anatase titanium dioxide

In conclusion, the price per kilogram of titanium dioxide varies depending on several factors, including the production method, quality, purity, and demand. High-quality titanium dioxide produced through the chloride process tends to be more expensive than lower-quality titanium dioxide produced through the sulfate process. However, the sulfate process is more commonly used due to its lower cost and higher yield. As an essential pigment in various industries, titanium dioxide continues to play a crucial role in our daily lives.

A dense, white, opaque pigment composed of a mixture of Zinc sulfide (30%) and Barium sulfate (70%) with trace amounts of Zinc oxide. Lithopone, first produced in 1874, was called Orr's white.
