Subsequently, barium sulfate, another crucial ingredient, is derived from barite, a naturally occurring mineral rich in barium. The barium sulfate is then mixed with the synthesized zinc sulfide in precise proportions to create the desired lithopone pigment. The mixture undergoes a series of processes, including grinding and classification, to achieve the required particle size distribution and enhance its performance characteristics.

Titanium dioxide (TiO2) is by far the most suited white pigment to obtain whiteness and hiding power in coatings, inks and plastics. This is because it has an extremely high refractive index and it does not absorb visible light. TiO2 is also readily available as particles with the right size (d ≈ 280 nm) and the right shape (more or less spherical) as well as with a variety of post-treatments.

However, the pigment is expensive, especially when the volume prices of systems are used. And, there always remains a need to develop a full-proof strategy to obtain the best results in terms of cost/performance ratio, scattering efficiency, dispersion… while using it in coating formulations. Are you searching for the same?

Explore the detailed knowledge of TiO2 pigment, its scattering efficiency, optimization, selection, etc. to achieve the best possible white color strength and hiding power in your formulations.

    3. To give you an idea of how unreliable iron is, Bronze Age civilizations actually knew about iron. Iron is actually the fourth most abundant element in the Earth’s crust. It was just that iron was so prone to breaking that Bronze Age civilizations preferred bronze, an alloy of copper and tin, two much less common elements. The ancient Greeks would sail to Britain—literally going to England in a rowboat—to get the tin.
