Cov khoom thiab cov yam ntxwv ntawm zirconium corundum cib
Zirconium corundum cib yog ib hom refractory cib ua los ntawm industrial alumina thiab zircon xuab zeb. Raws li cov txheej txheem tsim, zirconium corundum cib tuaj yeem muab faib ua ob hom fused zirconium corundum cib thiab raug rho tawm haujlwm zirconium corundum cib.
Fused zirconium corundum cib feem ntau hu ua dawb hlau cib, tseem hu ua corundum - kab pheeb ces kaum zircon cib. Lub ntsiab chemical muaj pes tsawg leeg Al2O3 50% ~ 70%, ZrO2 20% ~ 40%, tus so yog SiO2. Lub ntsiab ntxhia muaj pes tsawg leeg yog plagiozircon (ZrO2), corundum (-Al2O3) thiab iav theem. ZrO2 muaj lub siab melting point (2715 degree), tshuaj zoo stability, thiab muaj zog corrosion kuj rau acidic thiab alkaline xov xwm, tshwj xeeb tshaj yog kua iav.
