What is Bismuth Vanadate (BiVO₄)? Bismuth Vanadate (BiVO₄) is a high-performance inorganic yellow pigment with strong tinting strength, excellent weather resistance and good photocatalytic activity under light. 2. Is BiVO₄ an environmental alternative to chrome yellow? Yes. BiVO₄ is chromium(VI)-free and cadmium-free, making it a safer and more environmentally friendly alternative to traditional chrome yellow pigments. 3. Where is BiVO₄ typically used? BiVO₄ is used in high-performance coatings, plastics, rubber compounds, ceramic materials, printing inks and other applications that require bright, durable yellow shades. 4. Does BiVO₄ have photocatalytic properties? Yes. Under appropriate light irradiation, BiVO₄ can generate reactive species that help decompose certain organic pollutants and odor-causing molecules on coated surfaces. 5. How does BiVO₄ perform outdoors? BiVO₄ offers excellent lightfastness and weather resistance, keeping color stable under sunlight, heat and moisture for long periods. 6. Why choose BiVO₄ from Kela Materials? Kela Materials provides BiVO₄ with consistent shade, controlled particle size and reliable quality, suitable for demanding industrial and environmental applications.
