Abstract
This report describes thermal decomposition behavior of asbestos including chrysotile analyzed by using TG-DTA and other analytical instruments. Heating process at least at 1100°C is required in order to dissolve asbestos into harmless minerals. Heating treatment of asbestos at 700°C mixed with chlorofluorocarbon waste is proposed as a new low temperature treatment of asbestos to make products harmless. Thermal analysis will be playing more important role in the development of methods to render asbestos harmless.
