lithopone: meaning, definition, pronunciation and examples

Its use has declined significantly since the mid-20th century, largely replaced by titanium dioxide due to the latter's superior opacity and brightness. It may still be used in some niche or cost-sensitive applications.

Lithopone itself is considered to have low toxicity, especially compared to older lead-based pigments. However, as with all fine powders, inhalation should be avoided, and safety data sheets for specific grades should be consulted.

The name is derived from Greek 'lithos' (stone) and a likely contraction of 'opone' (perhaps related to its opaque, stone-like properties or component words). It is a coined trademark that became a generic term.

It is highly unlikely you would need to, unless you are specifically discussing historical paint, industrial pigments, or material science. In general contexts, 'white pigment' or 'filler' would be more widely understood.

A white pigment composed of zinc sulfide, barium sulfate, and other minor components, used in paints and coatings.
