibhobho kunye nokugcina ukuveliswa kwemveliso.

Okokugqibela, imibhobho ye-silicon ye-carbide nayo inokumelana nokugqwala okuhle. Kwinkqubo yokuvelisa imichiza, ihlala ibandakanya ukuthuthwa kwemithombo yeendaba eyonakalisayo efana ne-acids eyomeleleyo kunye nealkali. Imibhobho eqhelekileyo ithanda ukudleka, nto leyo ekhokelela ekuvuzeni okuphakathi, okungachithi nje kuphela izibonelelo kodwa kunokubangela iingozi zokhuseleko. Imibhobho ye-silicon carbide, kunye nokuzinza kweekhemikhali, inokumelana nokukhukuliseka kweekhemikhali ezahlukeneyo, ukuqinisekisa ukhuseleko kunye nokuzinza kwemveliso.
Imibhobho ye-silicon ye-carbide, eneenzuzo ezininzi ezifana nokunganyangeki, ukumelana nobushushu obuphezulu, kunye nokumelana nokugqwala, ngokuthe ngcembe iba yintandokazi entsha kwintsimi yombhobho wezoshishino, inika iziqinisekiso ezinamandla zokuvelisa ngokufanelekileyo kunye nokuzinza kumashishini amaninzi. Ngophuhliso oluqhubekayo lwetekhnoloji kunye nokuphucula ngakumbi iindleko, sikholelwa ukuba iipayipi ze-silicon carbide ziya kuba noluhlu olubanzi lwezicelo kunye nethemba lophuhliso olubanzi kwixesha elizayo.
