AI Technical Summary
Existing base metal ultra-high voltage multilayer ceramic capacitors are difficult to achieve ultra-high withstand voltage and excellent temperature stability under high dielectric thickness and high electric field strength, especially when the material properties degrade during sintering in a reducing atmosphere.
By combining BST matrix and NBT material, rare earth oxides are synthesized and doped through solid-state method to form a multiphase dielectric material structure. Combined with the sintering process of nickel and copper electrodes, base metal high-voltage multilayer ceramic capacitors are prepared.
It achieves high voltage resistance, stable dielectric temperature characteristics, low loss and long-term high-voltage reliability, and has excellent electrical performance and mechanical strength, making it suitable for high-voltage and high-temperature environments.
