2. Production technology of titanium dioxide and titanium dioxide.

摘要

The invention refers to a process for the production of titanium dioxide, containing 99% sulfur oxide by weight.At least 98% of the anatomical enzymesA main crystal is at least 200 nanometers in size.A crystal with a volume of less than 10% is less than 100 nanometers.Comments more than a month ago- Algali's 1200-2400 ppm (on the amount of sulphur and oxygen);1. The content is at least 1 ppm and not more than 1000 ppm (expressed in terms of the amount of Ti2 and corresponding to it).Weight Ratio from Al2O3 to N2O5 in the Range of 0.17 to 0.74And at least 0.1% (by weight) and 0.3% (by weight) w (by sulphur fluoride and sulphur and oxygen content).And titanium dioxide obtained by this process.
