Titanium yellow

Nickel antimony titanium yellow pigment From Wikipedia, the free encyclopedia

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).[citation needed]

Properties

Titanium yellow has a melting point above 1000 °C and extremely low solubility in water.[citation needed]

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]
