Ceramic products are becoming increasingly diverse, and the ceramic flute has gained popularity among young people.
The research and production of special ceramics in our country have made significant progress in the past 20 years, but in terms of practical application, production level, and degree of industrialization, we are still far behind developed countries. At the International High-Tech Ceramic Expo in Jingdezhen, experts predict that by 2010 and 2015, the output value of special ceramics in our country will reach 30 billion and 45 billion yuan, respectively, with huge market demand.
Our country has abundant special ceramic resources and strong research capabilities. As of 2002, more than 300 universities, research institutes, and production enterprises in our country are engaged in the development and research of special ceramics, with 63.6% of units focusing on functional ceramics and 36.4% on structural ceramics. Institutions such as the Chinese Academy of Sciences, Shanghai Institute of Ceramics, and Tsinghua University have played an important role in promoting the research of special materials in our country.
Special ceramics are widely used in fields such as industrial machinery and equipment, gas appliance industry, automotive (motorcycle) industry, textile industry, electromechanical industry, and medical devices. With economic development, the application range of high-tech ceramics continues to expand. Li Yunfei, deputy secretary-general of the Crystal Materials Committee of the Chinese Society of Silicate, said: "The demand for new materials in various industries in our country has promoted the development of the special ceramics industry, and the increased market demand has further promoted the development of the special ceramics industry." It is understood that special ceramics can be used in aerospace technology ('up to the sky') and in industries such as automobiles ('down to the ground'). Currently, special ceramics include nano-ceramics for the electronics industry, ablation materials for spacecraft, gas-sensitive ceramics for gas leak detection, bioceramics compatible with the human body, and transparent ceramics for optical materials. Li Yunfei introduced that the automotive parts industry has become an important application field for special ceramics, with catalytic converters for controlling exhaust emissions made from special ceramics, and the market for replacing catalytic converters alone reaches 11 million units per year, with profits reaching 5.5 billion yuan per year.
Experts believe that although there are many advantages in the development of special ceramics in our country, there are still many problems.
First, special ceramic materials, especially structural ceramics, have significant technical issues, high costs, low reliability, and strong variability, leading to a relatively narrow application range; the industrialization of technological achievements needs to be strengthened, and the technology and equipment for large-scale production are relatively backward and urgently need transformation; investment in technological development is still insufficient.
Secondly, competition from developed countries and international trade frictions are also factors restricting the development of our special ceramics industry. Currently, the challenges faced by our special ceramics industry mainly come from market competition with special ceramics enterprises in developed countries. The United States and Japan have developed rapidly in the production of special ceramics. Japan is the largest producer of special ceramics in the world, dominating the global special ceramics market, especially in the electronic ceramics market. In 1995, Japan accounted for 60% of the global special ceramics market, which decreased slightly in 2000 but still accounted for 50%. The United States is the second-largest producer of special ceramics in the world, with an average annual investment of 1.2 billion US dollars in high-tech ceramics, leading the world in basic research and process technology. Western Europe has also developed high-tech ceramics relatively quickly, and new ceramic brake discs developed in Europe are now used in supercars and the Audi A8.
International trade frictions are also intensifying. Our ceramics are about to become the next target of anti-dumping measures after lighters and leather shoes. Currently, domestic ceramic enterprises are actively responding to the impending anti-dumping storm.
Dong Xianlin, director of the Shanghai Institute of Ceramics, Chinese Academy of Sciences, and the Functional Ceramics Engineering Research Center, proposed that in the development of advanced ceramics research and development, we should: leverage advantages and highlight key points. Advanced ceramic materials cover a wide range of material types and application areas, and we cannot cover everything; we must adhere to the principle of 'doing what we can and not doing what we cannot.' Based on existing advantages, we should concentrate our efforts to effectively combine international research frontiers with national major needs to seek long-term development. At the same time, we should establish a complete research and development system and leverage team efforts. Advanced ceramics often have clear application prospects and target products, so a complete R&D system should be established to ensure continuity in research, development, and application.

Special ceramics may become popular in the future ceramic market, achieving high-tech industry.
New ceramics, due to their different chemical composition, microstructure, and properties compared to ordinary ceramics, are referred to as new ceramics or special ceramics. The different chemical compositions and organizational structures of new ceramics determine their unique properties and functions, such as high strength, high hardness, high toughness, corrosion resistance, conductivity, insulation, magnetism, light transmission, semiconductivity, as well as piezoelectric, optoelectronic, electro-optic, acousto-optic, and magneto-optic properties. Due to their special performance, these ceramics can be used as engineering structural materials and functional materials in fields such as machinery, electronics, chemical engineering, metallurgy, energy, medicine, lasers, nuclear reactions, and aerospace. Some economically developed countries, especially Japan and the United States.
