1.Study on Corrosion Resistance of Zircon AZS-Bonded Ramming Mix Used for Glass-Kiln
2.The research developed a kind of whitening agent with the main materials of zircon, metakaolin, and CeO.
3.The Decomposition of Zircon and the Reaction of Aluminum Oxide in AZS Bonding Materials
4.On the basis of the data referred to, the additives as Nd2O3 , Al2TiO5 , Li2SiO3 ,ZiSiO3 , CeO are used in the study,while adding Li2SiO3 in MgO-Al2O3- SiO2 -ZrO2 system and GeO in MgO - Al2O3 - SiO2. As a result ,many performances of cordierite were improved by adding these compound additives.
5.The experiments showed that the amount of zircon, metakaolin, and CeO added and their proportion affected the whitening effect.
6.The corrosion resistance performances of natural white afrodite, electric cast quartz bricks, sintered alumina, electric cast AZS and sintered zircon in molten glasses for high-strength fiber drawing at high temperatures (1400～1500℃) have been studied.
7.A dense alumina and a chrome refractory had the lowerst melt-line corrosion rate in the iron phosphate melts,whereas the corrosion rate for silica,zircon,and alumina-zirconia-silica(AZS)refractories was somewhat high.
8.A dense alumina refractory and a chrome refractory had the lowest meltline corrosion rate in the iron phosphate melts, whereas the corrosion rate of silica, zircon, and aluminazirconiasilica(AZS) refractories was somewhat high.
9.The erosion resistances of 5 kinds refractories:electric cast quartz bricks,natural white afrodite, sintered pure alumina, AZS bricks and zircon bricks, in molten glass have been tested by the way of static immersion method, the results obtained show that alumina bricks are suitable to be used as furnace lining for irradiation - resistant insulation glass fiber production.
