Nano magnesium oxide ndiyo yakajairika alkaline oxide.Nekuda kwekunyungudika kwayo kwe2800 ° C uye zvimwe zvakakosha uye zvakanakisa zvivakwa, inogona kushandiswa mune yepamusoro Ceramic munda.Panyaya yekushandiswa, inogona kukamurwa kuita nzira mbiri: yakananga sintering mumakeramiki uye shandisa seyamuro yekupisa kune mamwe ma ceramics.
Direct sintering muCeramics
Nano magnesium oxide yakanakisa ceramic mbishi zvinhu.Nekuda kwekunaka kwayo kupisa uye kuramba kwakasimba kwekukukurwa nealkaline metal solutions, magnesium oxide ceramics inowanzokodzera kune yakanyanya tembiricha nharaunda.Inogona kushandiswa se crucible yekunyungudutsa simbi, uye mune atomic simba indasitiri inokodzerawo kunyungudutsa yakakwirira-kuchena uranium uye thorium.Inogonawo kushandiswa sevhavha yekudzivirira ye thermocouples.Nekuti ine chivakwa chekubvumidza mafungu emagetsi kuti apfuure, inogona kushandiswa sechivharo cheradar uye chiratidziro chewindow zvinhu kune infrared radiation.Iri zvakare raw material ye piezoelectric uye superconducting zvinhu, uye ine hushamwari kwezvakatipoteredza uye inoshingirira kutungamira corrosion.Inogonawo kushandiswa seceramic sintering carrier, kunyanya yekudzivirira sintering yezvigadzirwa zveceramic zvakadai se β-Al2O3 ine zvinhu zvinoparadza uye zvinopisa pakupisa kwakanyanya.
Inoshandiswa seyamuro yekupisa kune mamwe ma ceramics
Nano magnesium oxide inogonawo kuwedzerwa kune gadziriro yezvimwe zviumbwa, izvo zvine mhedzisiro yakanaka pakudzikisa tembiricha yegirazi, kudzikisa tembiricha yekupisa, uye kuvandudza maoptical uye mechanic zvivakwa zveceramics, nekudaro zvinotibatsira kuwana emhando yepamusoro zvinhu zveceramic. .
Semuyenzaniso, silicon nitride ceramics yave imwe yeanonyanya kuvimbisa-yepamusoro-tembiricha zvimiro nekuda kwesimba rawo repamusoro-tembiricha simba, kupisa kutyisa kuramba, uye kugadzikana kwemakemikari.Nekudaro, iyo yakasimba covalent chisungo uye yakaderera diffusion coefficient inoita kuti zviome kuita sinter densification.Kuwedzerwa kwe magnesium oxide kunogona kuita ne silica pamusoro pesilicon nitride poda panguva yekupisa kuti iite silicate fluid chikamu, iyo inogona kusimudzira kunyura kwesilicon nitride ceramics.Parizvino, MgO-Y2O3 composite sintering aids inowanzo shandiswa kuwana mhepo yekumanikidza sintering yesilicon nitride ceramics.
Muchidimbu, nano magnesium oxide inoita basa rakakosha mumunda weceramic.Inogona kuita sechinhu chakakosha kana chekuwedzera kuvandudza mashandiro uye mashandiro eceramics, nekudaro ichisimudzira kufambira mberi nekusimudzira kweindasitiri yeceramic.
