Study on Decomposition and Transformation of Calcite-1 by Shearing at High Pressure | Chapter 05 | Recent Trends in Chemical and Material Sciences Vol. 5

 Transmission Calcite-1 was gently sheared at high pressure up to 16 GPa parallel to the (101) plane and in the [2-1-1] direction at room temperature, resulting in X-ray diffraction patterns on imaging plates. There were 22 large diffused circles visible. We may say that the produced chemicals are in an amorphous state based on the appearance of the rings. Except for graphite2H, CaO, and CaC2, the patterns revealed that majority of the rings do not relate to calcite-1, but to high-pressure compounds. They were supposed to have formed as a result of the polymorphism's disintegration and transformation. Atmospheric pressure is maintained. Despite the fact that the aforementioned results appear to contradict scientific consensus, the text mentions phenomena that support the findings. A compound decomposes into simple substances and compounds made up of the original complex's constituents when subjected to severe discontinuous dry rubbing. Calcite-I, when sheared at high pressure, not only changed its polymorphism but also broke down into compounds and simple chemicals.
