Titanium Dioxide
CAS Number: 13463-67-7
Molecular Formula: TiO2
Molecular Weight: 79.9
Titanium Dioxide
Titanium Dioxide USP Specifications
TiO2 --- 79.87 --- CAS 13463-67-7
Titanium Dioxide contains not less than 99.0 percent and not more than 100.5 percent of TiO2, calculated on the dried basis. If labeled as attenuation grade, then Titanium Dioxide contains not less than 99.0 percent and not more than 100.5 percent of TiO2, calculated on the ignited basis. Attenuation grade material may contain suitable coatings, stabilizers, and treatments to assist formulation.
Labeling: If intended for UV-attenuation, the material must be labeled as attenuation grade. If intended for UV-attenuation, and any added coatings, stabilizers, or treatments are used, the labeling shall include the name and amount of the additives.
Identification: To 500 mg add 5 mL of sulfuric acid, and heat gently. After fumes of sulfur trioxide appear, continue heating for a minimum of 10 seconds. Cool the suspension, and cautiously dilute with water to 100 mL. Filter, and to 5 mL of the clear filtrate add a few drops of hydrogen peroxide TS: a yellow-red to orange-red color develops immediately.
Loss on drying: Dry it at 105 for 3 hours: it loses not more than 0.5% of its weight.
Loss on ignition: Ignite 2 g, previously dried and accurately weighed, at 800 ± 25 to constant weight: it loses not more than 0.5% of its weight. If labeled as attenuation grade, ignite 4 g of titanium dioxide, accurately weighed, at 800 ± 25 to constant weight: it loses not more than 13% of its weight.
Water-soluble substances: 0.25%.
Acid-soluble substances: 0.5%.
Arsenic: The limit is 1 ppm.

DESCRIPTION
Titanium Dioxide occurs as a white, amorphous powder. It is prepared synthetically. It is insoluble in water, in hydrochloric acid, in dilute sulfuric acid, and in alcohol and other organic solvents. It dissolves slowly in hydrofluoric acid and in hot sulfuric acid.
Function: Color.
REQUIREMENTS
Identification: Add 5 mL of sulfuric acid to 500 mg of sample, heat gently until fumes of sulfur trioxide evolve, continue heating for at least 10 s, and cool. Cautiously dilute to about 100 mL with water, and filter. Add a few drops of hydrogen peroxide TS to 5 mL of the clear filtrate. A yellow-red to orange-red color appears immediately.
Assay: Not less than 99.0% and not more than 100.5% of TiO2, after drying and after correcting for any aluminum oxide and/or silicon dioxide found to be present in the sample.
Acid-Soluble Substances: Not more than 0.5%.
Aluminum Oxide and/or Silicon Dioxide: Not more than 2.0%, either singly or combined.
Antimony: Not more than 2 mg/kg.
Arsenic: Not more than 1 mg/kg.
Lead: Not more than 10 mg/kg.
Loss on Ignition: Not more than 0.5% after drying.
Mercury: Not more than 1 mg/kg.
Water-Soluble Substances: Not more than 0.3%.
