• Effects of Short Term Exposure: May cause mechanical irritation.
• Effects of Long Term Exposure: Repeated or prolonged contact may cause skin sensitization. Repeated or prolonged inhalation may cause asthma.
• Uses: Cobalt Sulfideis used as a catalyst for hydrogenation or hydrodesulfurization reactions. Cobalt sulfide is found in nature as the mineral sycoporite. It is used as a catalysts for the industrial process called?hydrodesulfurization. It is used to purify the cobalt from its ore & in qualitative inorganic analysis. It is used as a electrode material for lithium sulfur batteries, thermal batteries & lithium ion secondary batteries.

Technology Process of Cobalt sulfide

There total 2 articles about Cobalt sulfide 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:

sodium sulfide (1313-82-2) + cobalt(II) nitrate → cobalt sulfide (1317-42-6) + Co(OH)S

Guidance literature:

alkaline medium; formation of dimeric aquo complex of Co(III); γ resonance spectra;

Reference yield:

{Co(OH)2(dmgH)2}(1-) + rongalite (149-44-0) → cobalt sulfide (1317-42-6) + Co(OH)S

Guidance literature:

alkaline medium; gamma resonance spectra;

upstream raw materials:

sodium sulfide

rongalite
