Development of pyroelectric ceramics for high-temperature applications

Ultrasonic Transducer Fabricated Using Lead-Free BFO-BTO+Mn Piezoelectric 1-3 Composite

“…Recently, lead-free piezoelectric materials with relatively good piezoelectric properties have attracted a great deal of attention owing to environmental conservation [5]. Therefore, the lead-free ceramics were used in various applications, such as ultrasonic transducers [6][7][8][9], pyroelectric sensors [10] and actuators [11,12]. BFO-BTO system is proposed to be an important family of high-performance lead-free piezoelectric ceramics because of its good ferroelectric properties [13][14][15][16][17].…”

Ba-addition induced enhanced surface reducibility of SrTiO3: implications on catalytic aspects

“…[18][19][20][21] Oxygen vacancies in the structure play an important role in reactions involving dissociative O 2 activation 11,22,23 over oxide supports. [24][25][26][27][28][29][30] Several methods have been employed for the synthesis of these perovskite materials, such as sol-gel method, 31,32 solidstate reaction, 33 wet-chemical method, 34 combustion, 35 hydrothermal method, 36 etc. Among these, the hydrothermal method stands out due to its low-temperature requirements and lower cost of operation.…”
