SUGGESTION FOR SOLDERING WIRE LEADS TO OUR CERAMICS: 
The average Curie temperature for our Piezo ceramics is around 250°C. For soldering small items, the soldering method we suggest is: use at least 2% Silver content solder material, and the soldering temperature should be 250°C-270°C within 2 seconds. Longer than that it may cause the transducer to loose its Piezoelectric properties as well cause the Silver electrode to peel off.
We offer a Lead free solder material that can be found HERE
