Short description: Nickel antimony titanium yellow pigment

Titanium yellow is a yellow pigment with the chemical composition NiO·Sb₂O₃·20TiO₂. It is considered a complex inorganic color pigment (CICP)^[1]^[2], formerly known as a mixed phase metal oxide^[2]. The pigment has a rutile crystal lattice^[1], with 2–5% of titanium ions replaced with nickel(II) and 9–12% of them replaced with antimony(III).

Properties

As other CICPs, it has excellent heat stability and good chemical stability.^[2]

Production

CICPs such as titanium yellow are manufactured by calcining fine powders of metal oxides, hydroxides, or carbonates in solid state at temperatures between 650 and 1300 °C.^[1]

Use

Titanium yellow is used primarily as a pigment for plastics^[3] and ceramic glazes^[2], and in art painting.

It also finds use in high-end applications such as automotive and coil coatings.^[2]

Safety

While titanium yellow contains antimony and nickel, it is considered relatively inert and can be regarded as "physiologically and environmentally harmless."^[2]
