Nano-Size Lead-Free Piezoceramic Powder and Method of Synthesizing the Same

摘要

A nano-size lead-free piezoceramic powder and a method of mechanochemically synthesizing the same are provided. The nano-size lead-free piezoceramic powder can have a basic component of (K_xNa_1-x)NbO₃, where x ranges from 0 to 1. A weight ratio of a milling ball to a raw powder can be set, and then the milling ball and the raw powder can be provided into a milling container at the set ratio. Nano-size lead-free piezoceramic powder can be mechanochemically synthesized using a high-energy ball mill device.
