Pintejin Ceramics is a professional ceramic manufacturer specializing in the production and manufacture of semiconductor ceramic parts. It is a professional ceramic manufacturer integrating calcination, molding, machining and inspection of semiconductor ceramic parts. Semiconductor ceramics are one of the key materials in the development trend of new technology, and the work of information content communication has become a focus. Undoubtedly, semiconductor ceramics have bright development prospects. The following is an introduction to the characteristics and development prospects of semiconductor ceramics by Pintejin Ceramics.
Alumina semiconductor ceramic parts The ceramic materials of semiconductor ceramics are mainly zirconia ceramics and alumina ceramics. The two ceramic materials have excellent characteristics such as high temperature resistance, wear resistance and corrosion resistance. They are widely used in industrial ceramic valves, ceramic plungers, ceramics Crucibles, ceramic bushings, injection-molded ceramic parts and other precision ceramic parts are widely used in military ceramics, textile ceramics, electronic and electrical ceramics, smart wearable ceramics, medical food ceramics, petrochemical ceramics and other industries. Therefore, semiconductor ceramics play their excellent functions in the development of industrial technology. 1. Characteristics of semiconductor ceramics: Taking barium titanate semiconductor ceramics as an example, when the temperature is below 100 °C, it exhibits ordinary semiconductor characteristics. That is, when the conductor temperature increases by a certain value from the beginning, the resistance decreases, which is a negative temperature coefficient. And when the temperature rises to a range above 100 °C. Its resistance rises sharply by several orders of magnitude with increasing temperature. It exhibits a strong positive temperature coefficient characteristic. The starting temperature of this positive temperature coefficient characteristic is called the Curie temperature, which is represented by tp, and the phenomenon of abnormal change in impedance is called the PTC characteristic. In the actual production process of PTC components, its Curie temperature can also be changed by the difference in production process and added materials.
Zirconia semiconductor ceramic parts 2. Development of semiconductor ceramics: Semiconductor ceramics are the key materials for sensitive components and sensor technology, and are a high-tech field that is rapidly developing in the world today. Related, its research and development and even production, involving physics, chemistry, materials science and engineering and other disciplines. Therefore, semiconductor ceramics are technology-intensive and knowledge-intensive industries. Japanese products have an absolute dominant position in the world market. The United States and Europe also account for a considerable amount. In contrast, China’s semiconductor ceramics started late, and there is still a significant gap between product performance and production level and the international advanced level. Since the reform and opening up, with the rapid development of the electronic industry, the requirements for semiconductor ceramics have become higher and higher. The development of semiconductor ceramics is facing many important problems to be solved urgently. This article discusses the current situation and development trend of semiconductor ceramics at home and abroad, and puts forward some superficial views for discussion, in order to promote the further development of my country’s semiconductor ceramics industry.
