Izitshintshi zobushushu zeSilicon (SiC) zisetyenziswa kakhulu kumacandelo ekhemikhali, amandla, kunye nokhuselo lokusingqongileyo ngenxa yokumelana nobushushu obuphezulu-, ukumelana nokudleka, kunye ne-thermal conductivity ephezulu. Nangona kunjalo, ukusebenza kwabo kuxhomekeke kakhulu ekukhethweni kwezinto eziphathekayo, kwaye ukudibanisa kwezinto ezifanelekileyo kuchaphazela ngokuthe ngqo ubomi benkonzo yesixhobo kunye nokusebenza kakuhle.
Okokuqala, i-silicon carbide ceramic yeyona nto ikhethwayo kwizinto eziphambili zokutshintsha ubushushu. -ubunyulu be-silicon carbide (umzekelo, ngaphezulu kwe-98%) inomxholo wokungcola ophantsi kakhulu, iphucula kakhulu ukuxhathisa ukutshatyalaliswa kwe-thermal kunye nozinzo lwekhemikhali, iyenza ifaneleke ngokukodwa kwiindawo ezinemithombo yeendaba ezonakalisayo ezifana neeasidi ezinamandla kunye neziseko. Ngaphezu koko, i-conductivity yayo ephezulu ye-thermal (malunga ne-120-150 W / m·K) iqinisekisa ukuhanjiswa kobushushu ngokufanelekileyo kunye nokunciphisa ukulahlekelwa kwamandla.
Okwesibini, ukukhethwa kwezinto zokutywina kubaluleke ngokufanayo. Amatywina esinyithi esintu athanda ukusilela kumaqondo obushushu aphezulu, ngelixa igraphite okanye isilicon carbide -based composites (ezifana ne reaction{2}}ibhondi yesilicon carbide kunye ne graphite composite) zibonelela ngokutywinwa kokusebenza okuthembekileyo ngelixa ukwala uhlaselo lwekhemikhali. Kwiimeko zokusebenza ezigqithisileyo, zonke{4}}izakhiwo ze-silicon carbide ezidityanisiweyo zinokuphelisa umngcipheko wokusilela kwetywina, kodwa ngexabiso eliphezulu.
Ngaphaya koko, izinto zokudibanisa isinyithi (ezinje ngeeflange kunye nemibhobho) ziqhele ukwakhiwa ukusuka phezulu{0}}kubushushu{1}}i-alloys ezixhathisayo (ezifana ne-Inconel 600 okanye i-Hastelloy) ukuze zihambelane{3}}neempawu zobushushu eziphezulu zesilicon carbide kwaye zithintele ukubola kwe-electrochemical. Unyango lwakumphezulu (olufana neengubo okanye iplating) lunokwandisa ngakumbi ukunxiba kunye nokumelana ne-oxidation.
Isishwankathelo, ukukhethwa kwezinto eziphathekayo kwi-silicon carbide heat exchangers kufuna ukuqwalaselwa ngokubanzi kweempawu zeendaba, ubushushu kunye neemeko zoxinzelelo, kunye nokusebenza kakuhle kwezoqoqosho. Ngokwenza ulungelelwaniso lomzimba we-silicon carbide ceramic, izinto zokutywina, kunye nezixhobo zentsimbi ezincedisayo, ukuthembeka kwezixhobo kunye nobomi benkonzo bunokwandiswa ukuze kuhlangatyezwane neemfuno zezicelo zemizi-mveliso.
