lithopone price suppliers

Having thus described the origin and uses of the pigment, we now come to the question, what is lithopone? It is, in short, a chemical compound usually consisting of 30.5 per cent zinc sulphide, 1.5 per cent zinc oxide and 68 per cent barium sulphate, but these proportions vary slightly in the different makes. Lithopone of this composition is sold as the highest grade, either as red seal or green seal, as it best suits the idea of the manufacturer. Many manufacturers, especially in Europe, sell and also export other brands under other seals, containing 24, 20, 18 and as little as 12 per cent of zinc sulphide with very small percentages of zinc oxide, the balance being usually barium sulphate, but sometimes certain portions of China clay or gypsum (calcium sulphate) or whiting (calcium carbonate). Such brands are not a chemical compound, but mechanical mixtures of the chemically compounded lithopone and the admixtures referred to.

The primary function of TiO2 in pigment production is its exceptional ability to provide brightness and opacity. When added to paints or coatings, it enhances their hiding power by reflecting light back to the observer's eye. This property not only improves the aesthetic appeal of the product but also reduces the amount of colorant needed, resulting in cost savings for manufacturers. Moreover, TiO2's high refractive index ensures that even small quantities can significantly impact the final appearance of the product.

The world of chemistry and materials science is a fascinating realm where innovation meets practicality. One such material that stands out for its versatility and widespread applications is titanium dioxide, commonly known as TiO2. This white pigment has been an industrial workhorse due to its exceptional properties such as high refractive index, UV protection, and excellent stability. However, the journey of a titanium dioxide manufacturer is not without challenges, especially in the pursuit of sustainable practices.
