Titanium yellow, also nickel antimony titanium yellow, nickel antimony titanium yellow rutile, CI Pigment Yellow 53, or C.I. 77788, is a
yellow pigment with the chemical composition of
NiO·
Sb2O3·20
TiO2. It is a complex inorganic compound. Its melting point lies above 1000 °C, and has extremely low
solubility in water. While it contains antimony and nickel, their bioavailability is very low, so the pigment is relatively safe.
The pigment has
crystal lattice
In geometry and crystallography, a Bravais lattice, named after , is an infinite array of discrete points generated by a set of discrete translation operations described in three dimensional space by
: \mathbf = n_1 \mathbf_1 + n_2 \mathbf_2 + n ...
of
rutile, with 2–5% of titanium ions replaced with
nickel(II) and 9–12% of them replaced with
antimony(III).
Titanium yellow is manufactured by reacting fine powders of metal oxides, hydroxides, or carbonates in solid state in temperatures between 1000 and 1200 °C, either in batches or continuously in a pass-through
furnace.
Titanium yellow is used primarily as a pigment for
plastics and
ceramic glazes, and in art painting.
