Method of manufacturing dielectric ceramic compositions of lead-based perovskite |
| 摘要 |
A manufacturing method for dielectric ceramic compositions of lead-based perovskite containing lead magnesium tungstate [Pb(Mg1/2W1/2)O3] as a component which is characterized in that magnesium tungstate powder [MgWO4] is used as a starting material instead of MgO and WO3 powder.
