Lanthanum and potassium codoping modified barium zirconate titanate based dielectric ceramic material and a preparation method thereof
The invention discloses a lanthanum and potassium codoping modified barium zirconate titanate based dielectric ceramic material and a preparation method thereof, and belongs to the technical field of synthesis of functional ceramics. The key points of the technical scheme are as below: the lanthanum and potassium codoping modified barium zirconate titanate based dielectric ceramic material is a Ba1-x(La0.5K0.5)xZr0.15Ti0.85O3 system formed by codoping of La and K in BaZr0.15Ti0.85O3, wherein x satisfies the relation of 0.04<=x<=0.06. The invention also discloses the preparation method of the lanthanum and potassium codoping modified barium zirconate titanate based dielectric ceramic material. The material provided by the invention obviously improves the high pressure resistance and dielectric properties of the barium zirconate titanate dielectric ceramic, effectively increases the breakdown voltage and dielectric constant of the barium zirconate titanate based dielectric ceramic material, and largely reduces the dielectric loss of the barium zirconate titanate based dielectric ceramic material.
