氧化钐一般指三氧化二钐，是一种无机金属氧化物，分子式是Sm2O3，可用于制备其他有机材料及催化剂等。 其为白色略带微黄的粉末，不溶于水，可溶于酸。

三氧化二釤 （化學式： Sm2O3），又稱 氧化釤 (III)，是 釤 的 氧化物。 它是在1879年由 保罗·埃米尔·勒科克·德布瓦博德兰 在 铌钇矿 （英语：Samarskite） 里发现的。

Sm2O3 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. The structure is three-dimensional. there are two inequivalent Sm3+ sites. In the first Sm3+ site, Sm3+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing SmO6 octahedra. The corner-sharing octahedral tilt angles are 57°.

2025年1月27日 · Samarium (III) oxide is used in optical and infrared absorbing glass to absorb infrared radiation. It finds use as a neutron absorber in nuclear power reactors to control the reaction. It is also used as a catalyst for the dehydration of primary alcohols to …

Sm2O3 crystallizes in the cubic Pn-3m space group. The structure is three-dimensional. Sm3+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Sm–O bond lengths are 2.36 Å. O2- is bonded to four equivalent Sm3+ atoms to form a mixture of corner and edge-sharing OSm4 tetrahedra.

2019年9月1日 · Sm 2 O 3 nanorods-based conductometric sensors were fabricated and tested for CO sensing at low concentration in air. The developed Sm 2 O 3-nanorods sensor presents high response, good selectivity and fast response to CO than previous rare-earth oxide sensors. The superior sensing performance is due to the nanorods morphology.

Samarium oxide nanoparticles, popularly known as SM-MITE powders, are available in coated and hydrophilic forms. They can be used as solid state electrolytes for sensors, capacitors and solid oxide fuel cells.

Samarium (III) oxide 99.9% trace metals basis; CAS Number: 12060-58-1; EC Number: 235-043-6; Synonyms: Samaria; Linear Formula: Sm2O3 at Sigma-Aldrich

Explore the - crystalline lattice structure of Sm2O3 rt with lattice parameters, 3d interactive image of unit cell, cif file, lattice constants & more.

2023年1月1日 · Here, we unveil the distribution, structure and elastic properties of Sm2 O 3 in a high-end Sm 2 Co 17 -type magnet. Results show that Sm 2 O 3 microparticles with size of 4.8 ± 2.1 μm randomly disperse in the magnet, and they serve as the preferential sites for segregation of micron-sized Zr-rich inclusions.
