Origin

Our chalk deposits consisting of calciumcarbonate (CaCO₃) developed 70 to 100 million years ago - at the time of the dinosaurs. At that time wide areas of Europe as it is today were covered with the sea. In the coast shallows, enormous deposits from shells and skeletons of microbes formed. These sediments kept their relatively soft structure and, as a result, a natural raw material with many uses developed.

Characteristics

Chalk is amorphous, extremely fine, and can be easily distributed. This means that it is the ideal filler for use in industrial applications. Furthermore, the highly reactive calciumcarbonate of chalk is best-suited to be used as fertilizer lime in agriculture and forestry. For animal fodder, calciumcarbonate made from chalk is an excellent supplier of calcium. Moreover, the highly reactive chalk can be used for the flue gas desulfurisation and thus, it contributes to environmental protection.
