  • The process described is seen to consist of preparing separate solutions of readily-soluble salts of zinc and barium together with a third salt, which will further the reaction and at the same time upon uniting the solutions produce by one set of combinations lithopone and a marketable byproduct. This process, moreover, insures the greatest purity of the substances produced and avoids the expense attendant upon more difficult methods in common use. Thisis particularly true with respect to the manufacture of various grades of lithopone, since by properly calculating the amounts of the ingredients used, as above illustrated, any desired quality of lithopone may be produced without mixing additional substances to increase or decrease the percentage of zinc sulfid. The entire product, too, is an absolutely uniform mixture when prepared in accordance with my process.
  •  The invention relates to a production process of an inorganic pigment lithopone, in particular to a method for producing nanometer lithopone by using electrolytic zinc acid leaching residue. Background technique
  • 1. Quality Assurance
  • Following a request for assessment in 2020 by the EU, the European Food Safety Authority (EFSA) assessed E171, particularly for its genotoxicity. In 2022, the agency deemed the food additive no longer safe for use.  

  • A dense, white, opaque pigment composed of a mixture of Zinc sulfide (30%) and Barium sulfate (70%) with trace amounts of Zinc oxide. Lithopone, first produced in 1874, was called Orr's white. The mixture of the two components is so intimate that it is hard to distinguish microscopically. Lithopone is an inert, transparent pigment which is often used as a filler or as a base for lake pigments. Lithopone was widely used in house paints in the first half of the 20th century. It was also used for some artist grounds, inks and as a filler in Paper, Leather, and Linoleum. Now lithopone has mostly been replaced by Titanium dioxide.

  • The conventional surface treatment methods of titanium alloy include glow discharge plasma deposition, oxygen ion implantation, hydrogen peroxide treatment, thermal oxidation, sol-gel method, anodic oxidation, microarc oxidation, laser alloying, and pulsed laser deposition. These methods have different characteristics and are applied in different fields. Glow discharge plasma deposition can get a clean surface, and the thickness of the oxide film obtained is 2 nm to 150 nm [28]. The oxide film obtained from oxygen ion implantation is thicker, about several microns [914]. Hydrogen peroxide treatment of titanium alloy surface is a process of chemical dissolution and oxidation [1516]. The dense part of the oxide film is less than 5 nm [1721]. The oxide film generated from the thermal oxidation method has a porous structure, and its thickness is commonly about 10-20 μm [2225]. The oxide film from the sol-gel method is rich in Ti-OH, a composition that could induce apatite nucleation and improve the combining of implants and bone. It has a thickness of less than 10 μm [2628]. Applied with the anodic oxidation method, the surface can generate a porous oxide film of 10 μm to 20 μm thickness [2931]. Similarly, the oxide film generated from the microarc oxidation method is also porous and has a thickness of 10 μm to 20 μm [3233].

  • Peintures et revêtements : il convient pour une utilisation dans les mastics et dans les compositions des produits de jointoiement et d'étanchéité.
  • The R996 grade titanium dioxide from Lomon is particularly well-suited for use in the paint industry due to its superior tinting strength and dispersibility. These properties allow paint manufacturers to achieve vibrant and consistent colors in their products, resulting in high-quality finishes for a variety of applications.


  • There are many suppliers of barium sulfate in the market, each offering different prices and levels of quality. Some suppliers may offer lower prices, but their products may not meet the required specifications. On the other hand, some suppliers may offer higher prices but provide superior quality products. It is important to strike a balance between price and quality when choosing a supplier for barium sulfate.
  • Titanium dioxide rutile is a widely used white pigment in various industries, including paints, plastics, paper, and cosmetics. It is known for its excellent brightness, opacity, and UV resistance, making it a popular choice for a variety of applications.
  • In the paper industry, art painting supplies level, use as a white opaque pigment for a variety of printing paper filler, white pigment for pencils, watercolors, art painting.

  • Another crucial property of TiO2 is that it can show photocatalytic activity under UV light. This makes it effective for environmental purification, for different kinds of protective coatings, sterilisation and anti-fogging surfaces, and even in cancer therapy.

  • Moreover, Chinese manufacturers are acutely aware of the international demand for sustainable practices
  • Thirdly, titanium dioxide is a semiconductor material with a wide bandgap energy of 3
  • One of the key advantages of R1930 is its high refractive index, which allows it to scatter light more effectively, resulting in superior opacity and whiteness. This makes it an ideal choice for ink formulations that require high levels of coverage and brightness.
