Technology Process of SAMARIUM TELLURIDE

There total 8 articles about SAMARIUM TELLURIDE 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: 5.0%

samarium (7440-19-9) + tellurium (14683-12-6) → SmTe1.80 (12040-00-5)

Guidance literature:

With KBr; In melt; Sm, Te and KBr flux were mixed in fused-silica tube in Ar-filled dry box; evacuated; sealed; heated to 1223 K over 72 h; kept at 1223 K for 4 d;cooled at 2.5 K/h to 973 K; washed (H2O); dried with acetone;

DOI:10.1016/j.jssc.2006.07.010

Reference yield:

samarium (7440-19-9) + tellurium (14683-12-6) → samarium telluride (12187-02-9,12040-00-5)

Guidance literature:

In neat (no solvent); in vac. at 900°C;

DOI:10.1016/0038-1098(84)90664-1

Reference yield:

tellurium (14683-12-6) + samarium(III) fluoride (13765-24-7) → samarium telluride (12187-02-9,12040-00-5)

Guidance literature:

With H₂; In neat (no solvent); react. of pure SmF3 with gaseous Te and H2 at 1100 °C for 5 h, Sm3Te4, contaminated with small amounts of (SmO)2Te, was outgassed in a high vacuum at 1450 °C and Sm3Te4 decomposes to yield SmTe and Te;; (SmO)2Te impurity remained unchanged; final purification by sublimation in two steps at 1550 °C; X-ray powder diffraction;;

upstream raw materials:
