  • Abstract
    Suppression of temperature variation and improvement of surface roughness on filter materials were accomplished by using hot-pressed piezoelectric ceramics consisting of ternary complex ceramics, PbTiO3and PbZrO3, and a compound Pb(Mn1/3Nb2/3)O3. The electromechanical coupling factor kswas 0.239, temperature variation of wave velocity TVs, was 17 ppm/°C, and average pore size was 1.5 µm. The ceramics obtained are suitable for such practical devices as surface-wave filters.
