Oxide sintering by air pressure control
Professor Hiromi Nakano of the Toyohashi University of Technology has collaborated with a company to develop a small, lightweight air-pressure control atmosphere furnace that can rapidly and uniformly synthesize periodical structures of Li2O-Nb2O5-TiO2 (LNT) solid solution materials at 3x ordinary pressure. The underlying mechanism was discovered using detailed composition/structure analysis. As the sintering process is reduced by one-fourth compared to conventional electric furnaces, this technology can also be applied to other materials.
The air-pressure control atmosphere furnace is a sintering furnace that uses a regular 100 V AC power outlet and saves up to 800 W of energy. With this furnace, pressurized gas is supplied/controlled using a compressor or gas flow and materials can be heated up to 1,100 degrees C. (FIG. 1)
