As early as sixty years ago, zinc sulphide was first thought of as a pigment for coloring India rubber and a patent for the process of its manufacture was issued in England. But it was not until twenty years later that zinc sulphide and its manufacture was seriously considered as a pigment for paint, and in 1874 a patent was issued for a process of manufacturing a white pigment, composed of zinc sulphide and barium sulphate, known as Charlton white, also as Orr's white enamel. This was followed in 1876 by a patent issued to a manufacturer named Griffith and the product, which was similar in character to Charlton white, was known as Griffith's patent zinc white. In 1879 another patent for a more novel process was obtained by Griffith & Cawley, the product made under this process proving the best of the series placed upon the market up to that date. After that time many new processes were patented, all, however, tending to the same object, that of producing a white pigment, composed of zinc sulphide and barium carbonate, the results, however, in many cases ending with failure.
The CaCO3 and TiO2 factory not only provides a reliable supply of these materials to industries but also contributes to the local economy by creating job opportunities and generating revenue. The factory employs skilled workers in various departments such as production, quality control, and maintenance. It also collaborates with suppliers and distributors to ensure efficient transportation and delivery of CaCO3 and TiO2 to customers worldwide.
Titanium is one of the most common metals on earth, but it does not occur naturally in this elemental form. TiO2, also known as titanium (IV) oxide or titania, is the naturally occurring compound created when titanium reacts with the oxygen in the air. As an oxide, titanium is found in minerals in the earth’s crust. It is also found with other elements, including calcium and iron.
TiO2 is also used in paints and coatings due to its excellent whiteness, opacity, and weather resistance. It provides a durable and long-lasting finish that protects the underlying surface from environmental factors such as UV radiation, moisture, and chemicals. Finally, gravimetric analysis is a traditional method for determining barium in TiO2. This technique involves weighing the precipitate formed by reacting the sample with a reagent and then calculating the mass of barium present. Gravimetric analysis offers high accuracy and precision, but it is time-consuming and labor-intensive. The quotation aspect of this industry is equally intriguing
EFSA's evaluation is related to the risks of TiO2 used as a food additive, not to other uses.
Reason for listing: CNNC Huayuan Titanium Dioxide Co., Ltd., a well-known brand of titanium dioxide factory, started in 1989, specializing in the research and development, production, sales and service of titanium dioxide products. One of the titanium dioxide enterprises producing more than 10,000 tons.
In addition to these established players, several emerging suppliers are making their mark in the industry by offering innovative solutions and competitive pricing
FDA guidelines:Americans are eating too much salt. So the FDA wants food manufacturers to cut back on sodium.

1. Company AOn the other hand, titanium dioxide is a synthetic mineral that is produced through a chemical reaction involving the mineral ilmenite or rutile. It is used in industries such as cosmetics, paint, and sunscreen as a whitening agent and pigment. The manufacturing process of titanium dioxide involves extracting the mineral from ores, purifying it through chemical processes, and then grinding it into a fine powder.
Most food-grade titanium dioxide is around 200–300 nanometers (nm) in diameter. This size allows for ideal light scattering, resulting in the best color (1Trusted Source).
