Title: Improvements in or relating to the manufacture of titanium oxide
IPC: C01G23/053
Filed: 1933-05-26
Abstract: Titanium oxide for use as a pigment is produced by slowly adding titanium tetrachloride to water, or preferably, hydrochloric acid, so that the titanium tetrachloride dehydrates the highly hydrated chloride first formed thereby producing a mixture of basic chlorides in the form of a dry, granular yellow powder, and heating this until a fluffy white powder is produced. The yellow powder corresponds to the formula Ti2(OH)3 Cl5.2H2O, or an equal mixture of mono- and dibasic chlorides.  It preferably contains one to two mols. water of hydration per mol. of monobasic chloride.  Heating is effected say at 100 to 300 DEG  C. or more, the particle size of the product decreasing with increasing temperature.  The fluffy powder may be lightly ground and suspended in water or other liquid.  Large particles are separated and further ground.  The remaining suspension is centrifuged or allowed to settle, and the product separated.  Fine particles remaining in suspension are dissolved in hydrochloric acid for re-use in the precipitation step.  A Dorr classifier or an air separation system may alternatively be used in the separation step. Colour additions may be admixed with the initial solution and precipitated with the basic chlorides.
