Resumo: A new ceramic material ‘‘Vikaflex Ⓡ’’ was de- veloped from industrially pyrolized shale solid residue. Thermal properties of this material were studied by thermal microscopy, TG, DTG and DTA analyses at temperature from 400 to 1,400 °C. The thermal expansion coefficient was estimated from the heating microscope images for the solid phase before losing its shape using an improvement of a previous method. The specific heat capacity and mass change between 600 and 1,100 °C were detected. This porous solid material shows high thermal stability up to 1,050 °C.
