The Measurement of Sodium Hexafluoroantimonate′s Solubility and Study on Influence Factor;

Removal of arsenic and antimony from oxidated solution of sodium thioantimonite production by air oxidation;

Study on preparation process of sodium sulfantimonate by sodium antimonate;

The synthesis of sodium antimonate from antimony concentrates by chloridizing leaching-oxidation and hydrolysis decomposition-alkali synthesis process is investigated.

The results that sodium pyroantimonate was prepared by air oxidation was introduced in this paper.

By using stibnite direct preparation of sodium pyroantimonate the new process were studied and satisafactory results were obtained.

The primary two methods to manufacture sodium pyroantimonite are Hydrogen peroxide oxo process and air oxo process,and the manufacturing costs of hydrogen peroxide oxo process is higher than that of air oxo process,but the latter should be deeply researched on decreasing the oxidizing time and r.
