Titanium Dioxide (B101 Anatase) - China

Brief Overview
Titanium Dioxide, commonly known as Titania, is an inorganic compound recognized for its white powder form, denoted by the chemical formula TiO2. It primarily exists in two crystal structures, rutile and anatase. Anatase, prized for its cost-effectiveness, easy dispersion in water-based systems, and effective opacifying properties, exhibits untreated titanium dioxide with a refractive index of 2.55. However, its usage is limited in exterior paint, excluding applications like highway paints.
Manufacturing Process
The sulfur process facilitates the production of titanium dioxide (TiO2) in anatase and rutile forms through specific steps: 1. Dissolving the raw material containing titanium dioxide in concentrated sulfuric acid. 2. Precipitating hydrous titanium dioxide from the acidic solution through dilution and boiling (hydrolysis). 3. Eliminating contaminants through leaching. 4. Increasing particle size via calcination at temperatures around 1,000°C. 5. Purifying and subsequently coating the pigment with organic and inorganic oxides.
