Titanium Nickel Yellow Inorganic Enamel Pigment
Titanium nickel yellow is an excellent non-toxic and environmentally friendly inorganic pigment. The advantages are good dispersion, high hiding power, excellent light resistance, weather resistance and heat stability, acid and alkali resistance and chemical corrosion resistance, no bleeding and migration. , suitable for environmentally friendly products, and can also be used as enamel pigments.
Titanium nickel yellow pigment is usually expressed as TiO2-NiO-Sb2O3. This crystalline pigment is a solid solution composed of three oxides of titanium oxide, nickel oxide and antimony trioxide. It is a new type of yellow pigment, which was only put on the American market in 1954. At that time, it was dubbed the sun yellow, and it was also called titanium nickel antimony yellow.
In general, heavy metals such as lead, chromium, arsenic, antimony, and cadmium are toxic. Titanium-nickel yellow pigment contains a considerable amount of antimony oxide, but because it has formed a eutectic eutectic with titanium oxide and nickel oxide , the chemical properties are very stable. It will not decompose antimony and nickel components under various conditions of use, so the titanium-nickel yellow pigment is non-toxic. The drug test of nickel yellow pigment on various animals also proved that it is non-toxic. Various natural exposure and artificial accelerated weathering tests have proved that the durability and weatherability of titanium nickel yellow are better than rutile titanium dioxide.
Titanium-nickel yellow is a solid solution. Nickel and antimony enter the crystal of titanium oxide by thermal diffusion at a high temperature of about 1000 °C, and the chemical properties are very stable. Boil Nitinol in hydrochloric acid and sulfuric acid, it will neither decompose nickel nor antimony. Excellent stability to oxidizing and reducing agents and sulfides.
