Silicon carbide (SiC) icovalent compound yakaumbwa nekabhoni nesilicon uye inozivikanwa nehunhu hwayo hwakanakisa, hunosanganisira kukwirira kupfeka kuramba, kupisa kwekuvhunduka, kuramba kwakasimba kwecorrosion uye yakakwirira kupisa kwekushisa. Izvi zvivakwa zvinoita kuti silicon carbide ive chinhu chakanakira kushandiswa kwakasiyana-siyana mumaindasitiri akawanda, anosanganisira aerospace, kugadzira muchina, petrochemicals, kunyungudutsa simbi uye zvemagetsi. Kunyanya akakodzera kugadzirwa kwezvipfeko zvisingagadziriswi uye zvikamu zvepamusoro-kupisa. Iko kuvandudza kwekuita-sintered silicon carbide ceramics kwaita basa rakakosha mukusimudzira maindasitiri ekushandiswa kweichi chinhu chinogoneka.
Nzira yechinyakare yekugadzirareaction-sintered silicon carbide ceramicsndeye kushandisa silicon carbide poda yakasanganiswa nekabhoni hushoma hupfu. Musanganiswa unosangana nepamusoro-tembiricha yesiliconization kuita kuti iite dense ceramic material. Nekudaro, iyi mhizha yechinyakare haina zvipingamupinyi zvayo. Iyo sintering process inoratidzwa nekureba kwenguva, kupisa kwakanyanya uye kushandiswa kwesimba kwakanyanya, zvichikonzera kukwira kwemitengo yekugadzira. Sezvo zvinodikanwa zveindasitiri zvesilicon carbide ceramic maumbirwo uye mafomu anowedzera kuoma, izvo zvinogumira zvechinyakare nzira zvinowedzera kuoneka.
Mumakore achangopfuura, kuunzwa kwesilicon carbide nanopowders yave mhinduro inovimbisa yekuvandudza michina yesilicon carbide ceramics. Kushandisa nanopowders kunogona kugadzira ceramics ine yakakwirira sintered densities uye yakakwirira flexural simba. Nekudaro, mutengo wesilicon carbide nanopowder wakakwira, kazhinji unodarika zviuru gumi zveyuan patani, izvo zvinounza chipingamupinyi chikuru pakupararira kwekugamuchirwa uye kugadzirwa kwakakura. Iri dambudziko rehupfumi rinoda kuongororwa kwezvimwe zviwanikwa uye nzira dzekuita kuti kugadzirwa kwesilicon carbide ceramics kuve nyore uye kusingadhuri.
Pamusoro pezvo, kugona kugadzira zvimiro zvakaoma uye zvikamu zvakakura zvinovhura nzira nyowani dzesilicon carbide ceramic application. Maindasitiri anoda dhizaini yakaoma uye yepamusoro-inoshanda zvinhu anogona kubatsirwa kubva kune iyi nzira yekugadzirira. Iyo dhizaini inoshanduka uye yakawanda kugadzirwa kwemhando yepamusoro silicon carbide ceramics inogona kutungamira kubudiriro huru munzvimbo dzakaita seaerospace uye zvemagetsi uko kuita kwezvinhu kwakakosha.
