Calcination of industrial products
Calcination in production
The term calcination is derived from the Latin word calx. The term refers to the decomposition of calcium carbonate (CaCO3) and its conversion to calcium oxide (CaO) with the release of carbon dioxide (CO2). The term calcination was once also used for other processes in which metal carbonates or metal hydroxides are decomposed by heat, metal oxides are formed and water vapor or CO2 is released.
Today the term calcination is used in an even more general sense. The term is often equated with processes used to heat, decompose, dehydrate and decarbonize products. Calcination can thus be defined as all processes in which a solid is heated and thereby converted into another solid, accompanied by the release of gases. These gases mostly consist of H2O, or CO2. The most prominent examples of modern calcination processes are listed below:
- Calcination of lithium metal oxides from their carbonate or hydroxide components
- Calcination of inorganic color pigments (often based on Cd, Ti, Ni or Sb systems)
- Calcination of catalyst systems containing heavy metals
Our engineers also have the right solution for many other sophisticated calcination processes.
