（2）Ukungakhuseleki kwiKhemikhali: Kumelana nokugqwala okuvela kwii-asidi (umz. i-sulfuric, i-hydrochloric), ii-alkalis, kunye neegesi ezisabelayo ezifana ne-chlorine okanye i-sulfur oxides.

Ukumelana nokurhawuzelelwa: Khusela kwiingceba ezikhukulisayo kwiibhedi ezimanzi, kwiigesi zamalahle, okanye kwimisebenzi yokwemba.

2. Ukuchaneka kunye nozinzo kwiimilinganiselo ezibalulekileyo

Kwiinkqubo zoshishino ezinobungozi obukhulu, ukuchaneka kubaluleke kakhulu. Iityhubhu zeSiC ziphucula ukuthembeka ngokwenza oku kulandelayo:

（1）Ukunciphisa Ukuphazamiseka Kwesignali: Iimpawu ezingahambisi umbane zithintela ukuphazamiseka kwe-electromagnetic kwiisensa ze-elektroniki.

（2）Uzinzo lweThermal: Ukuguquguquka kobushushu obuphantse bube zero kuqinisekisa ukulungelelaniswa okulinganayo kunye nokuchaneka komlinganiselo phantsi kotshintsho olukhawulezayo lobushushu.

（3）Ukunyaniseka Okungangenisi Gas: Ulwakhiwo olungenakungenwa luthintela ukungena kwegesi, olubalulekileyo kwiinkqubo zevacuum okanye i-atmospheres ezilawulwayo.

3. Ukuvumela iiTekhnoloji zeSizukulwana Esilandelayo ukuba iityhubhu zokukhusela zeSiC zivule izinto ezintsha kwiindawo ezisakhasayo:

（1）Uqoqosho lweHydrogen: Zisebenza njengeeshelufu ezihlala ixesha elide zeenzwa kwimveliso yehydrogen, indawo yokugcina, kunye neeseli zepetroli, ezimelana nokuqhekeka kunye nokuvezwa kweH₂ enoxinzelelo oluphezulu.

（2）Ukwenziwa kweeSemiconductor: Khusela ii-optical kunye ne-thermal sensors kwi-CVD (Chemical Vapor Deposition) reactors kwi-precursors ebolayo njenge-silane okanye i-ammonia.

（3）Ukuhlola iSithuba: Izixhobo zokukhusela kwiinjini zerokethi kunye neeprobe zeplanethi ezivela kwi-gradients ezishushu kakhulu kunye nemitha ye-cosmic.

4. Ukonga iindleko ngobude bexesha elide

Nangona iityhubhu zeSiC zineendleko eziphezulu kwangaphambili, iingenelo zazo zomjikelo wobomi zichaza ixabiso elitsha:

（1）Ixesha Lokungasebenzi Elincitshisiweyo: Iindlela zokuphelisa isinyithi okanye i-quartz nge-4–6x kwiindawo ezirhabaxa okanye ezine-asidi, nto leyo enciphisa ukugcinwa okungacwangciswanga.

（2）Iimfuneko zokuGcoba ezingadingi kufakwa: Ngokungafaniyo neentsimbi ezifuna ukugqunywa, iipropati zeSiC azinazo iindleko zokunyanga umphezulu eziphindaphindayo.

（3）Ukusetyenziswa kwakhona: Ukusinda kwimijikelo emininzi yenkqubo kwizicelo ezifana nokuphoswa kwesinyithi okanye ukwenziwa kweglasi ngaphandle kokuwohloka.

5. Ukwenziwa ngokwezifiso kwiimfuno ezizodwa

Iityhubhu zokukhusela zeSiC zilungelelanisa imingeni ethile ngobunjineli obulungiselelwe wena:

（1）Uyilo lweHybrid: Luxube neentsimbi okanye iiseramikhi ukuze kuhlanganiswe izinto ezininzi (umz. izihlanganisi ezinemisonto, iiflange).

（2）Utshintsho Lomphezulu: Ingaphakathi elikhazimlisiweyo lokusetyenziswa kwe-optical okanye ingaphandle elinobume obuthambileyo ukuphucula ukusasazwa kobushushu.

（3）Ukuguquguquka kobukhulu: Yenziwe ngeemilimitha (ii-reactors zelebhu) ukuya kwiimitha (ii-kilns zemizi-mveliso).

6. Ulungelelwaniso loZinzo

Iityhubhu zeSiC zixhasa iindlela zoshishino ezinobuhlobo nokusingqongileyo:

（1）Ukonga Amandla: Ukusebenza kakuhle kobushushu kunciphisa ukusetyenziswa kwepetroli yesithando ukuya kuthi ga kwi-20% xa kuthelekiswa nezikhuselo zesinyithi.

（2）Ukuncitshiswa kweNkunkuma: Ixesha elide lenkonzo linciphisa inkunkuma yezinto ezisetyenzisiweyo ngenxa yokutshintshwa rhoqo.

（3）Ukunciphisa ityhefu: Kuphelisa isidingo sokufaka izinto ezinobungozi (umz., ii-alloys ezisekelwe kwi-nickel) kwiindawo ezinobungozi.

I-Shandong Zhongpeng Special Ceramics Co., Ltd yenye yezona zisombululo zinkulu zezinto ezintsha ze-silicon carbide ceramic eTshayina. I-SiC technical ceramic: Ubunzima bukaMoh buyi-9 (Ubunzima bukaMoh obuyi-13), bunokumelana okuhle nokukhukuliseka kunye nokugqwala, ukukrala okugqwesileyo - ukumelana nokubola kunye nokuchasana ne-oxidation. Ubomi benkonzo yemveliso yeSiC bubude obuphindwe ka-4 ukuya ku-5 kune-92% ye-alumina material. I-MOR ye-RBSiC iphindwe ka-5 ukuya ku-7 kune-SNBSC, ingasetyenziselwa iimilo ezinzima ngakumbi. Inkqubo yokucaphula iyakhawuleza, ukuhanjiswa kunjengoko kuthembisiwe kwaye umgangatho awulingani. Sihlala siqhubeka nokuchasa iinjongo zethu kwaye sibuyisela iintliziyo zethu kuluntu.
