1. O le a le oneone sima?
O le oneone sima e masani lava ona faia i minerale o loʻo i ai Al2O3 ma SiO2 ma faʻaopoopo i isi mea faʻapitoa. O le oneone fa'ata'amilomilo e faia i le pauta, pelletizing, sintering ma le fa'avasegaina. O lona fausaga tioata autu o Mullite ma Corundum, faatasi ai ma foliga lapotopoto saito, refractoriness maualuga, mautu thermochemical lelei, faalautele vevela maualalo, aafiaga ma abrasion tetee, foliga o le fragmentation malosi. E mafai ona fa'aogaina le oneone sima e maua ai fa'ameamea maualuga e so'o se ituaiga o fa'agasologa oneone.
2. Fa'aoga o le oneone sima
O le oneone sima ua faʻaaogaina faʻapitoa i le faʻavaeina o le tele o ituaiga o tekonolosi faʻapipiʻiina, e pei o le resin coated sand, faʻamaʻaʻaina o le tagata lava ia (F NB, APNB ma Pep-set), pusa malulu, pusa vevela, oneone lolomi 3D, ma le faʻaogaina o le foam. .
3. Le faʻamatalaga o le oneone sima
SND e mafai ona tuʻuina atu oneone sima o faʻamatalaga eseese. Mo vailaʻau vailaʻau, o loʻo i ai le maualuga o le alumini-oxide, oneone alumini alumini-oxide ma lalo ifo o le alumini-oxide oneone, lea e faʻaaogaina e faasaga i mea eseese. O lo'o i ai uma le tele o vaega fa'asoa fa'asoa e fa'amalieina mana'oga o tagata fa'atau.

6. O ituaiga oneone fau
E lua ituaiga o oneone faufale e masani ona fa'aogaina, fa'alenatura ma fa'afu.
O le oneone fa'asolo e masani ona fa'aaogaina o oneone silica, oneone chromite, olivine, zircon, oneone sima ma cerabeads. O le oneone sima ma cerabeads o oneone faufau, o isi o le oneone natura.
