Estimating the term…
This invention relates to the method for preparing oxygen compounds of antimony with metals. According to the invention, the method for preparing oxygen compounds of antimony with metals consists in oxidation of antimony trioxide by hydrogen peroxide at a temperature from 40.degree. to 100.degree.C to form a suspension of hydrated antimony pentoxide and interaction of the obtained suspension of hydrated antimony pentoxide with metal compounds with subsequent drying ad calcining at temperatures from 300.degree. to 700.degree.C. The invention can be employed in the manufacture of metal oxide-antimony catalysts and metal-oxide resistor materials.
A method for preparing oxygen compounds of antimony comprising in combination (a) oxidizing antimony trioxide with hydrogen peroxide in a quantity not less than stoichiometric in an aqueous medium at a temperature of from 40.degree. to 100.degree. C to form a suspension of hydrated antimony pentoxide, (b) maintaining said suspension of hydrated pentoxide at said temperature, (c) reacting said suspension with at least one of the salt, hydroxide or oxide of an element selected from the group consisting of group Ce, Te, P, B and metallic elements of IB, IIA, IIB, IIIA, IIIB, IVA, IVB, VA, VB, VIB, VIIB and VIII of the Periodic Table, (d) drying and then (e) calcining the resulting material to form the desired compound.
