Molybdenum boti mafuta sintered mkulu-kutentha kugonjetsedwa chidebe
Pakali pano, opanga mabwato apanyumba amtundu wa molybdenum omwe amagwiritsidwa ntchito pojambula mawaya abwino kwambiri amagwiritsa ntchito timizere toyima tosungunuka ndi timizere ta sintered.
Patatha zaka zingapo tikuchita kupanga mipiringidzo ya molybdenum, tikukhulupirira kuti cholinga chachikulu ndi makhiristo a strip β Ammonium molybdate amakhala ndi zotsatira zabwinoko ngati zinthu zopititsira patsogolo zosungunula zosunthika zomwe zimapangidwa ndikuchepetsa ndi kukanikiza pogwiritsa ntchito ukadaulo wakuwotcha. Pakadali pano, opanga mizere ya molybdenum ku China nthawi zambiri amagwiritsa ntchito izi ngati zinthu zojambulira zingwe za waya molybdenum. Kuphatikiza pa kufufuza kwa kristalo, zomwe zili muzinthu zazikulu monga potaziyamu ndi sodium, zinthu zakuthupi monga porosity ndi kukula kwa tinthu ziyenera kukwaniritsa zofunikira zenizeni ndikusunga bata.
Chisamaliro chapadera chiyenera kuchitidwa pa kutentha kochepa kwa sintering ya billets oponderezedwa. Chifukwa cha brittleness ya molybdenum, ma billets sangathe kuzimitsa mwadzidzidzi kapena kutenthedwa. Mosasamala kanthu kuti sintering kapena kuziziritsa, payenera kukhala malo otchingira kutentha kuti asaphwanyeke. Nthawi ndi kutentha kwa sintering yotsika kutentha ziyenera kuyang'aniridwa bwino, kotero kuti ma billets sangangochotsa zonyansa zochepetsera kutentha, komanso kuwonjezera mphamvu ndi ma conductivity, zomwe zimathandiza kuti vertical melting processing.
Amagwiritsidwa ntchito kwambiri muukadaulo wokutira, mafakitale apamagetsi, uinjiniya wamagetsi, monga vacuum matenthedwe evaporation (boti lopopera evaporation), capacitor sintering, sintering nyukiliya yoyaka moto, zipolopolo za thermocouple, ndi zina zambiri. Ndilo chotengera chopanda kutentha kwambiri chomwe chitha kugwiritsidwa ntchito mu vacuum. ng'anjo ndi magalasi osungunula ng'anjo. Poyerekeza ndi ma crucibles a molybdenum, omwe ali ndi dongosolo losavuta komanso lotsika mtengo, mabwato a molybdenum amagwiritsidwa ntchito kwambiri m'mafakitale opangira kutentha kwa kutentha, monga ng'anjo za vacuum, ng'anjo za ammonia, ng'anjo za mafakitale, ndi ng'anjo zina zotentha kwambiri monga zotengera zakuthupi.
