Technology Process of Ytterbium selenide

There total 3 articles about Ytterbium selenide which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield:

selenium (7782-49-2) + ytterbium → ytterbium selenide (12039-54-2)

Guidance literature:

20 h; 800°C;

Reference yield:

selenium (7782-49-2) + ytterbium selenide (12039-54-2) → α-Yb3Se4 (12039-54-2)

Guidance literature:

Reaction under near-equilibrium conditions in evacuated silica ampoule.;

DOI:10.1016/0925-8388(93)90581-7

Reference yield:

Yb2O2Se → ytterbium(III) oxide + selenium (7782-49-2) + selenium dimer (12185-17-0) + ytterbium selenide (12039-54-2) + ytterbium

Guidance literature:

In neat (no solvent); heating in the range 1753 1997 K in Knudsen cell; no isolation, investigation by Knudsen effusion method; X-ray diffraction of solid residue;
