High-energy-density zirconium titanium and lead stannate antiferroelectric ceramic and preparation method thereof
The invention relates to a high-energy-density zirconium titanium and lead stannate antiferroelectric ceramic and a preparation method thereof. The formula of the antiferroelectric ceramic material is (Pb1-1.5xLax)(ZrySn1-y-zTiz)O3, wherein x is greater than or equal to 0.01 but less than or equal to 0.03, y is greater than or equal to 0.4 but less than or equal to 0.7 and z is greater than or equal to 0.06 but less than or equal to 0.09. Through a component adjusting and improving process, the obtained PLZST ceramic material obtained has a huge AFE-FE phase change electric field (E is greater than 7kV/mm) and a high energy density (1.3-2J/cm<3>), and in a certain temperature range (20-100 DEG C) and a certain frequency range (0.01-100HZ), the antiferroelectric phase of the ceramic stably exists, and the amplitude of variation of the energy density is within 15%, thereby having very important meaning for developing a high-voltage pulse power capacitor with high energy storage, particularly a stable energy storage characteristic in a variable temperature condition.
