Astaamaha

Khafiifinta sawirku waa nooc ka mid ah heerkulka sare ee heerkulka sare laga sameeyay oo laga sameeyay silicon-silicon-ka silicon-ka, oo lagu soo saaray hanaanka isku-dhafka ah ee is-riixitaanka iyo daaweynta heerkulka-sare. Khafiifkan ayaa noqday aalad muhiim u ah meelaha beeraha ah sida birta qarka u saaran iyo soosaarka dhoobada sababtuna tahay dhismaheeda jirka iyo kiimikada ee gaarka ah.

  1. Hormalka kuleylka
    • Claphite CruciblesBandhigay fal heer sare ah oo heer sare ah, hubinta isugeynta kuleylka labiska. Hoygani wuxuu yareeyaa dhibco kulul oo hubiya xitaa dhalaalid, iyaga oo ka dhigaya mid aad u hufan oo ku habboon biraha sida dahabka, naxaas, iyo aluminium.
    • DIIWAANGALINTA QARSOODKA waxay gaari kartaa qiimayaal illaa 100 w / m · k, kaas oo ka sarreeya marka loo eego qalabka dhaqameed dhaqameed.
  2. Caabbinta heerkulka-heerkulka
    • Claphite Crucibleswaxay awood u leeyihiin heerkul aad u sarreeya, ilaa 1700° CIntert of bethopheres ama xaaladaha vacum. Tani waxay u oggolaaneysaa iyaga inay ilaashadaan sharafdarro qaab-dhismeed ah oo ku saabsan bay'ad wax ku ool ah oo aan sharaf lahayn.
    • Cruciles-kaasi waxay xasilloon yihiin oo u adkaystayaan ciladaha kulaylka daran.
  3. Isugeynta hooseeya ee ballaarinta kuleylka
    • Qalabka garaafka leh ayaa leh aIsugeynta hooseeya ee ballaarinta kuleylka(Sida hoose ee 4.9 x 10 ^ -6 / ° C), yareynta halista dillaaca ama naxdinta kuleylka marka aad ku dhacdo isbeddelo heerkulka degdegga ah.

  6. Daahirnimada iyo walxaha dharka
    • Kalluunka hufan ee daahirsanaanta(Illaa 99.9% daahirnimo) waxay muhiim u tahay codsiyada meesha faddaraynta birta ay tahay in laga fogaado, sida soo saarista bir qaali ah ama dhoobada sare.
    • Isku-dhafka Silicon Carbide CaphidesIsku dar sifooyinka labada shahaadada iyo silicon carbide, oo bixiya xoogga farsamada gacanta, iska caabbinta oksigation, iyo dhibic dhalaalaysa, oo ku habboon xaaladaha hawlgalka ee xad dhaafka ah.
  7. Cimri dherer iyo cimri dheer
    • Si aan caadi ahayn u riixaya khudradda garaacistawaxaa loo soo saaray si ay u yeeshaan cufnaanta labiska iyo xoog, taasoo keenta in noloshu dheer iyo waxyaabaha la dhimay ee lagu guuldaraysto inta lagu jiro hawlgallada heerkulka-sare. Cruciles-yadaas sidoo kale waxay u adkaysan karaan nabaad-guurka iyo waxyeelada farsamada.

  8. Halabuurka kiimikada:

    • Kaarboon (c): 20-30%
    • Silicon Carbide (Sic): 50-60%
    • Alumina (al2o3): 3-5%
    • Kuwa kale: 3-5%
  9. Cabirrada loo yaqaan 'lezes' iyo qaabab
    • Isku-dhafkayaga garaacisyada ah ayaa lagu heli karaa tiro badan oo kala duwan iyo qaabeyn. KaQulqulka yar-yar ee digniinta yar(Ku habboon tijaabada birta ee shayga ah) ilaa khudbadaha waaweyn ee loogu talagalay in lagu qoro warshadaha, waxaan bixinaa xalal ku habboon codsi kasta.
    • Canjiraadka garaacistaiyo iskutallaabtuku shub tuugadaSidoo kale waxaa loo habeyn karaa shuruudaha gaarka ah ee lagu tuuro, hubinta ku habboonaanta iyo hufnaanta birta gacanta.
