Development Trends of Advanced Ceramic Materials

Release time：2024-09-11click：0

The domestic advanced ceramic system continues to expand, the preparation technology continues to enrich and advance, and the application fields have also expanded from a single military and aerospace promotion to environmental protection, new energy, electronic information, etc. In the extensive civilian market, ceramic materials are also developing from structural ceramics and functional ceramics to structure-function integration. In view of the current status of advanced ceramics in China, key research and development still need to be carried out from several aspects:

1. Basic theoretical research and structural design of ceramic technology need to match the development requirements for advanced ceramics in application fields, and be able to provide support for new systems, new products, new applications and batch transformation Technical support;

2. The research and industrialization of ceramic powder technology should break the current situation that high-end powders are still restricted by foreign countries and meet the basic needs of the development of ceramic materials;< /div>

3. Research on toughening technology is one of the keys to breaking through the application limitations of advanced ceramics. Strengthening and toughening technology will bring about earth-shaking changes in the application of advanced ceramics;< /div>

4. Reducing the production cost of advanced ceramics is another key factor to break through the application limitations of advanced ceramics, especially mass production preparation technology, precision manufacturing technology of production equipment, and precision ceramics The development of processing technology will determine the ability to reduce costs;

5. Injection molding, injection molding and solid moldless molding technologies will become the molding technologies with the greatest potential for mass application. Microwave sintering and discharge plasma sintering technologies will bring new benefits to ceramics. Material performance brings a qualitative leap;

Combining the requirements of the “Thirteenth Five-Year Plan” and the requirements of industrial development, energy storage ceramics as energy conversion carriers, filtering ceramics (membranes) that play an outstanding role in environmental protection and other functions ——Structural integrated ceramics, structural ceramics with excellent comprehensive properties represented by Si3N4, and photoelectric ceramics represented by AlON transparent ceramics will become the main force in application and research.

There are more than 300 units engaged in advanced ceramic research in my country, and their technological accumulation is increasingly abundant. For example, Sinoma Advanced Materials Co., Ltd., Shanghai Institute of Ceramics of the Chinese Academy of Sciences, Tsinghua University, etc. The units represented have played an important role in promoting the development of advanced ceramics in my country in terms of new system research, design and industrial transformation.

The development of today's advanced ceramic materials is no longer limited to traditional technology, but more combined with modern information, automation technology, and different materials to form new technological science (computing Material science, functional-structural integration, etc.), a new era of advanced ceramic development is coming.
