Titanium dioxide

Titanium dioxide is a white, odorless, and insoluble substance that occurs naturally in several mineral forms, such as rutile and anatase. It is widely used as a pigment for various products, such as paints, plastics, cosmetics, and food. It also has some applications in nanotechnology and photocatalysis. Titanium dioxide has the chemical formula TiO2 and the molecular weight of 79.866 g/mol.

Strontium carbonate

Strontium carbonate is a kind of carbonate salt derived from strontium, which has a powdery appearance that can be either white or grey. This substance exists in nature as a mineral called strontianite. Although it is not very soluble in water, it can become more soluble if the water is saturated with carbon dioxide. Despite being a weak base, it can react with acids. Strontium carbonate is utilized in a variety of applications, including the production of strontium nitrate, ceramics, glass, fireworks, and isotopic analysis.
