What is the difference between titanium dioxide and lide powder?
Titanium dioxide (TiO2) is an important inorganic chemical products, in the paint, ink, paper, plastic rubber, chemical fiber, ceramics and other industries have important uses. Titanium dioxide (English name: titanium dioxide), the main component of titanium dioxide (TiO2) white pigment. The scientific name is titanium dioxide (titanium dioxide), and the molecular formula is TiO2, which is a polycrystalline compound with a regular arrangement of particles and a lattice structure. Titanium dioxide has the smallest relative density. The production process of titanium dioxide has two process routes: sulfuric acid method and chlorination method.
The lithopone is white crystalline powder. It is a mixture of zinc sulfide and barium sulfate. The more zinc sulfide, the stronger the hiding power and the higher the quality. Density 4.136~4.34g/cm3, insoluble in water. When exposed to acid, it is easy to decompose to produce hydrogen sulfide gas, and when exposed to hydrogen sulfide and alkali solution, it does not work. Irradiated by ultraviolet rays in sunlight for 6 to 7 hours, it becomes light gray and still restores its original color in the dark. It is easy to oxidize in the air, and caking and metamorphism after being affected with moisture.

Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth. It is named after Gaoling Village, Jingdezhen, Jiangxi Province.
Barium sulfate is based on barite as the main raw material, through beneficiation, ore washing, crushing and other processes. Barium sulfate has a hardness of 3~3.5 (Mohs) and a specific gravity of 4.3~4.7. It has the characteristics of high specific gravity, low hardness and brittleness. Barite is almost insoluble in water, ethanol and acid, soluble in hot concentrated sulfuric acid. With the development of some high-performance barium sulfate products, the application field of barium sulfate is constantly expanding.
