SINTERING DEVICE FOR PREPARING LOW-TEMPERATURE SINTERED PIEZOELECTRIC
CERAMICS LU501415
The present invention belongs to the technical field of sintering devices for piezoelectric ceramics materials, and particularly relates to a sintering device for preparing low-temperature sintered piezoelectric ceramics.
Piezoelectric ceramics are mainly used for manufacturing an ultrasonic transducer, an underwater acoustic transducer, an electroacoustic transducer, a ceramic filter, a ceramic transformer, a ceramic frequency discriminator, a high pressure generator, an infrared detector, a surface acoustic wave device, an electro-optical device, an ignition device and a piezoelectric gyroscope.
Piezoelectric ceramics are a kind of electronic ceramic materials with piezoelectric properties, which have the main differences from typical piezoelectric quartz crystals without ferroelectric components that: crystal phases of main components of the piezoelectric ceramics are all ferroelectric grains. As ceramics are polycrystalline aggregates with randomly oriented grains, spontaneous polarization vectors of all the ferroelectric grains are also randomly oriented.
In order that the ceramics can show macroscopic piezoelectric properties, it is necessary to place the piezoelectric ceramics in a strong DC electric field for polarization treatment after the piezoelectric ceramics are fired, and the end faces of the piezoelectric ceramics are coated with electrodes, so that the original spontaneous polarization vectors with chaotic orientations are preferentially oriented along the electric field direction. After polarization treatment, the piezoelectric ceramics retain the certain macroscopic residual polarization intensity after the electric field is cancelled, so that the ceramics have certain piezoelectric properties.
In the use process of the existing piezoelectric ceramics, due to the stress generated in the long-term use process, the piezoelectric ceramics are fatigued, and the Curie temperature of the piezoelectric ceramics is not high, thereby shortening the service life of the piezoelectric ceramics; and in addition, when the piezoelectric ceramics are sintered, the piezoelectric ceramics need to be sintered at high temperature for a long time, thereby reducing the processing efficiency of the piezoelectric ceramics and increasing the energy consumption of a sintering furnace.
