titanium dioxide rutile tio2

Historically, the first mentions of zinc sulfide being utilized as a pigment were approximately sixty years before the everyday use of lithopone. Originally, it was thought to be appropriate for coloring rubber. In England, a patent was granted for this process. Two decades after this, the focus shifted to zinc sulfide as a suitable pigment for paint. The year 1874 witnessed the patenting of a manufacturing process for a novel white pigment composed of zinc sulfide and barium sulfate. Dubbed Charlton white or Orr’s white enamel, this began a new era for white pigments.

In the wholesale market, titanium dioxide is available in various forms, including anatase, rutile, and brookite. Each form offers distinct advantages depending on the specific application requirements. For instance, anatase titanium dioxide is known for its high photocatalytic activity, making it an ideal choice for environmental applications such as air purification and water treatment. Rutile, on the other hand, is characterized by its high refractive index and excellent weathering resistance, making it a preferred choice for automotive coatings and plastic additives.
