Title:
SINTERING DEVICE FOR USE IN PREPARATION OF LOW-TEMPERATURE SINTERED PIEZOELECTRIC CERAMICS
Document Type and Number:
WIPO Patent Application WO/2023/010769
Kind Code:
A1
Abstract:
Disclosed in the present invention is a sintering device for use in preparation of low-temperature sintered piezoelectric ceramics. The sintering device comprises a first power supply, a second power supply, a first mounting block and a second mounting block. The first mounting block is connected to the second mounting block by means of a lifting mechanism. The first mounting block and the second mounting block are respectively and correspondingly internally provided with a first sintering disc and a second sintering disc, wherein inner walls of the first sintering disc and the second sintering disc are respectively and correspondingly provided, in an arc shape along the inner walls, with a first placement groove and a second placement groove; two ends of the first placement groove and the second placement groove are respectively and correspondingly provided with first electrically conductive silica gel, and inner middle walls of the first placement groove and the second placement groove are respectively provided with chromium-nickel electrically conductive filaments; a plurality of chromium-nickel electrically conductive filaments are electrically connected by means of the first electrically conductive silica gel; and the chromium-nickel electrically conductive filaments are electrically connected to the first power supply. According to the present invention, electric fields are generated around the first sintering disc and the second sintering disc by means of the chromium-nickel electrically conductive filaments, such that the temperature and the time required for sintering are reduced under the effect of the electric fields, and thus the sintering device has good practicability.
