High-temperature low-loss barium strontium titanate-based energy-storage ceramic and preparation method thereof
The invention discloses a high-temperature low-loss barium strontium titanate-based energy-storage ceramic which is represented by a formula BaxSr(1-x)TiO(3+y) clinker, wherein x represents mole fraction of elements of Ba and is greater than or equal to 0 but less than or equal to 0.5; y represents mass percent of a clinker by BaxSr(1-x)TiO3 and is greater than 0 but less than or equal to 15%; the clinker comprises the following components in percentage by weight: 30-50% of B2O3, 15-30% of SiO2, 15-30% of Bi2O3, 0-10% of Al2O3, 0-10% of ZrO2, 0-10% of BaO and 0-15% of CaO. In addition, the invention further discloses a preparation method of the high-temperature low-loss barium strontium titanate-based energy-storage ceramic. The high-temperature low-loss barium strontium titanate-based energy-storage ceramic disclosed by the invention is not only sintered at low temperatures to remarkably improve the compression strength of the energy-storage ceramic, but also the dielectric loss of the ceramic under a high-temperature condition is remarkably reduced, so that application of the barium strontium titanate-based energy-storage ceramic serving in the field of a solid energy-storage medium material under extreme conditions of high temperatures and high pressures is greatly expanded, thereby facilitating application and development of a high energy-storage density ceramic technology.
