Abstract:Ultrafine highly-activated ZrSiO4 powder was synthesized at relatively lower temperature (1 200℃) using monoclinic ZrO2 powder and colloidal SiO2 through the mechanical activation in ball milling. The influence of milling time on the formation rate of ZrSiO4 was studied. When the mixed powder after milling for 120h was calcined at 1200℃ for 2h, the formation rate of ZrSiO4 reached above 95%. The influence of the synthesized ZrSiO4 as an additive to a bonding material for brazing ceramic to metal was also discussed.
Key words: zircon(ZrSiO4) mechanical activation solid synthesis brazing of ceramic to metal
