Abstract
Thermal change of an ecological carbon/carbon hybrid material, wood ceramics (WC) prepared from apple pomace, was studied for the first time by mainly using TG-DTA/MS. Dehydration and release of gaseous carbon dioxide (CO2) occur in temperatures lower than ca. 483K; CO2 and fragments of phenol resin are mainly found up to 943K; at higher temperatures, gaseous CO is discharged, showing progressive carbonation. Carbonized materials and Woodceramics sintered at 1073K shows maximum evolution of adsorbed gases, and show dehydration immediately followed by CO2 evolution at temperatures lower than 483 K; but Woodceramics is thermally more stable than carbonized materials and the gas evolution peak temperatures are higher for products sintered at higher temperatures.
