Technology Process of discandium tritelluride

There total 10 articles about discandium tritelluride 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: 85.0%

Sc2Te + palladium (7440-05-3) → scandium telluride (12166-44-8) + Sc6PdTe2

Guidance literature:

In neat (no solvent, solid phase); pressed pellets of Sc2Te and Pd heated to 1050°C for 72 h;

DOI:10.1021/ja002875j

Reference yield: 80.0%

scandium + Sc2Te3 + nickel (7440-02-0) → scandium telluride (12166-44-8) + Sc5Ni2Te2

Guidance literature:

In neat (no solvent, solid phase); absence of air and moisture; molar ratio Sc:Ni:Te=3:1:1, welded Ta tube inside evacuated silica tube, 1000°C for 24 h, cooling to 700°C at 5°C/h, then to room temp.;

DOI:10.1021/ic981073a

Reference yield:

scandium + tellurium (14683-12-6) → scandium telluride (12166-44-8)
