Transformation of aragonite to calcite through heating

  title={Transformation of aragonite to calcite through heating},
  author={S. Yoshioka and Y Kitano},
DTA-TG study on several aragonites was carried out to clarify the transformation of aragonite to cal cite through heating process. Aragonite formed in biological system started and completed the transforma tion at temperatures lower than did aragonite formed in inorganic systems. The DTA-TG study showed that weight loss was observed at the appearance of endotherm for coral aragonite and inorganically syn thesized aragonites, where the release of water during heating was recognized.
