13463-67-7 titanium dioxide using for coating manufacturer

The lithopone manufacturing process typically involves several key steps, including raw material preparation, calcination, grinding, classification, and packaging. Raw materials, primarily zinc sulfide and sulfuric acid, are carefully selected and mixed in a controlled environment to ensure uniformity. The mixture is then fed into a calcination furnace, where it undergoes a high-temperature reaction to produce zinc sulfide.

TiO2 comes in many different forms. However, only a few of these forms are considered food-grade (acceptable to be added to food). Many studies that raised concern about the safety of TiO2, including the concern for genotoxicity, used forms of TiO2 that are not considered acceptable for use in food and have different properties than food-grade TiO2. Other studies did use food-grade TiO2, but took steps to break the material down into smaller particles than what would normally be found in food.
