Abstract
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 of calcium carbonate in biominerals has only very recently been understood. Here we summarize what is known about polyamorphism in calcium carbonate as well as what is understood about the role of amorphous calcium carbonate in biominerals. We show that consideration of the amorphous forms of calcium carbonate within the physical notion of polyamorphism leads to new insights when it comes to the mechanisms by which polymorphic structures can evolve in the first place. This not only has implications for our understanding of biomineralization, but also of the means by which crystallization may be controlled in medical, pharmaceutical, and industrial contexts. Coming in to form: A summary is given of what is known about polyamorphism in calcium carbonate as well as the role of amorphous calcium carbonate in biomineralization. The amorphous forms of calcium carbonate within the physical notion of polyamorphism lead to new insights when it comes to the mechanisms by which polymorphic structures can evolve. This also has implications beyond biomineralization.
