Piezoelectric ceramics is a class of electronic ceramic materials with piezoelectric properties. The main difference from typical piezoelectric quartz crystals that do not contain ferroelectric components is that the crystal phases that make up the main component are ferroelectric crystal grains.

Piezoelectric ceramics and alumina ceramics are the most widely used, most versatile, and most productive ceramic materials for oxide ceramics. click here to know more
In the electronics industry, it is possible to use electrical and magnetic ceramics called electronic ceramics. Electronic ceramics finally obtain ceramics with new functions through the precise control of surfaces, grain boundaries, and dimensional structures. It can be widely used in energy, home appliances, automobiles and so on.
Piezoelectric ceramics Sintering is a process in the production of alumina ceramics. Before sintering, many things change during sintering and after sintering:
1. Pre-sintering: In this process, the manipulation of air temperature is very critical. As the temperature rises, the body shrinks. However, the density and intensity change are not large, and there is no change in the grain ratio on the microstructure. The stage blank is very easy to split, because the moisture and the binder are eliminated, so pay attention to the heating rate.
2. Incipient Sintering: When there is a small change in temperature, the volume is reduced, and the density is changed very dramatically. Although there is no significant change in the grain ratio in the microstructure, the interparticles are no longer in coarse contact. Also greatly reduced, at this stage the body occurs due to the sintering of the volume reduction, called easy to produce the body split and shape.
3. Late sintering: As the temperature rises, all changes are more in-depth than in the previous step. Alumina ceramics are almost no longer achievable after the changes in density and intensity have reached maximum, and the proportion of grains on the microstructure changes significantly. The smaller, and not connected to each other, constitutes isolated pores, and some of the pores remain in the grains. The grain growth that occurs in the late stage of sintering will cause adverse reactions. In order to eliminate adverse reactions, the common solution is to add additives to grow the grain.
The advantages of electronic ceramic alumina ceramics, why in so many pipelines many people choose wear-resistant ceramic pipe, alumina ceramic is actually because of its advantages, so there are so many people are willing to choose wear-resistant ceramic pipes and ordinary Compared to the pipe, the internality of the pipe is corundum ceramic, so its lifespan can be extended to the maximum during the process of use. It is generally ten or even dozens of times that of an ordinary steel pipe. Such an astonishing figure is heard by many people. There will be sighs, then will the cost of using this kind of pipeline be very low? Of course, because of its longer lifespan, we are able to achieve maximum savings in the economic costs we are most concerned about. Secondly, because it is inherently ceramic, it has the property of not being afraid of high temperature, which determines that we can have a certain degree of thermal stability in the process of its use, and therefore it is not too fussy about the working environment and the nature of the work. . Finally, this kind of wear-resistant ceramic pipe has an advantage in the place where it is welded. Compared to ordinary steel pipe, this kind of pipe can be more solid in welding, so it will be even longer in the service life, let alone worry about it. Any problem occurred during use.
Because of the advantages of ceramic wear-resistant pipes, many factories and companies will eventually favor this product. And after we use this kind of pipeline, we can achieve the greatest savings in the cost of project cost. Therefore, this is not difficult to explain whether the alumina ceramic pipe can withstand the test?
Alumina ceramics specializing in the production of wear-resistant ceramic pipe, alloy wear-resistant pipe, organic wear-resistant pipe, non-standard wear-resistant pipe fittings and other series of wear-resistant pipe fittings and wear-resistant pipe products, and has a pipeline engineering design, pipeline measurement, pipeline The installation capacity provides you with the piping and fittings that meet your actual needs for your choice. It also provides guidance on piping design and pipeline construction. It has extensive experience in the application of wear-resistant piping.
Piezoelectric igniter is a kind of manual ignition device which uses piezoelectric effect as the theoretical basis and piezoelectric ceramic as medium. Through the violent impact of two piezoelectric ceramics (at the press of a button), instantaneous high-voltage currents are generated and used in various gas appliances. to learn more
Piezoelectric effect Welcome to visit this article on He-Shuai Ltd Piezoelectric effect: When some dielectrics are deformed by external forces in a certain direction, polarization occurs inside them, and positive and negative opposite charges appear on the two opposite surfaces. When the external force is removed, it will return to the uncharged state. This phenomenon…
