Sinter ndiro chishandiso chinoshandiswa kutakura uye kutakura yakapiswa ceramic embryo muchoto che ceramic.Inonyanya kushandiswa muchoto checeramic semutakuri wekutakura, kupisa kupisa uye kuendesa marara akapiswa.Kuburikidza nayo, inogona kuvandudza kupisa conduction velocity ye sintering plate, kuita kuti sintering zvigadzirwa zvidziye zvakaenzana, zvinobudirira kuderedza kushandiswa kwesimba uye nekumhanyisa kumhanya kwekupfura, kunatsiridza kubuda, kuitira kuti imwe honi yakapfuta zvigadzirwa zvisina ruvara musiyano uye zvimwe zvakanaka.
Corundum mullite zvinhu zvine yakakwira yekupisa kuvhunduka uye kusimba kwekushisa kwakanyanya, uye yakanaka kugadzikana kwemakemikari uye kupfeka kuramba.Naizvozvo, inogona kushandiswa kakawanda pane tembiricha yepamusoro, kunyanya kune sintered magineti cores, ceramic capacitors uye insulating ceramics.
Sintering zvigadzirwa zviri laminated sintering zvigadzirwa.Imwe neimwe layer ye sintering plate pamwe nehuremu hwechigadzirwa ingangoita 1kg, kazhinji l0 layer, saka sintering plate inogona kutakura kumanikidzwa kwakanyanya kweanopfuura makirogiramu gumi.Panguva imwecheteyo, kutakura chisungo kana uchifamba uye kupokana kwekurodha uye kuburitsa zvigadzirwa, asiwo akawanda anotonhora uye anopisa kutenderera, saka, kushandiswa kwezvakatipoteredza kwakanyanya hutsinye.
Pasina kufunga nezvekudyidzana kwezvinhu zvitatu, alumina poda, kaolin uye tembiricha yecalcination zvese zvinokanganisa kupisa kwekuvhunduka uye kukambaira.Iyo yekupisa yekuvhundutsa kuramba inowedzera nekuwedzera kwealumina poda, uye inodzikira nekuwedzera kwekushisa kwekupfura.Kana kaolin iine 8%, kupisa kwekuvhunduka ndiko kwakaderera, kuchiteverwa nekaolin ine 9,5%.Iyo inokambaira inoderera nekuwedzera kwealumina poda, uye inokambaira ndiyo yakaderera kana zviri mukati kaolin iri 8%.Iyo inokambaira inokwira pa1580 ℃.Kuti tipe kufunga nezve kupisa kwekuvhunduka uye kuramba kwezvinokambaira, mibairo yakanaka inowanikwa kana iyo alumina yemukati iri 26%, kaolin iri 6.5% uye tembiricha yecalcination i1580 ℃.
Pane imwe gap pakati pe corundum-mullite particles uye matrix.Uye kune kumwe kutsemuka kwakatenderedza zvimedu, izvo zvinokonzerwa nekusawirirana kweiyo thermal yekuwedzera coefficient uye elastic modulus pakati pezvimedu uye matrix, zvichikonzera microcracks mune zvigadzirwa.Kana iyo yekuwedzera coefficient yezvimedu uye matrix isingaenderane, iyo aggregate uye matrix zviri nyore kupatsanura kana ichipisa kana kutonhora.Gap layer inoumbwa pakati pavo, zvichiita kuti pave nekuonekwa kwe microcracks.Kuvepo kweaya madiki-akatsemuka anozotungamira mukuderedzwa kwemakina zvinhu zvechigadzirwa, asi kana zvinhu zvacho zvichiiswa mukupisa kwekupisa.Mune gaka riri pakati peaggregate uye matrix, inogona kutamba chinzvimbo chebuffer zone, iyo inogona kutora kumwe kushushikana uye kudzivirira kushushikana kwekushushikana pane crack tip.Panguva imwecheteyo, kupisa kwemhepo kunoputika mumatrix kunomira pamukaha pakati pezvikamu uye matrix, izvo zvinogona kudzivirira kupararira kwekuputika.Nokudaro, kupisa kwekushisa kwekushisa kwezvinhu kunovandudzwa.
