Kupera kwechinhu inyaya isingadzivisike mukugadzirwa kwemaindasitiri uye muhupenyu hwezuva nezuva. Kubva pakupera kwechinhu panguva yekushanda kwemakanika kusvika pakudonha kwemvura uye kudonha kwevhu panzvimbo dzekuvaka, kupera kwechinhu hakungoderedzi hupenyu hwebasa remidziyo chete, asi kunogonawo kuwedzera mari yekugadzirisa uye kukanganisa kushanda zvakanaka kwekugadzira. Pakati pezvinhu zvakawanda zvine chekuita nekupera kwechinhu, silicon carbide yave "mutambi we "hardcore" anodiwa nekuda kwekusapera kwayo kwakanaka, ichichengetedza chinyararire kushanda kwakagadzikana kweminda yakasiyana-siyana.
Chikonzero neikabhidhi yesiliconinogona kuva "mambo anodzivirira kupera" iri muchimiro chayo chakasiyana chekristaro. Imusanganiswa unoumbwa nezvinhu zviviri, silicon nekabhoni, zvakabatana zvakasimba ne covalent bonds. Simba rakasimba rekubatanidza kwemakemikari aya rinopa makristaro esilicon carbide kuomarara kwakanyanya - kuri kwechipiri kune diamond ne cubic boron nitride, kupfuura simbi dzakajairika nezvinhu zvakawanda zveceramic. Chimiro chekristaro chakaoma chakaita se "chinodzivirira chechisikigo", icho chinonetsa kukuvadza chimiro chemukati chesilicon carbide kana zvinhu zvekunze zvikaedza kukwesha kana kukwenya pamusoro, zvichibudirira kudzivirira kupera.
Pamusoro pekuoma kwayo, kugadzikana kwemakemikari kwesilicon carbide kunowedzerawo kuramba kwayo kupfeka. Haiwanzoitiki nemakemikari munzvimbo dzakaoma dzakadai sekupisa kwakanyanya uye acidity, uye haizokonzere kukuvara kwechimiro chepamusoro nekuda kwe oxidation kana ngura, nokudaro ichiramba yakasimba kuramba kupfeka. Ingave iri zvinhu zvinoramba zviri mumaovheni ane kupisa kwakanyanya kana ma lining plates anodzivirira kupera mumichina yekuchera, silicon carbide inogona kugara munzvimbo dzakaoma uye kuderedza kurasikirwa kunokonzerwa nekusakara.
Vanhu vazhinji vangave vasingazive nezve silicon carbide, asi yatove yakapinda muhupenyu hwedu hwese. Mubasa rekuvaka, pasi risingaparare rine silicon carbide yakawedzerwa rinogona kutsungirira kupwanywa kwemotokari kakawanda uye kufamba kwevashandi, zvichichengetedza ivhu rakatsetseka uye rakati sandara kwenguva yakareba; Mukugadzira michina, maturusi ekucheka nemavhiri ekukuya akagadzirwa nesilicon carbide zvinogona kucheka nekupukuta zviri nyore zvinhu zvesimbi yakaoma zvisina kusakara zvakanyanya; Kunyangwe mumunda wesimba idzva, mabheringi e ceramic e silicon carbide, ane hunhu hwawo husingaparare, anobatsira michina kuti ibudirire zvakanyanya uye igare kwenguva refu.
Sechinhu chakanaka kwazvo chisingapfeki, silicon carbide haingoratidzi runako rwesainzi yezvinhu chete, asiwo inoita basa rakakosha mukusimudzira kuvandudzwa kwemaindasitiri nekuderedza kushandiswa kwesimba. Nekufambira mberi kwetekinoroji, mamiriro ekushandiswa kwesilicon carbide achiri kuwedzera. Mune ramangwana, "mambo uyu asingapfeki" achaunza vimbiso inogara kwenguva refu uye yakavimbika kuminda yakawanda, achiratidza simba re "kutsungirira" nesimba.
