- Lithopone, a crucial ingredient in the world of pigments and coatings, is a blend of zinc sulfide and barium sulfate. It's widely used in various industries due to its exceptional properties, such as high opacity, good whiteness, and heat resistance. Two popular grades of Lithopone are B301 and B311, both with a concentration of 28-30%. This article delves into the significance of these grades and the key suppliers in the market.
The global Lithopone market was valued at $169.8 million in 2019, and is projected to reach $218.6 million by 2027, growing at a CAGR of 3.30% from 2020 to 2027.

- In conclusion, titanium dioxide's in oil factories is a testament to its versatility and utility in the industrial domain. From improving the performance of drilling fluids to enhancing the durability of refinery coatings, TiO2 is a critical component in the oil industry's pursuit of efficiency, safety, and sustainability. As technology advances, the potential applications of this remarkable compound are likely to expand even further, solidifying its position as an indispensable element in oil manufacturing processes.
- Moreover, the commitment to sustainability is increasingly becoming a cornerstone for 1317-80-2% manufacturers
Titanium dioxide mainly comes from the earth’s crust, where it’s actually the ninth most common element. When processed, it becomes a fine powder with a vibrant white pigment.
EFSA's evaluation is related to the risks of TiO2 used as a food additive, not to other uses.
A safety review conducted by the EFSA in 2021 assessed thousands of studies published on titanium dioxide.
Le lithopone est produit par coprécipitation de sulfure de baryum et de sulfate de zinc, le plus souvent en proportions équimolaires, puis grillage de la pulpe résultante4.
This route affords a product that is 29.4 wt % ZnS and 70.6 wt % BaSO4. Variations exist, for example, more ZnS-rich materials are produced when zinc chloride is added to the mixture of zinc sulfate and barium sulfide.[1]

In a 2016 study published in Scientifica (Cairo), Egyptian researchers examined the effects of titanium dioxide nanoparticles on the organs of mice by orally administering the food additive daily, for five days. The results showed that the exposure produced “mild to moderate changes in the cytoarchitecture of brain tissue in a time dependent manner.” Furthermore, “Comet assay revealed the apoptotic DNA fragmentation, while PCR-SSCP pattern and direct sequencing showed point mutation of Presenilin 1 gene at exon 5, gene linked to inherited forms of Alzheimer’s disease.” The researchers wrote: “From these findings, “the present study concluded that TiO2NPs is genotoxic and mutagenic to brain tissue which in turn might lead to Alzheimer’s disease incidence.”
Lithopone has therefore traditionally been used in stoppers and putties, jointing compounds and sealing compounds, primers and undercoats and in road-marking paints.
Scrap zinc or concentrated zinc ores are dissolved in sulfuric acid, the solution is purified and the two solutions are reacted. A heavy mixed precipitate results that is 28 to 30% zinc sulfide and 72 to 70% barium sulfate.
Titanium Dioxide: E171 no longer considered safe when used as a food additive by European Food Safety Authority, May 6, 2021
Technical Specifications:(Standard:Q/SNBJ1-2012)
The major applications studied in the report include paints & coatings, plastics, printing inks, paper & pulps, rubber, leather, linoleum, and others. Region-wise, the market is studied across North America, Europe, Asia-Pacific, and LAMEA. Presently, Asia-Pacific accounts for the largest share of the market, followed by North America and Europe.
