A method for fabricating composition of a piezo-electric magnet is described that can provide the composition which is sintered at a lower temperature and has high density and strength. The method uses PbO, ZrO2, TiO2, CoO, Nb2O2, SrCO3 each of which has the purity more than 99.5%. Sr is substituted for Pb 5% by mol in the composition of 10Pb(CO1/3/Nb2/3)O3-45PbTiO3-45PbZrO3 and then WO3 of 1% by weight is added to the composition prior to being mixing. Thereafter, over-quantity of PbO is added thereto while grinding and then an sintering process is performed. Thereby, it is possible to composite the piezo-electric magnet having high density and strength at relatively lower temperature. |
