Tayo sare iyo qiimo aad u fiican, adeeg wanaagsan
Faa’iidooyinka alaabta: iska caabin shooga kaamerada wanaagsan, iska caabin daxalka xoog, xoog cadaadis sare.
sharaxaadda alaabta
Lebenkii cillad-qaabeedka ahaa waxaa sidoo kale loo yaqaan lebenkii arc. Lebenkii arc-sare Alumina waa nooc ka mid ah leben-qaabeeya gaar ah. Qaansada lebenka arc waa wareeg-wareeg ah dhammaadka kalena waa jeexdin. , Waxa kale oo loo dhisi karaa goobada, lebenkan oo kale waxaa loo adeegsadaa laashka. Lebenkii arc waxaa inta badan loo isticmaalaa sida dahaarka gudaha ee baaldiga birta ah. Waxay ahaan jirtay dhoobo. Hadda waxaa si tartiib tartiib ah loogu beddelay lebenkii alumina sare. Lebenkii alumina sare waxaa lagu gartaa iska caabin shooga kaamerada wanaagsan, iska caabin daxalka xoog iyo xoog cadaadis sare.
Lebenkii dib-u-ceshiga ee aluminiumka sare leh waxaa ku jira silicate aluminium leh Al2O3 oo ka sarreeya 48% ilaa 75%. Heerka sare ee aluminiumka, ayaa ka sii fiican tayada lebenkii arc-aluminium-sare. Waa maaddo diidmo ah oo aashito leh, oo ka samaysan waxyaabo aluminium ah oo dabiici ah ama macmal ah (sillimanite, diaspore, alumina sare, iwm). Marka la barbardhigo lebenkii dhoobada ahaa, dib -u -dejintiisu (1750 ~ 1790 ℃) iyo heerkulka jilicsanaanta culeyska (1420 ~ 1500 ℃) ayaa ka sarreeya, iska caabbinta slag -ga iyo xoogga isku -darka ayaa waliba sarreeya.
