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%.
- There are several factors that set reputable titanium dioxide food grade suppliers apart from the rest. Firstly, they must adhere to strict regulatory standards and guidelines set by governing bodies such as the FDA (Food and Drug Administration) in the United States and the EFSA (European Food Safety Authority) in Europe. These regulations ensure that the titanium dioxide used in food products is safe for human consumption and does not pose any health risks.
- TIO2, or Titanium Dioxide, is an essential pigment in various industries, predominantly in paint, plastics, and cosmetics, due to its exceptional light-scattering properties and UV resistance. The procurement and manufacturing of TIO2 have become key aspects for businesses seeking high-quality raw materials while maintaining sustainability and efficiency.
The National Cancer Institute tested TiO2 for possible carcinogenicity by the oral route of exposure by feeding rats and mice with TiO2 (size not specified) at doses 25,000 or 50,000 ppm TiO2 for 103 weeks. They concluded that TiO2 was not carcinogenic.Also, the study with rats fed diets containing up to 5 % TiO2 coated mica for 130 weeks showed no treatment-related carcinogenicity. Since the size and other TiO2 properties were not specified or determined, we cannot generalize this conclusion and we have to take into account other possible outcomes of this scenario in different exposure conditions (other size/crystalline structure of TiO2 etc.).
Some small test-tube research has shown that these nanoparticles are absorbed by intestinal cells and may lead to oxidative stress and cancer growth. However, other research has found limited to no effects (13Trusted Source, 14Trusted Source, 15Trusted Source).
Titanium Dioxide Raw Material Tio2 Powder
The reaction liquid is filtered through plate and frame pressure to obtain lithopone in the form of a filter cake with a moisture content of no more than 45%. It is then roasted in a drying furnace to change the crystal form of lithopone, and is then pickled with sulfuric acid at a temperature of 80°C. Finally, it is washed with water, reinforced with colorants, filtered, dried and ground into powder.
2. Cosmetics With its UV-filtering properties, anatase TiO2 is a popular ingredient in sunscreens and cosmetic formulations. Its ability to scatter UV radiation effectively protects the skin from harmful sun exposure, contributing to the increasing popularity of natural and mineral makeup products.
This article discusses the discovery of phosphorescent lithopone on watercolor drawings by American artist John La Farge dated between 1890 and 1905 and the history of lithopone in the pigment industry in the late 19th and early 20th centuries. Despite having many desirable qualities for use in white watercolor or oil paints, the development of lithopone as an artists' pigment was hampered by its tendency to darken in sunlight. Its availability to, and adoption by, artists remain unclear, as colormen's trade catalogs were generally not explicit in describing white pigments as containing lithopone. Further, lithopone may be mistaken for lead white during visual examination and its short-lived phosphorescence can be easily missed by the uninformed observer. Phosphorescent lithopone has been documented on only one other work-to-date: a watercolor by Van Gogh. In addition to the history of lithopone's manufacture, the article details the mechanism for its phosphorescence and its identification aided by Raman spectroscopy and spectrofluorimetry.
TiO2 is typically thought of as being chemically inert, meaning it does not react with other chemicals and is, therefore, a stable substance that can be used in many different industries and for various applications.
The successful completion of 2022.

2. Market analysis
Product quotation
From the perspective of market development in 2022, prices in the first half of the year are basically in a stable stage, with little fluctuation, and prices in the second half of the year are in a rapid decline stage. In November, Longqi sent a letter to raise the price to stabilize the price. At this time, the price of titanium dioxide began to stabilize and stop falling.
In the first quarter, export orders performed well, and the market confidence of titanium dioxide enterprises was good. Before the year, domestic downstream manufacturers mainly hoarded goods moderately before the year. The market rose twice, with a cumulative increase of 1.77% from January to March. The ex factory quotation of domestic rutile titanium dioxide including tax is mostly 20000-22000 yuan/ton; The ex factory quotation of anatase titanium dioxide including tax is between 18000-19500 yuan/ton. After the year, the domestic raw material sulfuric ACID price continued to rise, the enterprise cost was under pressure, and the support was strong. The titanium dioxide market confidence was fair, and the price continued to rise.
In the second quarter, the logistics management and control and the domestic market turnover were light. Affected by logistics control and other factors, transportation is relatively difficult, market supply is shrinking, traders are unstable, and the market price declines with the focus on digesting their own inventory. The cumulative decline from April to June was 3.08%. The ex factory quotation of domestic rutile titanium dioxide including tax is between 19100-22000 yuan/ton; The ex factory quotation of anatase titanium dioxide including tax is between 17800-19000 yuan/ton. The spot market of titanium ore continued to decline, the price of sulfuric acid also continued to decline, and the cost support was weak. At the same time, the performance of the downstream terminal real estate market is poor. Under the superposition of multiple negative factors, the titanium dioxide market fell.
In the third quarter, Longqi guided the price reduction and the titanium dioxide market fell sharply. 7-9 The cumulative decline was 19.85%. The ex factory quotation of domestic rutile titanium dioxide including tax is mostly between 15500-17000 yuan/ton; The quotation of anatase titanium dioxide is between 14500-15500 yuan/ton. Due to the limited power supply and other factors, the titanium dioxide enterprises in southwest China have reduced their production. The market price of raw sulfuric acid fell rapidly, and the cost support was weak. In addition, the domestic titanium dioxide market demand continues to be sluggish, and the manufacturer's inventory pressure is still large.
In the fourth quarter, Dragon Enterprise sent a letter in November to promote stability. The cumulative decline was 2.55% from October 12. The titanium dioxide market is about to enter the off-season, and the demand market for coatings is tepid, especially in the northern market. In November, the group announced that the price would rise, and the prices offered by various manufacturers were flexible, so it was more meaningful to stop the decline. Most domestic rutile titanium dioxide prices are between 15000-17500 yuan/ton; The quotation of anatase titanium dioxide is about 14000-14500 yuan/ton. The price of titanium concentrate in Panxi increased. More than 20 domestic titanium dioxide enterprises sent letters to announce the increase, and the international giants Chemurs and Tronox announced the reduction of titanium dioxide production in the fourth quarter, which also benefited the domestic titanium dioxide market and stabilized the market on the whole.
