Surface Modification of Sol–Gel Synthesized Ba0.85Ca0.15Zr0.1Ti0.9O3 using Stearic Acid Additives
This study explores a novel approach to enhance the piezoelectric performance of lead‐free BCZT ceramics synthesized via the sol–gel method. By coating the BCZT powder with only a 0.69 nm stearic acid layer, the electromechanical response is significantly boosted up to 359 pC N−1, revealing promising implications for high‐performance sensor and ...
