Abstract

The invention discloses a piezoelectric ceramic with high performance for the atomization of electronic cigarette oil. The general chemical formula of lead zirconate titanate ternary material is Pb (1‑x‑y) Ba x Ca y [(Sn 1 / 3Nb 2 / 3 ) (1‑m‑n) Zr m Ti n ]O 3 ; Wherein said general chemical formula: x=O.O1~O.O7; y=O.O1~O.O7; m=O.4O~O.48; n=-O.45~O.49. The piezoelectric ceramic material of the invention has relatively high piezoelectric strain constant d33, electromechanical coupling coefficient kp, moderate mechanical quality factor and dielectric loss, and is a high-performance piezoelectric ceramic material.

Description

technical field [0001] The invention relates to the field of piezoelectric ceramics, in particular to a high-performance piezoelectric ceramic used for electronic cigarette oil atomization and a manufacturing method thereof. Background technique [0002] With the development of science and technology and the progress of society, people's understanding of health is also constantly improving. In this environment, electronic cigarettes have emerged as a substitute for cigarettes or cigarettes to satisfy the majority of smokers' dependence on cigarettes. , greatly reducing the health hazards to oneself and others. During the working process of ultrasonic atomizing electronic cigarette products, the piezoelectric ultrasonic atomizing sheet (referred to as atomizing sheet) is in a dry burning state, and the surface temperature of the atomizing sheet will reach 170°C instantaneously, which is different from the traditional ultrasonic atomization application technology. The big dif...
