摘要
We studied the influence of heat treatment time on the optical, thermal, electrical, and mechanical properties of stron- tium barium niobate （Srl-xBaxNb206; hereafter SBN） piezoelectric glass-ceramics with tungsten bronze-type structure, which have good piezoelectric properties and are important lead-free piezoelectric materials. We found that the best heat treatment time is 4 h. The properties of the prepared materials are better than that of SBN ceramics and the glass-ceramic growth is faster than the SBN crystal when the heat treatment time of the SBN piezoelectric glass-ceramic is controlled, reducing the preparation costs greatly.
