FACILITIES

Preparation of alloys & powders

We need to be able to prepare thermally stable materials as well as metastable materials in order to develop novel magnetic materials.We have not only conventional fusion facilities but also various facilities capable of low-temperature synthesis and rapid cooling synthesis.

Chemical synthesis

We are developing rare-earth alloy magnets, which are usually prepared by metallurgical approaches, by chemical approaches such as reduction diffusion method.Therefore, we have various facilities for chemical syntheses.

Powder metallurgy

Rare-earth magnetic materials are usually weak in oxygen, and slight exposure to oxygen significantly deteriorates their magnetic properties. In addition, metastable magnets are degraded by large thermal load. Therefore, we have facilities to produce sintered magnets without air-exposure and to sinter with low-thermal-load.

Heat treatments

Many of next generation magnets required nitriding treatments ,carbonizing treatments, and hot-deformation. These treatments need furnaces that accept ammonia, methane, and hydrogen gases.We have many kinds of particular furnaces.
