Vacuu Fa'asa'o Otometi Atoa'a maualuga...
O le ogaumu fa'a'ave'ave'a ose ogaumu e fa'aogaina ai le fa'avevela fa'atosina e fa'amalu ai mea fa'avevela.O le ogaumu faʻapipiʻi faʻapipiʻiina o se seti atoatoa o meafaigaluega mo faʻapipiʻi faʻapipiʻi carbide faʻapipiʻi ma paʻu uʻamea eseese e ala i le faʻaogaina o le faʻaogaina o le faʻavevelaina o le faʻavevela faʻavave i lalo ole vacuum poʻo le puipuiga o le siosiomaga.Ua mamanuina mo le gaosiga o alamanuia o u'amea malo, uamea dysprosium ma mea sima.

Ogaumu Graphite maualuga
O le ogaumu graphite o se masini faʻapisinisi e mafai ona fai graphite mai maʻa eseese ma vailaʻau.E mafai ona faʻaaogaina e gaosia ai mea graphite ma le maualuga, maualuga le faʻatinoina ma le malosi o le eletise.E tele ituaiga o ogaumu graphite, ituaiga vaalele masani, tūsaʻo, ituaiga faʻamalolo, ituaiga vai ma isi.

Ogaumu Tuputupu Crystal Tasi
O le ogaumu tioata tasi e taʻua foi o le ogaumu tioata mono, o se masini e faʻafefeteina mea polycrystalline e pei o le polysilicon ma graphite heaterin se kasa inert (nitrogen and helium gas) siosiomaga ma tuputupu aʻe tioata tasi e aunoa ma le dislocation e ala i le faaaogaina tuusao-toso auala.

Polysilicon Ditrctional Solidificatiion Ogaumu
O le ogaumu faʻamalosi faʻatonuga o se meafaigaluega faʻaonaponei o loʻo galue mo le faʻafefeteina o uʻamea poʻo le uʻamea faʻatasi ai ma le faʻavevelaina o le faʻavevela faʻavavevave i lalo ole vacuum, faʻapipiʻiina le faʻaogaina o le vevela faʻatasi ma le ogaumu faʻapitoa faʻapitoa ma le faʻamafanafanaina, ma sauniuni mo le faʻamaʻaina ma le tioata tasi e ala i le toso i lalo masini.E mafai ona pulea lelei le vevela ma mea faʻapipiʻi mea.Ina ia maua le maualuga o le vevela gradient ma lamolemole solidifying interface, e faʻaaogaina ma faʻapitoa faʻailoga i lona manaʻoga mo le vevela gradient.O la matou ogaumu fa'amalosi fa'atonu ua fa'ata'atia i se ala tu'usa'o ma se vaega la'ititi o lo'o galue i totonu o faleaoga.

Ogaumu fa'alili fa'ameamea
Vacuum Induction Melting (VIM) o le faʻafefeteina o le uamea e ala i le faʻaogaina o le eletise i lalo ole masini.O se ogaumu fa'aoso o lo'o i ai se fa'alava fa'amaufa'ailoga e si'osi'omia e se vili fa'aoso o lo'o tu'u i totonu o se potu vacuum.O le ogaumu fa'aulu e feso'ota'i le puna eletise i se taimi e fa'atatau tonu i le tele o le ogaumu ma mea o lo'o fa'afefeteina.
