| titleOfInvention | Lead-free piezoelectric ceramic and preparation method thereof |
| abstract | A lead-free piezoelectric ceramic and a preparation method thereof mainly relate to the field of piezoelectric ceramics. The lead-free piezoelectric ceramic has good piezoelectric property, stable resonance frequency within the range of-20 to 80 ℃, lower frequency temperature coefficient, no lead and environment-friendly material, can be used in occasions with high requirement on the stability of the resonance frequency; when the low-temperature sintering powder is prepared in the preparation method, the matrix ceramic powder and the low-temperature sintering aid are respectively synthesized, the particle size is controlled through the ball milling condition, and then the matrix ceramic powder and the low-temperature sintering aid are mixed for heat treatment and ball milling to obtain the low-temperature sintering powder. Therefore, the lead-free piezoelectric ceramic and the preparation method thereof have important popularization and application values. |
