かま軸メタル下の英語

この強磁性鉄合金粉末は，鉄を主成分とし且つ平均長軸長が２０ｎｍ以上で８０ｎｍ以下の針状の粒子からなるメタル粉を実質上酸素が存在しない条件下純水と反応させて粒子表面に金属酸化膜を形成し，必要に応じて弱酸化性ガスと湿式または乾式で反応させることによって得られる。例文帳に追加

The ferromagnetic iron alloy powder is obtained by reacting the metal powder consisting of the acicular particles essentially consisting of the iron and having the mean major axis diameter of ≥20 to ≤80 nm with pure water under conditions under which oxygen does not substantially exist to form metal oxide films on the particle surfaces and reacting the metal powder with a weak oxidizing gas by a wet or dry process when needed. - 特許庁
