Calcium carbonate powder and titanium dioxide are commonly used inorganic chemical products, although both in paint, ink, paper, ceramics and other fields have a wide range of applications, but the two are different products. Xiaobian distinguishes the two products in detail from the components, molecular formulas, properties and other aspects of the two.

1. Main components: The main component of calcium carbonate is calcite; The main component of titanium dioxide is titanium dioxide (TiO2).

2. Molecular formula: The former molecular formula is CaCO? ; The latter molecular formula is TiO2.

3. Properties: The former is a compound, which is generated by the combination of calcium ions and carbonate ions, so it is both calcium salt and carbonate, neutral, basically insoluble in water, soluble in hydrochloric acid, exists in aragonite, calcite, chalk, limestone, marble, travertine and other rocks, and is also the main component of animal bones or shells; The latter is a polycrystalline compound with regular arrangement of particles and a lattice structure.

In practical applications, we can distinguish calcium carbonate powder and titanium dioxide from the above three aspects, so that the two products are correctly used in industrial production.
