Burund Corundum

Faa’iidooyinka badeecada: xoog sare, iska caabin heerkulka sare, iska caabinta daxalka, iyo xasiloonida kiimikada wanaagsan.

sharaxaadda alaabta

Lebenkii corundum ee daahirsanaanta waxay u adeegsadaan corundum tabular iyo corundum fused sida alaabta ceyriin ee ugu weyn, iyada oo loo marayo qiimeynta sayniska iyo macquulka ah, oo lagu daray waxqabadyo aad u fiican, wax-ka-beddelidda cadaadis sare, sintering-heerkulka sare, iyo alaabooyinka dib-u-ceshada waxaa lagu gartaa xoog sare iyo heerkul sare iska caabin. Caabin daxalka iyo xasiloonida kiimikada ee wanaagsan.
