specific Embodiment approach

[0061] The piezoelectric ceramic material formulation involved in the present invention consists of core components and additional components, wherein the core components include, Pb 3 o 4 , SrCO 3 , Sb 2 o 3 , Nb 2 o 5 , Ni 2 o 3 , Fe 2 o 3 ,TiO 2 , ZrO 2 ; in the core component, and add the following additional component, SiO 2 , CeO 2 , the content of the additional components is added based on the total amount of the core components. The sum of the proportions of each component of the core component is 100%; based on the sum of the weight of the core components, a certain proportion of additional components are added, and the proportion of the added components is calculated based on the sum of the weight of the core components.

[0062] Among them, the core component (total ratio): Pb 3 o 4 : 65.07%-67.73%, SrCO 3 : 2.213%-2.3%, Sb 2 o 3 : 0.291%-0.303%, Nb 2 o 5 : 1.328%-1.382%, Ni 2 o 3 : 0.165%-0.172%, Fe 2 o 3 : 0.08%-0.083%, TiO 2 : 11.51%-11...
