Analysis of the present situation and development trend of the world's industrial ceramics

Since the emergence of precision industrial ceramics in the 1980s, the mechanical properties of industrial ceramics have been greatly improved, so that industrial ceramics materials penetrate into every corner of the world, from the toilet of the toilet to the heat shield of the spaceship cockpit can be seen in its traces. With the development of nano technology in recent years, the industrial ceramics industry has also developed another new technology era, and entered the situation of "nano ceramics" at the same time. IT is estimated that it can play a big role in the energy, medical, IT and other industries. Nanomization makes the strength, toughness and superplasticity of ceramic materials greatly improved, increase the overall strength of the material, more with anti-fouling, anti-wetting, scratch resistance, wear resistance, fire prevention, heat insulation and other functions, greatly improve the application range and efficiency of industrial ceramics.

Japanese ceramics towards high technology

Japan's industrial ceramics industry is very prosperous, accounting for 50% of all traditional industries in Japan: compared to Taiwan, the proportion of industrial ceramics employed in Japan is quite high. On the whole, the future trend of the Japanese industrial ceramic industry, in addition to the exquisite practical design, and quite high level, can be seen in the depth of Japanese ceramic design.

In addition, Japan also regards industrial ceramics as a high-tech industry that determines the future competitiveness, and spare no effort to invest a lot of money. The advanced industrial ceramics originals produced have occupied the main share of the international market. In the 1990s, Japan first proposed a functional material called gradient material, which provided another way for the composite of new ceramic materials. On this basis, the pore size distribution is graded, and the ceramic membrane materials with excellent performance can be prepared. The continuous innovation of high-tech ceramic materials and applications enables Japan to develop a broader development prospect in the chemical industry, petrochemical industry, food engineering, environmental engineering, electronics industry.

American ceramics are commonly used in the precision technology industry

In 2007, Freedonia Group published a forecast report on the demand of industrial ceramics market in the United States. In the report, it analyzed in detail that the demand for industrial ceramics in the United States will grow at an annual rate of 7% until 2010, in which electronic ceramic components are still the mainstream market. From 2010 to 2015, the production of alumina, titanium oxide, zirconia, silicon carbide, silicon nitride and other coatings and composite products will be applied in the fields of electronic devices, industrial machinery, chemical industry, environmental pollution prevention and control. In order to improve the efficiency of ceramic post-processing, developing towards the direction of saving energy, reducing environmental pollution and improving efficiency, the new technology and equipment of microwave sintering, continuous sintering or rapid sintering came into being.

Since 2000, the American Advanced Ceramics Association and the U.S. Department of Energy have jointly funded the 20-year American Advanced Ceramics Development Program, which focuses on basic research, application development, and product use of advanced ceramics to promote the application development of advanced structural ceramic materials. The goal is that by 2020, advanced ceramics, with their superior high temperature resistance, reliability and other unique properties, will become the first choice of economical and applicable materials, and be widely used in industrial manufacturing, energy, aerospace, transportation, military and consumer goods manufacturing. For example, the United States Grumman Corporation is currently studying the atmospheric supersonic aircraft engine ceramic material import, nozzle and nozzle components; DuPont has also developed ceramic matrix composite engine components that can withstand 1200℃-1300℃ and have a service life of 2000h; In Taiwan, Hesheng has made great progress in the research and development of anti-projectile ceramics in recent years.

European ceramics tend to be green and practical

European pottery industry is more practical, but also like painting, sculpture and architecture, it pays attention to the sculpture and decorative effect of works. Especially after the industrial revolution, the industry and economy of European countries have had a breakthrough development. The industrial production mode not only overcame the problem of manual production, but also promoted more diversified production methods. Especially in the design of Bauhaus in Germany, it emphasized the combination of art and industry, emphasized the simplicity and rationalization of the form, and paid attention to the utility and beauty, which made the European pottery take on a new look. At present, influenced by the simplicity of the late 1980s and 1990s, the works tend to be flexible and personal.

European countries are also investing a lot of money and manpower to develop functional ceramics and high-temperature structural ceramics. The current research focus is on the application of new material technologies in power generation equipment, such as ceramic piston covers, exhaust lining, turbocharged rotary and gas turbine. The cooling part is made of ceramic material, which can greatly reduce energy and heat loss; Ceramic heat exchangers have the ability to recover waste heat from boilers or other high temperature devices. Ceramic tubes can improve corrosion resistance and increase heat exchange efficiency, which plays an important role in energy saving in many industries.
