Heading: Science for ceramic production

In the investigated rocks of talc stone (carbonate-chlorite-talc composition) and accompanying tremolite-chlorite rocks in the temperature range of 950-1100 ° C, the following processes occur: dehydration (talc, tremolite, chlorite), decarbonatization (dolomite, calcite, breinerite) and the formation of new crystalline phases (forsterite, enstatite, clinoenstatite, subcalcium augite) due to the decomposition of talc and tremolite. These processes, as well as the presence of an amorphous phase enriched in magnesium cations, increase the strength of the ceramic. An additional factor for increasing the strength is the larger, slightly changed grains of tremolite due to the tabular and acicular shape, which have a reinforcing effect on the structure of the ceramics. Tab. 3, ill. 2, bibliography: 10 titles.
