Natural barite and anthracite containing more than 95% barium sulfate are mixed and fed at a ratio of 3:1 (mass). After being crushed to a diameter of less than 2cm, it enters the reduction furnace. The furnace temperature is controlled to be 1000-1200°C in the front section and 500-500 in the back section. 600°C, the reduction furnace rotates at a speed of 80 seconds per revolution, and the reaction conversion rate is 80% to 90%.
Apart from the cosmetics industry, the coatings and plastics industry is also expected to contribute significantly to the growth of titanium dioxide in 2023. Coatings made from titanium dioxide offer excellent hiding power, durability and weather resistance, making them ideal for outdoor applications. Demand for high-quality coatings is expected to surge as the construction and automotive industries expand. Titanium dioxide is at the forefront of providing aesthetic and protective coatings, making it an indispensable ingredient in the industry.
Lithopone can also be used as raw material of putty to fill gaps; Adding 20% lithopone to the concrete to make artificial quartz without harming its light resistance and solidification; It can improve the impact resistance and electrical performance when used in fire safety polyester chemicals; These are the raw materials of audio vinyl records used for turbojet engine dye and thermal insulation coating and insulating layer.
Chemical pigment manufacturers play a crucial role in the production of various products in industries such as cosmetics, paints, plastics, and textiles. These manufacturers are responsible for creating pigments that give color and appearance to different materials, making them more attractive and appealing to consumers. One of the key advantages of lithopone is its high opacity, which allows for a more efficient use of the pigment in paint and ink formulations. This, in turn, helps to reduce the overall cost of production for manufacturers. Additionally, lithopone is highly resistant to weathering and chemical exposure, making it a popular choice for outdoor applications.
In addition to its excellent color properties, R996 grade titanium dioxide also offers outstanding durability and weather resistance, making it an ideal choice for exterior paint applications
. The pigment's UV protection properties help to prevent color fading and degradation caused by exposure to sunlight and other environmental factors.Pigmentary TiO2 particles are approximately 200-350nm in dimension and this form accounts for 98 percent of total production. It is used mainly for light scattering and surface opacity applications. It is used as a base for various colour paints or as a standalone ‘brilliant’ white.
In general, nanoparticles have been shown to accumulate in the body, particularly in organs in the gastrointestinal tract, along with the liver, spleen, and capillaries of the lungs.
Titanium Dioxide: E171 no longer considered safe when used as a food additive by European Food Safety Authority, May 6, 2021

A 2012 study published in the journal Environmental Science & Technology noted that children are especially exposed to titanium dioxide because of the food that contains the food additive and is particularly marketed to children, including candy and cakes.
The journey of titanium dioxide begins with the mining of ilmenite, rutile, or anatase, which are the three main titanium ore minerals. These minerals are then transported to a titanium dioxide factory where they undergo a series of processing steps.
The company has a wide variety of products, mainly including rutile titanium dioxide R818, R838, R868, R878, covering profiles, also have anatase TiO2 A1. Soft plastics and masterbatches, flat coatings, high-gloss coatings, water-based coatings, oil-based coatings, rubber, powder coatings, papermaking and other special fields, its products have been known in the market for their excellent whiteness and brightness, good hiding power and tinting power, stable application performance, and stable product quality and supply capacity.
One of the key advantages of TiO2 R605 lies in its multi-purpose nature Lithopone 28-30%, also known as B301 and B311, is a white pigment that has been widely used in various industries due to its excellent properties such as high brightness, good weather resistance, and chemical stability. This pigment is primarily composed of zinc sulfide (ZnS) and barium sulfate (BaSO4), which are combined in a specific ratio to achieve the desired color and performance.
Titanium dioxide is produced in two main forms. The primary form, comprising over 98 percent of total production, is pigment grade titanium dioxide. The pigmentary form makes use of titanium dioxide’s excellent light-scattering properties in applications that require white opacity and brightness. The other form in which titanium dioxide is produced is as an ultrafine (nanomaterial) product. This form is selected when different properties, such as transparency and maximum ultraviolet light absorption, are required, such as in cosmetic sunscreens.
Titanium dioxide has a number of unique characteristics that make it ideally suited to many different applications.
Earlier this year, a bill was introduced in the California legislature to ban the manufacture, sale and distribution of foods in the state containing titanium dioxide, along with four other harmful food chemicals.
One of the key advantages of using nano titania in coatings is its superior UV resistance. Nano titania can effectively absorb and scatter UV radiation, providing enhanced protection against UV-induced degradation of coatings. This property makes nano titania an ideal choice for exterior coatings exposed to sunlight, such as automotive coatings, building coatings, and marine coatings.
