Abstract
Sintering of Pb(Zr0.53Ti0.47)O3 with a CO2 laser is discussed to indicate the possibility of a new method of synthesizing piezoelectric ceramics. The starting materials are (1) PbO, ZrO2 and TiO2, and (2) Pb3O4, ZrO2 and TiO2. The green oxide pellets are irradiated with a CO2 laser at various powers of 143, 286 and 1857 W/cm2 in a flow rate of 350 cm3/min of O2/Ar(105 Pa). In both cases, the formations of Pb(Zr, Ti)O3 were recognized by XRD (X-ray diffraction) analysis although some starting materials remained at the lower power. The microstructures are also discussed.
