摘要: Abstract This study investigates the high temperature chemical resistance of zircon, ZrSiO 4 , against Na 2 O, CaCO 3 PbO, ZnO, Fe O V 5 and CeO . It was observed that lead sodium oxides react with zircon only at 700 850 °C respectively, while others do not over range examined. Surprisingly, if PbO are present same time, reaction is inhibited does suffer degradation. On other hand, ternary mixture –PbO–Na reacts slightly confirmed by XRD after thermal treatment mixtures 650 °C FTIR 700 °C revealing formation silicates zirconates. Not all reactions between destructive suggest a suitable material for production diesel ceramic filters.
