The technology for the preparation of the PMN based dielectric powder for MLCC by the Molten Salt Synthesis process is investigated The PMN based dielectric powder for MLCC with 100% Perovskite phase is successfully prepared The PMN based dielectric powder produced by the Molten Salt Synthesis process is active and can be roasted at 700℃, and can be applied with low Pd content or pure silver paste, so the production cost of MLCC is able to reduced The particle size distribution, the microstructure, and the dispersion of the PMN based dielectric powder produced by the Molten Salt Synthesis process are homogeneous, excellent and intensive The production flow sheet and period of the Molten Salt Synthesis are short, so the operation cost is low
