Bismuth vanadium tetraoxide

Bismuth vanadate is one of the new pigments to enter the pigment field. The pigment bismuth vanadate (BiVO4) as the basic composition of hair color, high color saturation of bright yellow with green hues, with 580 nm wavelength light reflectance and high chromium and cadmium yellow yellow, so don’t have to blend organic pigments, directly instead of chromium and cadmium yellow yellow, it’s fundamentally solves the mischief in the production and use of paint. Not only will people’s health be guaranteed, but the use of pigment will be further expanded. The pigment has good light resistance, acid resistance, alkali resistance, various solvents and sulfur dioxide, and its heat resistance reaches over 200 degrees.

Bismuth yellow |P.Y.184 features.
The combination of bismuth yellow and organic pigment can produce very bright luster with high tone and strong covering power.
Bismuth yellow paint can be used for high demand products such as automotive products, powder coatings and coil coatings. The price is relatively high, but it is economical to use.
Bismuth yellow 184 can meet the requirements of various plastic products, and is suitable for high grade coatings which require good weather resistance.
Bismuth yellow 184 has excellent dispersion properties, whether used in waterborne coatings, powder coatings, oil paints or inks, which can be well dispersed.
The solvent resistance of bismuth yellow 184, excellent acid and alkali resistance, and low exposure to light, is a high weathering pigment with excellent performance.
Bismuth is yellow 184 bright and bright yellow, and the bright color is close to the high performance yellow organic pigment;
Bismuth yellow 184 has low carbon environmental performance, and bismuth yellow is not leaded. It can be used to replace inorganic pigments such as cadmium yellow and chrome yellow, which are used in situations requiring lead-free products.

The application of bismuth vanadate.
Yellow traffic signs.
Applicable to paint, ink addition.
It can be used in automobile surface paint, rubber products and coloring of plastic products, etc.
Bismuth vanadate is widely used in food, toys and other fields because of its high environmental protection and non-toxic properties.
Bismuth vanadate has broad application prospects in the field of photocatalysis.
Future outlook
Inorganic bismuth pigments are the best yellow inorganic pigments because of their coloring power, strong hiding power, no harm to the human body and environment, and they are attracting more and more attention. Its development prospects are mainly focused on the following aspects:
One is to develop bismuth vanadate to improve the performance of bismuth vanadate.
The second is to add the remaining ingredients on the original basis to improve the existing varieties;
Third, bismuth resources are abundant in our country, and the high added value of bismuth pigments should accelerate its photocatalytic application and the development of other applications.
