Japan ceramics technology

The US car industry mainly applies autocatalysts on ceramic monoliths only GM uses pellets for 30% of its production. The two main manufacturers of ceramic monoliths are Coming, USA and NGK, Japan. The technology was developed by Coming in the early seventies.

We carry out scientific-technological work on two continents, namely the United States and Europe. Since we are in close contact to scientists of Japan in Asia, the thought arose to analyze and illustrate the field of glass-ceramics under the aspect af glass-ceramic technology worldwide.

Japan is the United States chief competitor in ceramics. There is a widespread but false perception that Japan leads the United States in ceramics in general. Nevertheless, it is clear that the Japanese effort in ceramics is comprehensive and long term and that several Japanese companies lead their U S. industrial counterparts in specific technologies. There is tremendous enthusiasm in Japan for the potential of ceramics, and a recent report of a U S. visiting team to Japan reached the following conclusions ...

By making use of the Internet I have searched all over the world for photographs of ceramic composite structures. In the end I received some from Mr K. Yoshida of the Research Laboratory for Nuclear Reactors, Tokyo Institute of Technology, Japan. These are photographs...

Magnetic ceramics are well established, but improvements and innovations continue to take place many new and exciting applications, theories and preparation technologies are currently under development. For instance, at the last scientific meeting devoted entirely to ferrites (held every four years), the 6th International Conference on Ferrites, Japan, October 1992, more than 550 research papers were presented by some 1159 authors.

During the last decade a significant effort was devoted to thin or low thickness (<10 pm) Pd-based membranes supported on different porous substrates and to move the technology from lab scale to larger surface dimensions. Among the few membranes provider/developers, three of them, ECN from The Netherland [16], a company from Japan and MRT from Canada [17] were selected and included in the project. A fourth company, Acktar from Israel [18] was also involved, but its membrane will be tested later. AU these membranes are Pd based, but with different supports. ECN membranes and those ones from Japanese manufacturer are made by a ceramic support whereas Acktar and MRT membranes have a stainless steel substrate. With the exception of ECN, all membranes are Pd/Ag alloy membranes. The membranes have a tubular geometry, with the exception of MRT which is planar.
