The invention discloses a piezoelectric ceramic process formula which comprises the following steps: material selection, material mixing, primary ball milling, primary drying, pre-pressing, pre-sintering, secondary ball milling, secondary drying, granulation, dry pressing, glue discharging and sintering. The microscopic characteristics of the raw materials can be improved through primary ball milling, the uniformity of the raw materials on the microscopic scale can be improved, full reaction among the raw materials during presintering is facilitated, the microscopic characteristics of the raw materials can be further improved through secondary ball milling, the uniformity of the raw materials on the microscopic scale can be improved, the stability of the piezoelectric ceramic prepared according to the piezoelectric ceramic formula is improved, the quality of the piezoelectric ceramic is improved, the heat-resistant effect of the piezoelectric ceramic can be enhanced by adding zirconium anhydride into the raw materials, and an enamel glaze cover surface can be formed on the surface of the prepared piezoelectric ceramic by adding titanium dioxide into the raw materials. On one hand, the tableting ceramic is prevented from discoloring in long-term use, and on the other hand, the corrosion resistance of the piezoelectric ceramic is enhanced.
本发明公开了一种压电陶瓷工艺配方，包括以下步骤：材料选取、混料、一次球磨、一次烘干、预压、预烧、二次球磨、二次烘干、造粒、干压、排胶和烧结。通过进行一次球磨可以改善原料的显微特征，提高原料在微观尺度上的均匀性，有利于预烧时各原料间充分进行反应，二次球磨可以更进一步的改善原料的显微特征，提高原料在微观尺度上的均匀性，提升压电陶瓷配方所配制的压电陶瓷的稳定性能，提高压电陶瓷的质量，通过在原料中加入锆酸酐可以增强压电陶瓷的耐热效果，通过在原料中加入钛白粉可以在所制得的压电陶瓷表面形成搪瓷釉罩面，一方面防止长期使用中压片陶瓷变色，另一方面增强压电陶瓷的抗腐蚀性。
