Method for preparing high-density PZT ceramic through powder slurry pouring
The invention discloses a method for preparing PZT ceramic, and aims to provide a method for preparing high-density PZT ceramic through powder slurry pouring, wherein the method is uniform in material structure, high in density, simple in production process, easy to operate and control, high in production efficiency and low in production cost. According to the technical scheme, the preparation method comprises the following steps: uniformly mixing Pb3O4, ZrO2 and TiO2, and respectively preparing PZT porcelain with Zr/Ti = 0.92, 1, 1.08, 5.67 and 19 by adopting a solid phase method; adding deionized water and a dispersing agent, mixing, and carrying out ball milling until the particle size is less than or equal to 200 microns; adding a binder, uniformly stirring, injecting into a mold under pressure, molding, demolding, and drying to obtain a green body of which the relative density is greater than 50%; heating the green body to 400-750 DEG C at the rate of 0.5-1 DEG C/min, and discharging the rubber for 4-6 hours; and heating to 1200-1300 DEG C at a rate of 3-5 DEG C/min, and carrying out lead-buried sintering for 1-4 hours to obtain the PZT ceramic.
本发明公开了一种PZT陶瓷的方法，旨在提供一种材料组织均匀、致密度高，且生产工艺简单、易于操作控制、生产效率高、生产成本低的粉浆浇注制备高致密度PZT陶瓷的方法。其技术方案是：将Pb3O4、ZrO2、TiO2混合均匀，采用固相法分别制备成Zr/Ti＝0.92，1，1.08，5.67，19的PZT瓷料；加入去离子水、分散剂混合，球磨至粒径≤200μm的浆料；加入粘结剂，搅拌均匀后压力注入模具，成型后脱模、干燥，得相对密度大于50％的生坯；将该述生坯以0.5～1℃/min的速率升温至400～750℃，排胶4～6小时；然后以3～5℃/min的速率升温至1200～1300℃，埋铅烧结烧结1～4小时，得PZT陶瓷。
