Kupereka kwa Nano Magnesium Oxide mu Ceramic Field

Nano magnesium oxide ndi mchere wamba wa alkaline oxide.Chifukwa cha kusungunuka kwake kwa 2800 ° C ndi zinthu zina zapadera komanso zabwino kwambiri, zitha kugwiritsidwa ntchito m'munda wapamwamba wa ceramic.Pankhani yogwiritsira ntchito, itha kugawidwa m'njira ziwiri: kuyika molunjika muzoumba ndikugwiritsa ntchito ngati chothandizira chopangira zitsulo zina.

Direct sintering mu ceramics

Nano magnesium oxide ndi yabwino kwambiri ceramic zopangira.Chifukwa cha kukana kwabwino kwa kutentha komanso kukana kwambiri kukokoloka ndi njira zazitsulo zamchere, magnesium oxide ceramics nthawi zambiri imakhala yoyenera kumadera otentha kwambiri.Itha kugwiritsidwa ntchito ngati chitsulo chosungunula zitsulo, komanso mumakampani opanga mphamvu ya atomiki ndi oyeneranso kusungunula uranium ndi thorium.Itha kugwiritsidwanso ntchito ngati manja oteteza ma thermocouples.Chifukwa ili ndi mwayi wololeza mafunde a electromagnetic kudutsa, imatha kugwiritsidwa ntchito ngati chophimba cha radar komanso mawindo owonetsera ma radiation a infrared.Ndiwopangira zida za piezoelectric ndi superconducting, ndipo ndi zachilengedwe komanso zosagwirizana ndi dzimbiri.Itha kugwiritsidwanso ntchito ngati chonyamulira cha ceramic sintering, makamaka pachitetezo cha sintering cha zinthu za ceramic monga β-Al2O3 zomwe zimakhala ndi zinthu zowononga komanso zosasinthika pakutentha kwambiri.

Amagwiritsidwa ntchito ngati chothandizira chopangira zida zina za ceramic

Nano magnesium oxide ikhoza kuwonjezeredwa pokonzekera zoumba zina, zomwe zimakhudza kuchepetsa kutentha kwa galasi, kuchepetsa kutentha kwa sintering, ndi kukonzanso maonekedwe ndi makina a ceramics, potero kutithandiza kupeza zipangizo zamakono zamakono. .

Mwachitsanzo, zitsulo za silicon nitride za ceramic zakhala chimodzi mwazinthu zopangira kutentha kwambiri chifukwa cha mphamvu zake zotentha kwambiri, kukana kugwedezeka kwa kutentha, komanso kukhazikika kwa mankhwala.Komabe, chomangira chake cholimba komanso chocheperako chocheperako zimapangitsa kuti zikhale zovuta kuti sinter densification.Kuwonjezera kwa magnesium okusayidi akhoza kuchita ndi silika pamwamba pa silicon nitride ufa pa sintering kupanga silicate madzi gawo, amene angathe kulimbikitsa sintering wa pakachitsulo nitride ziwiya zadothi.Pakadali pano, zida za MgO-Y2O3 zophatikizika za sintering nthawi zambiri zimagwiritsidwa ntchito kuti akwaniritse kuthamanga kwa mlengalenga kwa silicon nitride ceramics.

Mwachidule, nano magnesium oxide imagwira ntchito yofunika kwambiri m'munda wa ceramic.Itha kukhala ngati chinthu chofunikira kapena chowonjezera kuti chiwongolere magwiridwe antchito ndi magwiridwe antchito a ceramic, potero kulimbikitsa kupita patsogolo ndi chitukuko cha mafakitale a ceramic.
