The high-temperature structural behaviour of talc, Mg3Si4O10(OH)2, deformed by compaction and shear was investigated for the first time by extending the temperature range to 1600°C. The deformation was induced with low mechanical load through a specifically built planetary ball milling working in a controlled thermodynamic …
