Rankinite synthesis and pyrolysis inversion

The thermal transformation of the pyrolysis–condensation–rankinite synthesis process at a normal pressure is considered in detail. Rankinite pyrolysis is performed with a step-by-step increase in enthalpy (TERRA software system). Rankinite pyrolysis compounds are condensed on a surface with temperature $T = 298.15$ K. Condensate compounds are equivalent to pyrolysis compounds. Wollastonite and limestone can precipitate upon condensation to form a mineral deposit. Synthesis is performed by mixing the condensate compounds. The compounds and heat of chemical reactions, the enthalpy, the temperature, and the heat content have been determined. It has been shown that the decomposition of rankinite $(T_{\rm dec} = 2598.36$ K$)$, wollastonite $(T_{\rm dec} = 3662.7$ K$)$, and limestone $(T_{\rm dec} = 3680$–$3810$ K$)$ occurs in the process of synthesis and pyrolysis at a constant temperature. The complete pyrolysis–condensation–synthesis process picture typical for various compounds is given.
