Abstract

A dry silicated sodium zirconyl sulphate which does not gel on addition to water is prepared by reacting sodium zirconium silicate with sulphuric acid of at least 61 DEG B<\>e in a molar ratio of acid to silicate of from 1,5:1 to 2,5:1. The sodium zirconium silicate may be prepared by roasting finely-divided zircon with an approximately equimolar amount of sodium carbonate, for example, as soda ash. The silicated sodium zirconyl sulphate has a composition as follows:- .ZrO2.28%-31% (24%-30% in water-soluble ..form) .SiO2.13%-16% (1%-5% in water-soluble ..form) .SO3.34%-40% .Na2O.13%-16% .H2O.0,5%-4% The silicated sodium zirconyl sulphate may be employed for tanning (see Group VIII).
