Mukushandiswa kwekupisa kwakanyanya, kusarudza zvinhu zvakakosha. Pakati pazvo, zvinhu zvesilicon carbide zvinosanganiswa ne reaction-sintered zvakava sarudzo yakakurumbira nekuda kwekushanda kwayo kwakanaka. Silicon carbide inosanganiswa ne reaction-sintered ipurasitiki inoumbwa ne reaction sintering yecarbon nesilicon powder pakupisa kwakanyanya.
Chekutanga, reaction-sintered silicon carbide ine kugadzikana kwakanyanya pakupisa kwakanyanya. Inokwanisa kuchengetedza simba rayo remakanika uye kugadzikana kwemakemikari pakupisa kwakanyanya kusvika ku2,000 degrees Celsius. Izvi zvinoita kuti ive yakakodzera kushandiswa pakupisa kwakanyanya, senge muindasitiri yekuchenesa mafuta, simbi uye ceramic.
Chechipiri, reaction-sintered silicon carbide ine simba guru rekuramba kupfekwa. Chinhu ichi chine simba guru rekuramba kupfekwa uye chinogona kuramba chakasimba kwenguva yakareba munzvimbo dzine kukweshana kwakanyanya uye kupfekwa. Nokudaro, chinoshandiswa zvakanyanya muminda yekukuya, kucheka uye maturusi ekukwesha.
Pamusoro pezvo, reaction-sintered silicon carbide inewo thermal conductivity yakanaka uye chemical inertia. Inogona kupisa nekukurumidza uye inodzivirira ngura munzvimbo dzine ngura dzakadai seacid nealkali. Izvi zvinoita kuti ishandiswe zvakanyanya muindasitiri yemakemikari uye mukutonga kwekupisa.
Zvinofanira kucherechedzwa kuti maitiro ekugadzirira reaction-sintered silicon carbide akaoma, anoda tembiricha yepamusoro uye mamiriro chaiwo e reaction. Zvisinei, nekufambira mberi kuri kuitwa tekinoroji, maitiro ekugadzira akavandudzwa zvishoma nezvishoma, zvichiita kuti mutengo wechinhu chacho uderedzwe zvishoma nezvishoma, uye zvichikurudzira kushandiswa kwacho munzvimbo dzakasiyana-siyana.
Muchidimbu, sezvinhu zvinopisa zvakanyanya, reaction-sintered silicon carbide isarudzo yakanaka kune akawanda mashandisirwo ekupisa kwakanyanya nekuda kwekugadzikana kwayo kwakanyanya pakupisa, kuramba kupfeka, thermal conductivity uye chemical inertia. Sezvo tekinoroji iri kuramba ichikura, tinogona kutarisira kuti reaction-sintered silicon carbide ishandiswe muminda yakawanda uye kuwedzera kushanda kwayo.
