摘要:
The study on laser sintering of Ba(Ti0.95Zr0.05)O3 (BZT) piezoelectric ceramics was introduced. The powder of BZT was prepared by traditional ways. The green patch was sintered by the carbon dioxide laser which the maximum laser power was 150 W, the scanning speed was 1440 rad/min and the sintering time was 10 min. The piezoelectric ceramics character of BZT ceramic was showed through measuring the dielectric constant-temperature and impedance-frequency data. The ceramic sample by laser sintering had higher Curie temperature through comparing the values of dielectric constant-temperature from traditional ways and laser sintering respectively. It was found that Ε=1563, d33=45 pC/N. The data of XRD showed that the two peak values [(111), (002)] had been enlarged and it was observed that the crystal grain had grown in the ceramics. The measure of laser sintering could be regarded as one of the ways to sinter functional ceramics.
