Safty Information:
  • Pictogram(s): Flammable (pyrophoric) at room temperature in powder form; store under inert gas, petroleum, or other oxygen-free liquid. When heated to approximately 200C in hydrogen, barium reacts violently, forming BaH2. TLV: for all soluble barium compounds, 0.5 mg/m3 (as barium). 
  • Hazard Codes:Flammable (pyrophoric) at room temperature in powder form; store under inert gas, petroleum, or other oxygen-free liquid. When heated to approximately 200C in hydrogen, barium reacts violently, forming BaH2. TLV: for all soluble barium compounds, 0.5 mg/m3 (as barium).

Technology Process of Barium

There total 85 articles about Barium 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: 100.0%

Guidance literature:
from solid recrystd. BaN6; hydrolysis; pure metal;

Reference yield: 100.0%

Guidance literature:
byproducts: NH3; decompn. in vac.;
Guidance literature:
5h in vac. at 1300-1340 °C; Metal distilles off. Repeated distn. gives 99.5% purity;
upstream raw materials:

magnesium

aluminium

pyrographite

barium sulfide

Downstream raw materials:
