Titanium dioxide powder synthesis

Today, gas-phase processing plays an important role in the commercial production of a number of ceramic powders. These include titanium dioxide, carbon black, zinc oxide, and silicon dioxide. The total annual output of these materials is on the order of 2 million tons. The physical processes involved in gas-phase synthesis are typical of those involved in solution-phase synthesis—chemical reaction kinetics, mass transfer, nucleation, coagulation, and condensation.
