Abstract
The author analyzes the various possibilities of DTA as well as conventional installation set-ups. He shows that by varying simultaneously the heating rate and the size of the samples it is possible to obtain very similar thermo-grams. He shows the advantages of using fast heating rates and proposes a type of oven and types of crucible which allow heating rates of over 1 deg. per second, rapid manipulation, a controlled atmosphere (from a vacuum up to high pressures) and forced cooling. He gives details of research carried with this type of installation showing the quantitative nature of the analyses and, as an example, studies the influence of a grinding on the qualitative and quantitative results. (author) [French] L'auteur analyse les differentes possibilites de l'ATD ainsi que les schemas classiques des installations. Il montre qu'en jouant simultanement sur la vitesse de chauffe et les dimensions des echantillons on peut ne pas modifier beaucoup l'allure des thermogrammes. Il fait ressortir l'interet de grandes vitesses de chauffe et propose un type de four et des creusets permettant des vitesses de chauffe superieures a 1 deg. par seconde, une manipulation rapide, le controle de l'atmosphere (du vide jusqu'a de hautes pressions) et un refroidissement
