rare-earth nucleusとは 意味・読み方・使い方

The hybrid cold storage material is obtained by providing a surface composed of a rare earth oxysulfide (e.g. gadolinium oxysulfide) as a nucleus with a layer (e.g. gadolinium-terbium-based oxysulfide) having a composition different from that of the nucleus.例文帳に追加

希土類オキシ硫化物（例えば、ガドリニウムオキシ硫化物）の核を造粒（例えば、転動造粒法）し、次いで、核と異なる組成を有する希土類オキシ硫化物（例えば、ガドリニウムオキシ硫化物とテルビウムオキシ硫化物の混合物）の粉体を、核の周囲に徐々に供給し、核の表面を、核と異なる組成を有する希土類オキシ硫化物層で被覆するよう造粒する。 - 特許庁

To provide a method for inexpensively manufacturing magnet powder having excellent magnetic characteristics at a yield enhanced by a reduction diffusion method by reducing the non-magnetic phase which lowers the magnetic characteristics of the rare-earth-iron-nitrogen-base magnet powder and reducing the distortion of the crystal which is the nucleus for magnetization inversion and the remaining of a-Fe.例文帳に追加

希土類—鉄—窒素系磁石粉末の磁気特性を低下させる非磁性相を低減させ、磁化反転の核になる結晶の歪みやα−Ｆｅの残留を低減させて、優れた磁気特性を有する磁石粉末を還元拡散法で収率を向上させ安価に製造する方法を提供。 - 特許庁

In the silicon nitride-based sintered compact, fine particles having diameters of ≤100 nm, which are composed of Mg or at least one rare earth element selected from La, Y, Gd and Yb and oxygen, and which are each composed of an amorphous nucleus part and an amorphous peripheral part, are contained in an amount of ≥5 pieces/μm^2 in silicon nitride particles.例文帳に追加

窒化ケイ素粒子内に、ＭｇあるいはＬａ，Ｙ，Ｇｄ及びＹｂからなる群から選ばれた少なくとも１種の希土類元素と、Ｏ元素とから構成され、核とその周辺部が非晶質相である粒径100nm以下の微細粒子が５個/μm^2以上存在する窒化ケイ素質焼結体である。 - 特許庁
