The dry particles are tested for BET surface area and that value is correlated back to an average particle size based on historical data and known relationships between these parameters. The particle size is not tested directly.

通常cerium oxide nanoparticlesの水分散液は透明な黄緑色ですが、御社の製品であるcerium (IV) oxide, dispersion (643009)は不透明な白濁液です。可視光を遮断する為に白濁させている様ですが、何か保護剤は添加されておりますでしょうか？
1 answer-
No protective agents are added to block visible light. The off-white appearance is simply due to the dispersion of the Cerium(IV) Oxide nanopowder in the water.
