Product Introduction
Rare Earth Oxides
●Purity
There are various grades of product from 99.9% (3N) to 99.9999% (6N).
Please contact us for details.
●Particle size
We have a line-up from micron scale to nano scale.
For fine powders, we have the following line-up.

・The oxides of La and Nd have high moisture absorbency and it is difficult to make them into fine particles.
Instead of the above, we propose hydroxides.
・The △ means that there is no trial production so far.
・Sc is available in STD type of about 7-13 µm and fine powder type of about 0.5 µm.
