AI Technical Summary

Problems solved by technology

Commonly used piezoelectric ceramics are used in extrusion igniters. During each extrusion process, the number of electric sparks generated is small (the number of electric sparks is less than 5), and the electric sparks are weak (the discharge distance is less than 4 mm), which leads to extrusion ignition. The igniter is not effective in igniting the burning material

Abstract

The invention discloses piezoelectric ceramic for an extrusion type igniter and a preparation process of the piezoelectric ceramic, which are characterized in that the piezoelectric ceramic is a ceramic material formed by preparing X lead oxide, (1-X) barium carbonate, Y zirconium oxide and (1-Y) titanium dioxide added with 0-5 weight percent of antimony oxide and 0-1 weight percent of manganese oxide, wherein X and Y represent mole percent and respectively have a number range of 0-0.99. The invention has the beneficial effects that the performance is improved by aiming at the problem existing in the practical application of the piezoelectric ceramic through introducing oxide into a piezoelectric material prescription; the prepared piezoelectric ceramic is used for the extrusion type igniter and can generate a large quantity of electric sparks in each extrusion process; and the electric sparks have stronger energy, therefore, the piezoelectric ceramic has good popularization value.

Description

technical field [0001] The invention relates to the technical field of piezoelectric ceramics, in particular to a PZT piezoelectric ceramic and a preparation process thereof. Background technique [0002] Piezoelectric ceramics, a functional ceramic material capable of converting mechanical energy and electrical energy, belong to inorganic non-metallic materials. In terms of energy conversion, piezoelectric ceramic igniters can be manufactured by using the characteristics of piezoelectric ceramics to convert mechanical energy into electrical energy. The extrusion igniter is designed based on the principle of applying a certain degree of extrusion force to the piezoelectric ceramics, and the piezoelectric ceramics generate electric sparks to ignite the combustibles. Commonly used piezoelectric ceramics are used in extrusion igniters. During each extrusion process, the number of electric sparks generated is small (the number of electric sparks is less than 5), and the electri...
