説明
Influence of SiO2 addition on formation process of Pb(Ti⋅Zr)O3 solid solution was studied. Powdered PbO, TiO2, ZrO2 and SiO2 were used as raw materials. The process was determined from the variation of X-ray diffraction patterns and that of dilatometric dimensional change with heating temperatures.<BR>If the materials excluding SiO2 were mixed, Pb(Ti⋅Zr)O3 was synthesized, passing through formations both of PbTiO3 and PbZrO3. However, when the materials including SiO2 were mixed, the PbZrO3 formation was suppressed, accompanying by a decrease of Pb(Ti⋅Zr)O3 formation temperature.<BR>The difference seems to be caused by the appearance of a liquid phase formed by the co-existence of SiO2 and PbO, which occurs during the Pb(Ti⋅Zr)O3 formation process. Reaction observed at the contact surface of two green compacts, consisting of SiO2-PbO as well as of Pb(Ti⋅Zr)O3, was in line with the assumption.
