Titanium Dioxide Raw Material Tio2 Powder
Analyst Insight
Partial substitution of titanium dioxide in liquid paints
Titanium Dioxide prices in Germany increased by about 4% in the second quarter compared to what was seen in Q1 from historical price trends. Due to the restrictions on Russian energy imports brought on by the sanctions imposed by European countries, domestic production of TiO2 saw its costs surge even further. Additionally, the commodity's price was highlighted and its market expansion was supported by the upstream construction and automation sectors' buoyant demand.
IMARC Group’s report, titled “Lithopone Manufacturing Plant Project Report 2024: Industry Trends, Plant Setup, Machinery, Raw Materials, Investment Opportunities, Cost and Revenue” provides a complete roadmap for setting up a lithopone manufacturing plant. It covers a comprehensive market overview to micro-level information such as unitoperations involved, raw material requirements, utility requirements, infrastructure requirements, machinery and technology requirements, manpower requirements, packaging requirements, transportation requirements, etc. The lithopone project report provides detailed insights into project economics, including capital investments, project funding, operating expenses, income and expenditure projections, fixed costs vs. variable costs, direct and indirect costs, expected ROI and net present value (NPV), profit and loss account, financial analysis, etc.
1: Flocculation principle
While IARC listed titanium dioxide as “possibly carcinogenic to humans,” they also add that “there is inadequate evidence in humans for the carcinogenicity of titanium dioxide.” Of the four human studies that they reviewed, only one showed a potential risk for occupational workers inhaling titanium dioxide particles and lung cancer, while the other three showed no risk for cancer at all. And it’s key to note that IARC did not assess the effects of titanium dioxide found in foods.

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.
Although the evidence for general toxic effects was not conclusive, on the basis of the new data and strengthened methods our scientists could not rule out a concern for genotoxicity and consequently they could not establish a safe level for daily intake of TiO2 as a food additive.

The year 2016 had shown a strong rebound of China’s TiO2 business in general, according to market intelligence firm CCM. The market situation in 2015 was quite depressed, while in 2016 huge price rises have benefited the financial performance of China’s manufacturers.
