Y2O3 is Corundum-like structured and crystallizes in the cubic Ia-3 space group. The structure is three-dimensional. there are two inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded to six equivalent O2- atoms to form a mixture of distorted edge and corner-sharing YO6 octahedra. The corner-sharing octahedra tilt angles range from 54 ...

Yttrium oxide (Y2O3): Does not have an individual approval but may be used under an appropriate group standard

2024年11月11日 · Yttrium oxide (Y2O3) stands as a testament to the remarkable journey of materials science. Initially considered as a candidate material for insulator coatings, its applications have transcended boundaries, harnessing its extraordinary properties for …

2022年1月14日 · Y 2 O 3 dispersoids contributed to improved strength mainly through grain refinement. Aggregation of Y 2 O 3 particles with relatively large size along grain boundaries is a main limiting factor for performance improvement in W–Y 2 O 3 alloys.

Yttrium oxide (Y2 O 3) is an excellent host for rare-earth dopant ions because of its excellent luminescence characteristics such as luminescence efficiency, color purity, and chemical and thermal stabilities.

Y2O3 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are six inequivalent Y3+ sites. In the first Y3+ site, Y3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Y–O …

As a trivalent transition metal, yttrium forms various inorganic compounds, generally in the oxidation state of +3, by giving up all three of its valence electrons. A good example is yttrium (III) oxide (Y2O3 Y 2 O 3), also known as yttria, a six-coordinate white solid.

Y2O3 crystallizes in the tetragonal P-4m2 space group. The structure is three-dimensional. Y3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are four shorter (2.24 Å) and two longer (2.49 Å) Y–O bond lengths. There are three inequivalent O2- sites.

1998年1月1日 · Yttrium sesquioxide (yttria) is a body-centered cubic material with bixbyite or cubic-C structure. Yttrium ions occupy two different sites: eight octahedral sites with C 3i point symmetry and 24 prismatic sites with C 2 symmetry. Six oxygen ions surround each yttrium ion.
