titanium dioxide producers manufacturers

Lithopone or sulphide of zinc white has been in general use for twenty years or more in many industries where a white pigment of considerable body or hiding power is required that is not subject to change like lead carbonate and has not the brittle character of zinc oxide, besides being sold at a lower figure than either of these. Nevertheless it is still comparatively new to the general painting trade. Because of our tariff protection its manufacture in this country has made great progress. Yet in spite of this and the duty imposed on it, the imports are still in excess of the quantity manufactured here. A short history of its origin will no doubt prove of interest to our readers.

After settling, the clear solution containing the titanium oxide, is run oil andfurther processed, whereby a roduct is obtained containing approximate y 35 per cent titanium oxide, 2 per cent sulphuric acid and 63 per cent of water. This product is known in the trade as titanium acid cake. It is a plastic mags having somewhat the consistency of mu 1 ljha've discovered that lithopone can be greatly improved by the suitable use of this titanium acid cake, and that the results obtained are dependent to a large extent upon the methods'by which this titanium acid cake is used,'in the production of lithopone.
