General description

Calcium carbonate is an inorganic compound that is sparingly soluble in water but highly soluble in dilute acids. It plays a crucial role in material science, particularly in the development of solar cells, batteries, and supercapacitors. In solar cell, it acts as a precursor material for the perovskite layer, enhancing the stability and performance of perovskite solar cells. Additionally, calcium carbonate is utilized in electrode production, serving as a conductive additive in cathode or anode materials, thus improving overall battery performance and durability.

Application

Calcium carbonate can be used as:     
  • A template, graphitization catalyst, and activating agent in the green synthesis of porous graphitic carbons from coal tar pitch for high-performance lithium-ion batteries.     
  • A raw material to synthesize calcium titanate (CaTiO3) perovskite material through sintering with titanium oxide (TiO2) by the sol-gel method. Calcium titanate can be used to create large-scale, low-cost, and sustainable solar cells.
  • A catalyst supports for improving the performance and durability of fuel cells, thereby contributing to the advancement of clean energy technologies.

The mineralization of perfluorinated alkyl substances (PFASs) by calcium compounds during the waste thermal treatment was systemically studied. Different calcium compounds showed different mineralization efficiencies of PFASs during the thermal process, owing to the different reaction mechanisms. Calcium hydroxide was

An organic matrix consisting of a protein-polysaccharide complex is generally accepted as an important medium for the calcification process. While the role this "calcified organic matrix" plays in the calcification process has long been appreciated, the complex mixture of proteins

The often astonishing material properties of crystalline biominerals are generally related to the hierarchical assembly of specifically interacting organic and inorganic components. To synthesize new materials with similar advanced properties applying nature's biomimeralization strategies we need to unravel the mechanisms

Although the polymorphism of calcium carbonate is well known, and its polymorphs--calcite, aragonite, and vaterite--have been highly studied in the context of biomineralization, polyamorphism is a much more recently discovered phenomenon, and the existence of more than one amorphous phase
