Lithopone B301, Lithopone B311 powder, brilliant white pigment used in paints, inks, leather, paper, linoleum, and face powder. It was developed in the 1870s as a substitute or supplement for lead carbonate (white lead), to overcome its drawbacks of toxicity, poor weathering, and darkening in atmospheres that contain sulfur compounds. Lithopone B301, Lithopone B311 powder is an insoluble mixture of barium sulfate and zinc sulfide that precipitates upon mixing solutions of barium sulfide and zinc sulfate. The precipitate is recovered by filtration, then calcined (roasted) at temperatures above 600° C (1,112° F). Although Lithopone B301, Lithopone B311 powder has been replaced in many applications by titanium dioxide, it is still widely used in a number of products, such as water paints.

One of the key features of pigment lithopone is its high pigment content, which allows for a more efficient use of the compound in a wide range of applications. This makes it a cost-effective option for manufacturers looking to achieve the desired color and opacity in their products. Additionally, the chemical composition of lithopone pigment makes it resistant to fading and discoloration, ensuring that the products maintain their appearance over time.

Inductively coupled plasma-optical emission spectrometry (ICP-OES) is another popular method for determining barium in TiO2. This technique uses an inductively coupled plasma to ionize the sample and then measures the intensity of light emitted by the resulting ions. ICP-OES offers high sensitivity and wide dynamic range, allowing for the detection of trace amounts of barium. It also requires specialized equipment, but its automation capabilities can reduce costs and improve efficiency.
