Hot Press Sintering in AlN Ceramic

                                                  (Hot press sinteredAlNyakagadzirwa neWintrustek


Hot press sintering ndiyo nzira yekuisa ceramic pasi pekumanikidzwa kwakati. Inobvumira kudziya panguva imwe chete uye kudhindwa kuumbwa kweceramics kuti ibudise zvinhu zvine tsanga yakanaka, kusimba kwepamusoro, uye masimba akasimba emuchina.


Kutsikirira kunopisa kwakanyatso kuenderana nekugadzirwa kweakanyanya-yepamusoro tembiricha ceramics (UHTCs), zvinova zvinhu zvisingawanzo svina kusvika kune yakanyanya kusimba mukushanda kwakajairwa kunyura.


Kwemakore, vatsvakurudzi vakaedza nzira dzakawanda dzekuita sinteringAlNuye kuwedzera maitiro ayo.AlNinoratidza covalent bonding, saka, kuti uwane kuzara kwakazara, inofanira kunyungudutswa patembiricha inodarika 1800 ℃. Kupisa kudzvanya saka kunoshandiswa muindasitiri ku sinterAlNpasina sintering additives.


Hot-press sintering inzira inowanzo shandiswa yekusimudzira simba reAlN ceramics nekuda kweaya maficha. Chekutanga, kudzvinyirirwa-kubatsirwa densification kunoitwa pamwe chete nekupisa-pressing sintering process kubatsira mukugadzirwa kweakazara densified AlN ceramics. Kudzvinyirirwa kwekunze kunopa densification imwe simba rekusundidzira kana ichienzaniswa nekudzvanyirira kusinga dhindikidzi, kudzikisa tembiricha yekunyura neinosvika 50-150 ℃ uye kudzikisira kuumbwa kwezviyo hombe.


Hot-pressed aluminum nitride ceramic inoshandiswa mu semiconductor industry inoda simba rakasimba remagetsi, kusimba kwepamusoro-soro pamwe chete nekugona kupisa kwemafuta.
