Abstract
Sodium antimonate is made to react with an acid solution so as to transform a fraction of the sodium antimonate into pentavalent antimony oxide, thus producing a mixture of pentavalent antimony oxide and sodium antimonate, the so produced mixture is separated from the solution and that mixture is dried and pulverized. The so produced powder presents good flame retardant properties.
