I Finally Tried Piezo Plates And Blocks For A Week And This Is What Happened

              I Finally Tried Piezo Plates And Blocks For A Week And This Is What Happened


particle size of raw material PZT piezo ceramic powder is 500 nm, conductivity of ethanol deionized water is≤ 10μS cm-1. Preparation of PZT piezoelectric ceramics transducers PZT powders were press-molded at 15 MPa to form 50 mm × 6 mm × 6 mm spline and φ30 mm × 2 mm lamellar ceramic membranes. After drying at room temperature is 12 h, the samples were fired at 900, 950, 1000, 1050 and 1100 °C, respectively. Characterization of porous PZT piezoelectric materials piezo crystal is membranes .The microstructure of porous PZT ceramic membranes was characterized by scanning electron microscopy. The bending strength of porous PZT piezoelectric ceramic membranes was measured by three-point flexural strength using tensile testing machine. The method of porous PZT pickup piezo transducer . The average pore size and distribution of porous PZT piezoelectric ceramic membrane were determined by automatic mercury porosimetry. Porous porous PZT piezoelectric ceramic membrane was prepared by laboratory self-made porous ceramic membrane test platform under the operating pressure of 0.1 MPa Permeability of electric ceramic membrane.
