Improved oxidation process for the production of pigmentary white metal oxides |
| abstract |
There are various methods for the production of white metal oxides such as titanium dioxide in which one or more gas or vapor are heated by passage through an electric arc or electric discharge device. The electrodes have been found to introduce significant impurities into the final product. It has now been found, however, that the discoloring impurities can be very substantially reduced by having at least one of the electrodes and preferably all of the electrodes constructed from a metal such as aluminum, titanium, zirconium, or the alloys thereof or from the electrically conducting nitrides or carbides thereof. Since the impurity results from the oxidation of the electrode, it is essential that the oxides be essentially white or colorless. |
