The epitaxial requirement for the selection of metastable arogonite among the polymorphs of calcium carbonate has been studied. Under calcite‐favorable conditions, the critical epitaxial strain with aragonite‐type inorganic substrates was found to be in the range 5–7 %. The Figure shows aragonite “fuzz” grown on SrCO 3 crystals that were aligned and fractured perpendicular to the alignment axis.
