TiO2aa

TiO2aa is a designation that typically refers to a specific grade or form of titanium dioxide (TiO2). Titanium dioxide is a naturally occurring oxide of titanium, with the chemical formula TiO2. It is a white, powdery substance that is widely used as a pigment in a variety of applications due to its brightness, opacity, and UV-blocking properties.

The "aa" suffix likely denotes a particular characteristic or manufacturing process of this titanium dioxide. Without further context, it is difficult to ascertain the exact meaning of "aa." However, such designations are commonly used in the chemical industry to differentiate between different grades of a substance based on factors like particle size, surface treatment, purity, or intended use. For example, TiO2 grades are often specified for use in paints, plastics, paper, cosmetics, food products, and photocatalytic applications. The specific properties of a TiO2 grade, indicated by its designation, determine its suitability for these diverse uses. Different manufacturing methods, such as the sulfate process or the chloride process, can also lead to variations in the final product and thus different grade designations.
