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.

- Particle size = 0.3-0.5 micrometers
- Project Economics:
Lithopone is a white pigment (PW5) co-precipitated from solutions of zinc and barium salts according to the following reaction:
- In 2021, the EFSA published a new opinion, stating that while titanium dioxide is not considered a concern for reproduction, development, or immunotoxicity, there is a lack of data to fully exclude a potential genotoxic effect. As a result, the European Union decided to ban its use as a food additive from May 2022, highlighting the importance of continuous monitoring and updating of safety assessments.

titanium dioxide ph manufacturer. The company's team of experienced engineers and researchers work closely with customers to develop tailor-made solutions that meet their unique requirements and specifications.- Anatase, a versatile and essential material in the world of advanced materials, is finding its way into various applications due to its unique properties. This compound, with its titanium dioxide (TiO2) structure, has been a subject of interest for researchers and manufacturers alike, leading to the establishment of numerous factories worldwide that specialize in the production of anatase products.
Panzhihua Dongfang Titanium Industry Co., Ltd. Dongfang, a well-known brand of titanium dioxide, a famous brand in Sichuan, a high-tech enterprise, a large supplier of titanium dioxide and titanium sponge, and one of the largest/leading titanium raw material production bases in China.
Titanium dioxide comes in the form of a white powder and is sometimes used in cosmetics to adjust a color to a lighter shade. This is also why it can produce a white cast.
- Firstly, let's talk about the physical properties of titanium dioxide. It is a white powder that is insoluble in water and has a high refractive index, which makes it an excellent material for producing bright and opaque colors. Moreover, it is non-toxic, chemically stable, and resistant to discoloration from sunlight or heat. These characteristics make it ideal for use in various products where durability and safety are crucial factors.
- Cosmetic grade titanium dioxide is considered safe for use in cosmetics, as it is a non-toxic and non-irritating substance. It is often used to provide a smooth and even finish to cosmetics, as well as to protect the skin from the sun's harmful UV rays.

- In addition to environmental considerations, the presence of titanium dioxide in water also has implications in water treatment and purification. TiO2's photocatalytic properties make it a promising material for water purification, especially in removing organic pollutants and heavy metals. Researchers in China are actively studying the potential of TiO2-based photocatalysts for water remediation, contributing to the global efforts in clean water solutions.
- To address these challenges, researchers are exploring alternative production methods that are more energy-efficient and environmentally friendly. For example, the use of solar energy to power the oxidation of titanium ore has been proposed as a way to reduce the energy consumption of the sulfate process. Other approaches include the development of new catalysts that can replace sulfuric acid in the oxidation step, as well as the exploration of bio-based feedstocks for TiO2 production.
Lithopone is produced by coprecipitation of barium sulfate and zinc sulfide. Most commonly coprecipitation is effected by combining equimolar amounts of zinc sulfate and barium sulfide:
The RGB LED panel was made ad hoc, and configured for solar simulation white light (including the absorption spectra of the nanoparticles: 390–410). No heat was detected at the working distance. The retina of the albino male Wistar rats were not affected under these conditions, because the intensity and time of the applied irradiation was lower than the regular fluorescent lamp bulb in the room (216.65 W/m2) [34].
