Alumina Ceramic, dzimwe nguva zvinonziAluminium oxide (Al2o3) or Alumina, inhau yeindasitiri ndeye ceramic iyo inogadzirisa kwazvo uye inosimba zvakanyanya. Nekuda kwehunhu hwavo,Alumina Ceramicsvari pakati pemamwe maCereracs anozivikanwa ekudzora, kupfeka, uye marongero. Kazhinji yakagadzirwa kubva kuBauxite, Alumina Cereracs inogona kuumbwa nekuwedzera, kuumbwa kuumba, kufa kudzvanya, kutsvedza, kutsvedza, uye madhaimani ekumhanya.
Mulliteinogadzirwa nekukasira silica uye alumina mune dzakasiyana musanganiswa panguva yekuchinjisa, kugadzira zvinhu zvakasiyana siyana. Kune dense solids, inonzi mullite; yemamakisi ekupora, inonzi porous mullite kana corundu.
Kune maviri marudzi emhando dze synthetic mullite (Al2o3-Sio2) zvigadzirwa: PORORORT uye usingakwanise kuita mafomu. Simba rakakwirira uye rakasiyana nekukasira kuparadza kuvhunduka kwakasanganiswa mune zvakazara kutadza kutadza (kukwana) mullite. Pousus mullite's low's yakaderera yekuwedzera kuwedzera uye yakaenzana simba inopa yakagadziriswa mazinga ekuvhundutsa
Mullite ceramicsvanoshandirwa mumagetsi emhepo, mafuro, vahedheni, uye vanopfeka zvinoshandiswa uye zvekushora-tsika nekuda kwekuvhunduka kwavo kwekushamisika kwekusvika kwavo kusvika pamakore makumi matatu nemashanu.
Kiyi yezvinhuAlumina:
Tembiricha kugadzikana

Insulation yemagetsi emagetsi
Chimiro uye kuumbwa
Aluminium oxide (Al2o3)Nekuchenesa mazinga kubva pamakumi manomwe neshanu muzana kusvika kupfuura 99% ndiyo yakakosha ingano inoshandiswa kugadzira alumina ceramics. Kuomesa uye kupfeka kurwisa kuwedzera neAlumina Constrenration. Iyo crystalline chimiro inopa inoshamisa kusimba kusimba uye mechan simba.
Izvo zvinhu zvinogadziramullite ceramicsis aluminium silte (3alo3·2SiO2). Ivo vanowanzogadzirwa nekukwirisa kupisa kweSilica uye Alumina, iyo inoburitsa chimiro chakareruka neyekumusoro kugadzikana kwekunyora. Kuregererwa kwaMulice kune yekudziya kushamisika uye kushoma kupisa kwekuwedzera kunoita kuti ive yakakosha.

AluminaSepsion abasion kupesana kunoita kuti ive yakakwana yekucheka zvishandiso uye kudzivirirwa kwekudzivirira.
Mullite'S BLASTIONAL HURE Hunhu uye Simba (6-7 Mohs kuomarara) Ita sarudzo yakanaka yeinjiniya yeinjiniya uye yegirazi.
Michina yezvivakwa
Aluminainozivikanwa kwazvo nekuomerwa kwayo kunoshamisa, simba rakanyanya rekumanikidza, uye rakakura kupfeka kuramba. Aya maitiro anozviita sarudzo yakanaka yekupfeka zvigunwe, achiseka midhiya, uye yakakwirira-mutoro maficha aropi kuti ave hanya zvikuru.
Mullitehaina kuoma kupfuura alumina, asi inopa simba rakakwana remakaniki pese paunenge uchiderera uremu. Hunhu hwayo hunoki hwakaringana nekugona kwayo kudzivisa kutonhora kukuru kwekupisa.
Inopisa uye yemakemikari kuramba
Alumina Ceramicsinogona kuramba kupisa kwakanyanya kwekushandisa uchiramba uchiramba wakarongeka munzvimbo dzakasimba. Ivo zvakare vanoramba zvakanyanya kuAcids neAlkalis, vachiita kuti vave vakakwana pamakemikari ane hutsinye.
MulliteCereracs anomira zvisingaite kune yavo yakakwirira yekukwira inovhundutsa kudzikisira uye yakaderera yekubata. Ivo vanoshanda zvinobudirira mumidziyo yakakwirira-tembiricha, Kiln Linnings, uye maficha ekuratidzira ipo ipo yekudyara inoitika kazhinji.
