Embodiment 1
[0022] First, weigh the BaTiO with an electronic balance 3 , Nb 2 o 5 , MnO 2 According to the molar ratio of 100:0.5:2, mix deionized water and zirconium balls with deionized water: zirconium balls: powder = 2:1:1, ball mill for 4 hours after mixing, pass through a 40-mesh sieve after drying, and then Add 7% paraffin by mass percentage, pass through an 80-mesh sub-sieve and granulate.
[0023] The granulated powder was pressed into a Ф10×1.1mm disc green body at 3MPa, and the green body was raised from room temperature to 550°C for debinding after 3.5 hours. At a flow rate of 50sccm N 2 In the air flow, the temperature was raised to 1000°C at 5°C / min, and then sintered at 1300°C at 2°C / min, and held for 3 hours to obtain a niobium-manganese-doped anti-reduction dielectric material with high insulation resistivity and low loss.
[0024] The upper and lower surfaces of the obtained product were evenly coated with silver paste, and the electrode was prepared by firing at 84...
