Abstract

Abstract The transformation of synthetic diopside into chrysotile was achieved by hydrothermal reactions in the presence of MgO and MgCl2-6H2O at p(H2O) = 1 kbar in the temperature range 250°-390°C. The reaction progress was controlled by hydrothermal runs performed at 300°C and with reaction times ranging from 1 to 12 days. The habit of most chrysotile fibers is cylindrical, but other habits were also noticed. The fiber length and quality depend on temperature and reaction time. The accompanying phases, among which is lizardite, are also described
