Does anyone know the difference between titanium dioxide, titanium slag and titanium dioxide?

Titanium dioxide is TiO2. Titanium dioxide is specially coated titanium dioxide. Without this special coating treatment, it is titanium dioxide. High titanium slag is a kind of "titanium-rich material" with increased titanium content, which is smelted from titanium concentrate. To put it bluntly, it is the raw material for producing titanium dioxide, which has high content and certain impurities.

In other words, titanium dioxide is a chemical name, high titanium slag is a raw material for production, and titanium dioxide is an industrial product.
