Piezoceramic for Piezocomposite Fabrication Method thereof

摘要

The present invention relates to a piezoelectric ceramic manufacturing method for a piezoelectric composite having a high volume fraction or high aspect ratio and having a small cross section. The present invention comprises the steps of mixing and assembling the carbon block binder in the injected PZT piezoelectric block binder to form one unit particle; Bonding the unit particles to isothermal pressure compression to mutually bond each other; Assembling one or more of the unit particles to each other to form one unit unit; Bonding the unit units by isothermal heat compression to mutually bond each other; Sintering one unit block having a predetermined number and size by assembling and heating and compressing the unit units into one or more; Attaching the support plate to the pillar of the unit block below, and heating and compressing the block to complete the block composite; And applying heat to the block composite to vaporize and then sinter the PZT piezoelectric block binder and the carbon block binder to leave only the PZT piezoelectric block binder, thereby completing a piezoelectric ceramic for piezoelectric composite. Disclosed is a method for manufacturing molten piezoceramic.
