Sodium perferrate

Barium perferrate,2 BaFe04.H20, is obtained as a purple precipitate on addition of barium chloride to a solution of the calcium salt 3 or of barium chromate to a solution of sodium perferrate.4... 

Sodium per ferrate, Na2Fc04, may be prepared in an analogous manner to the potassium salt already described. It also results when ferric oxide is fused with sodium peroxide and the cooled mass treated with ice. Sodium perferrate then passes into solution.3...
