Ananías Gèrard Janin Agrociencias heat treatment Dinizia excelsa Chemical analysis dimensional stability technological properties This study had the objective to heat treated angelim vermelho (red) wood and then to analyze its effects on the physical, mechanical and chemical properties of the wood. The wood was treated at 180 ºC and 215 °C for 20 min and 40 min in a muffle furnace. The basic density, shrinkage, anisotropy, the modulus of rupture and modulus of elasticity, as well as the holocellulose, lignin, extractives and ash content values were obtained for the treated and untreated (control) wood. The results indicated that the basic density was not changed and there was a decrease in volumetric shrinkage in the most severe treatment. The modulus of rupture did not change and the chemical analysis indicated a decrease in the holocellulose and extractives content resulting in lignin content percentage increase, mainly in the most severe test. 2023 artículo científico 0717-3644 https://www.redalyc.org/articulo.oa?id=48575202010 https://www.redalyc.org/journal/485/48575202010/ https://www.redalyc.org/journal/485/48575202010/html/ https://www.redalyc.org/journal/485/48575202010/48575202010.epub https://www.redalyc.org/journal/485/48575202010/movil 10.4067/s0718-221x2023000100410 en http://www.redalyc.org/revista.oa?id=485 Maderas.
