Umusanzu wa Nano Magnesium Oxide mu murima wa Ceramic

Okiside Nano magnesium ni okiside ya alkaline isanzwe.Bitewe nubushyuhe bwo hejuru bwa 2800 ° C hamwe nibintu bidasanzwe kandi byiza, birashobora gukoreshwa mumurima wubutaka bwateye imbere.Kubijyanye no kubishyira mu bikorwa, birashobora kugabanwa muburyo bubiri: gucumura neza mubutaka no gukoresha nkubufasha bwo gucumura kubindi bikoresho byubutaka.

Gucumura mu buryo butaziguye

Nano magnesium oxyde ni ibikoresho byiza bya ceramic.Kubera ubushyuhe bwayo bwiza no kurwanya isuri ikoresheje ibyuma bya alkaline, ceramics ya magnesium oxyde ikunze kuba ahantu hashyuha cyane.Irashobora gukoreshwa nkibyingenzi mu gushonga ibyuma, kandi mubikorwa byingufu za atome biranakwiriye gushonga uraniyumu na thorium.Irashobora kandi gukoreshwa nkintoki ikingira thermocouples.Kuberako ifite umutungo wo kwemerera imiyoboro ya electromagnetic kunyura, irashobora gukoreshwa nkigifuniko cya radar hamwe nibikoresho byamadirishya byerekana imirasire yimirasire.Nibikoresho fatizo kubikoresho bya piezoelectric na superconducting, kandi byangiza ibidukikije kandi birwanya ruswa.Irashobora kandi gukoreshwa nkigikoresho cyogukora ceramic, cyane cyane kurinda ibicuruzwa byibumba nka β-Al2O3 bifite ibintu byangirika kandi bihindagurika mubushyuhe bwinshi.

Ikoreshwa nkimfashanyo yo gucumura kubindi bikoresho byubutaka

Okiside ya Nano magnesium irashobora kandi kongerwa mugikorwa cyo gutegura andi mafumbire, bigira ingaruka nziza mukugabanya ubushyuhe bwikirahure, kugabanya ubushyuhe bwa sinteri, no kunoza imiterere ya optique na mehaniki yubutaka, bityo bikadufasha kubona ibikoresho byiza byubutaka bwiza. .

Kurugero, silicon nitride ceramics yabaye kimwe mubikoresho byizewe byubushyuhe bwo hejuru cyane kubera imbaraga zubushyuhe bwo hejuru cyane, guhangana nubushyuhe bwumuriro, hamwe n’imiti ihamye.Nyamara, imiyoboro ikomeye ya covalent hamwe na coefficient de diffuzione ituma bigora gucumura.Kwiyongera kwa okiside ya magnesium irashobora kwitwara hamwe na silika hejuru yifu ya silicon nitride mugihe cyo gucumura kugirango ikore feri ya silicike, ishobora guteza imbere gucumura kwa silicon nitride ceramics.Kugeza ubu, MgO-Y2O3 ibikoresho bifasha gucumura bikoreshwa muri rusange kugirango bigere ku muvuduko ukabije w’ikirere cya silicon nitride ceramics.

Muri make, nano magnesium oxyde igira uruhare runini mumurima wubutaka.Irashobora gukora nkibikoresho byibanze cyangwa inyongeramusaruro kugirango itezimbere imikorere nimikorere yububumbyi, bityo biteze imbere niterambere ryinganda zubutaka.
