Alumina ceramics, silicon carbide ceramics uye zirconia ceramics

Alumina ceramic iri nyore muzvinhu, yakakura mukugadzira tekinoroji, yakaderera mumutengo, yakanakisa mukuoma uye kupfeka kuramba. Inonyanya kushandiswa mukupfeka-inodzivirira ceramic pombi, mavharuvhu asingapfeke semidziyo yekushongedza, uye anogona zvakare kusungirirwa nematanda kana kunamirwa kumadziro emukati emidziyo yekuparadzanisa senge maindasitiri vertical mill, poda concentrator uye dutu, inogona kupa gumi. nguva dzinopfeka kuramba kwemidziyo yepamusoro. Muzvigadzirwa zvinodzivirira kupfeka, chikamu chemusika chealuminium zvinhu chinogona kusvika pa60% ~ 70%.

Iyo inonyanya kukosha hunhu hweSiC ceramic zvinhu yakanaka yekupisa kuvhundutsa kuramba. Pasi pemamiriro ekupisa kwepamusoro, zvinyorwa zvine zvakagadzikana zvemichina uye zvinogona kushandiswa zvakatsiga pa1800 ℃ kwenguva yakareba. Chimiro chechipiri ndechekuti iyo silicon carbide zvinhu inogona kushandiswa kugadzira zvigadzirwa zvakakura zvine diki deformation. Inonyanya kushandiswa mu preheater inorembera chidimbu chesimende indasitiri, yakakwira tembiricha inodzivirira ceramic nozzle, marasha anodonha pombi uye yakakwirira-tembiricha inotakura pombi yeanopisa magetsi indasitiri. Semuyenzaniso, mhuno dzezvinopisa mumagetsi emagetsi anopisa anonyanya kugadzirwa nesilicon carbide, uye zvigadzirwa zvine hunhu hwekupisa tembiricha kuramba uye kupfeka kuramba. Iyo sintering nzira dzesilicon carbide ceramics dzinosanganisira reaction sintering uye kusagadzikana sintering. Mutengo wekuita sintering wakadzikira, zvigadzirwa zvacho zvine hutsinye, uye kuwanda kwezvigadzirwa zvevacuum sintering zvisina kudzvanywa zvakawandisa. Kuoma kwezvigadzirwa zvakafanana nealumina zvigadzirwa, asi mutengo wayo wakanyanya kukwirira.

Iko kukotama kupikisa kwe zirconia ceramic zvinhu zviri nani pane izvo zve brittle zvinhu. Ikozvino mutengo wemusika we zirconia powder inodhura, iyo inonyanya kushandiswa muminda yepamusoro-soro, yakadai semazino emazino, pfupa rekugadzira, mishonga yezvokurapa, nezvimwewo.
