耐高压介质陶瓷材料

Novel dielectric ceramics with high breakdown strength 

　　耐高压介质陶瓷材料在很高的电场强度下依然保持优异的绝缘特性和稳定的介电性能，根据其介电常数、耐电强度、力学强度、闪络强度等特性，分别用于高功率能量存储、能量传输、绝缘、支撑和封装等。在新一代高功率微波、高能粒子加速器、生物工程和医疗肿瘤治疗等高端技术领域有广泛需求。 

　　Novel dielectric ceramics with high breakdown strength still maintain excellent insulation properties and stable dielectric properties under high electric field. According to its dielectric constant, electrical strength, mechanical strength, flash strength and other characteristics, they are respectively used for high-power energy storage, energy transmission, insulation, support and packaging. It is widely needed in the new generation of high-power microwave, high-energy particle accelerator, bioengineering, medical tumor treatment and other high-end technology fields.
