titanium dioxide

This term refers to a specific chemical compound used primarily for its physical properties of brightness and opacity. In industrial contexts, it is often referred to as "white pigment" or "TiO2" in technical documentation. It is characterized by its ability to scatter light, making it indispensable for creating a solid, non-transparent finish in coatings.

As a chemical substance, it is treated as a mass noun. It does not have a plural form in standard usage, as it refers to the material itself rather than individual units of the compound.
