The following processes occur in talc stone (carbonate-chlorite-talc composition) and accompanying tremolite-chlorite rocks, studied in the present work, in the temperature interval 950 – 1100°C as a result of the decomposition of talc and tremolite: dehydration (talc, tremolite, chlorite), decarbonization (dolomite, calcite, breunnerite), and formation of new crystalline phases (forsterite, enstatite, clinoenstatite, subcalcium augite). These processes, as well as the presence of an amorphous phase enriched with magnesium ions, make ceramics stronger. Larger-size little-changed grains of tremolite are an additional strength-increasing factor. Owing to their tablet and needle shapes such grains reinforce the ceramic structure.
