The experimental results show that the improved microwave sintering technique can control the volatilization of PbO to improve the remove of the pore,so can gained the fine uniform crystal and high dense PLZT ferroelectrics ceramics.

• 结果表明，通过对微波烧结工艺的改进能够有效控制烧结过程中PbO的挥发，促使样品中气孔的充分排出，从而有利于获得晶粒细小均匀并具有较高致密度的PLZT铁电陶瓷。
