Cross tee ceilings also offer flexibility in design. The grid pattern not only enhances the aesthetics but also allows for a variety of finishes and textures. Building owners can experiment with different tile colors and designs, giving them the freedom to adapt the atmosphere of a space according to its function—be it professional, casual, or welcoming.

4. Wood Panels For those seeking a warm and inviting atmosphere, wood panels provide a natural look that enhances interior décor. These materials can significantly improve the acoustic quality of a space. However, wood requires careful maintenance and treatment to prevent warping and damage due to humidity.

- The demand for rutile titanium dioxide has been on the rise due to its excellent properties, including high brightness, weather resistance, and chemical stability. These characteristics make it an ideal choice for various industries that require durable and long-lasting products. As a result, China's rutile titanium dioxide industry has been growing rapidly, with production capacities expanding to meet the ever-increasing demand.

In the meantime, the chemical factories of Continental Europe, principally in Germany, Austria and Belgium, had taken hold of the novelty and under the collective name of lithopone or lithophone, by numerous processes, produced various grades of the pigment, branding the respective qualities as red seal, green seal, yellow seal, blue seal, etc., or selling them under some fancy name. Of this we shall speak later on. The crusade against the use of white lead in the various countries of Continental Europe, assisted the manufacturers, to a very great extent, in marketing their products, not only to industrial concerns, as has been the case in this country, until recently, but to the general painting trade. Up to 1889 the imports into this country were comparatively small. At that time one of the largest concerns manufacturing oilcloth and linoleum in the State of New Jersey began to import and use Charlton white. Shortly after that other oilcloth manufacturers followed suit, replacing zinc white with lithopone in the making of white tablecloth, etc., and later on abandoning the use of white lead in floor cloth and linoleum. This gave an impetus to several chemical concerns, that erected plants and began to manufacture the pigment. Competition among the manufacturers and the activity of the importers induced other industries to experiment with lithopone, and the shade cloth makers, who formerly used white lead chiefly, are now among the largest consumers. Makers of India rubber goods, implement makers and paint manufacturers are also consumers of great quantities, and the demand is very much on the increase, as the nature of the pigment is becoming better understood and its defects brought under control. Large quantities find their way into floor paints, machinery paints, implement paints and enamel paints, while the flat wall paints that have of late come into such extensive use owe their existence to the use of lithopone in their makeup.

There is some concern regarding skin and intestinal absorption of titanium dioxide nanoparticles, which are less than 100 nm in diameter.
CSPI’s Chemical Cuisine is the web’s definitive rating of the chemicals used to preserve foods and affect their taste, texture, or appearance. Besides titanium dioxide, the group recommends avoiding artificial sweeteners like aspartame, acesulfame potassium, and sucralose, as well as synthetic food dyes like Yellow 5 and Red 3. CSPI and others have recently asked the Food and Drug Administration to ban the latter dye in foods and ingested drugs because the FDA has already determined that it is a carcinogen unsafe for use in cosmetics.
Because of health risks, France banned titanium dioxide as a food additive in 2020. Two years later the European Union also banned titanium dioxide as a food additive.
In recent years, there has been growing interest in the development of novel applications for Chinese anatase titanium dioxide, such as in the field of energy storage and conversion. For example, it has been investigated as a potential electrode material for lithium-ion batteries, due to its high conductivity and stability. Furthermore, its photocatalytic activity has been explored for use in dye-sensitized solar cells, where it can help to improve the efficiency of solar energy conversion.
6. What happens next?
Titanium dioxide is used in an enormous range of food products, which can feel jarring when looking at some of its other uses.

Recent analyses of food-grade TiO2 samples have found that a significant portion of particles may be within the nanoscale. These particles (also known as nanoparticles) range in size from 1 to 100 nm, where 1 nm equals 1 billionth of a metre (the width of a typical human hair is 80,000 to 100,000 nm).

Lithopone factory: Natrosol has some characteristics
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.
The brands of lithopone of the normal class, that of chemical manufacture, are marketed under such names as Ponolith, Beckton White, Jersey Lily White, Oleum White, Zinc Sulphide White, all of these being of domestic manufacture, and their composition is of the 30 per cent. zinc sulphide type. The German manufacturers and exporters of lithopone make use of fancy names for their brands and here are a few examples of these and the composition of the pigment:-
Titanium dioxide is used in the production of paper and textiles to improve whiteness, brightness, opacity and durability. It’s often used in fabrics, yarns, paper and other fibers.
