AI Technical Summary
Existing lead zirconate titanate-based piezoelectric ceramics exhibit unstable piezoelectric output, high dielectric loss, and insufficient fatigue performance under high-frequency pulse drive and temperature variation conditions, making it difficult to meet the needs of industrial inkjet printing, precision dispensing, and electronic manufacturing.
Through a step-by-step preparation process, lanthanum-anchored lead zirconate titanate powder is first formed, then niobium-zinc is introduced for surface anchoring, and finally bismuth and manganese are added for modification. This ensures that the modified components are deposited on the surface, optimizes the grain boundary and particle contact area, and improves the piezoelectric output and dielectric properties of the material.
It achieves piezoelectric output stability and reduces dielectric loss under high-frequency pulse drive and temperature change conditions, improves the fatigue stability of materials, and is suitable for long-term high-frequency drive scenarios such as industrial inkjet printing, precision dispensing and functional paste deposition.
