L'Apatite Sulfo-Vanadocalcique: Preparation, Comportement Thermique
Phosphorus, Sulfur and Silicon and the Related Elements, 1989Abstract The preparation and the thermal behaviour of sulfovanadocalcium apatite. It is possible to prepare a sulfovanadoapatite by a gas/solid reaction at 700°C in a sulfur atmosphere. The substitution of a S2- ion and a vacancy for two divalent OH− ions in the hydroxyapatite Ca10(VO4)6(OH)2 leads to the sulfoapatite Ca10(PO4)6S□.

Comportement thermique d'un générateur à sorption solide
International Journal of Thermal Sciences, 1998Abstract The thermal behaviour of a solid sorption generator of active carbon/alcohol machine, is studied during heating and cooling phases with a preheated air flow. A bicylindrical walls generator that contains 0.9 kg of a granular adsorbent in the presence of residual gas is tested during a cycle of an average duration of 3 hours; the grains of ...

Comportement thermique de polyamides et polysulfonamides “semi-aromatiques”
European Polymer Journal, 1976Resume Differentes techniques (analyse thermique, dilatometrie, diffractometrie X, resonance magnetique nucleaire, spectrographie de masse, mesures electriques) ont ete utilisees pour etudier le comportement thermique de plusieurs polyamides et polysulfonamides “semi-aromatiques”. Trois phenomenes de transition ont ete mis en evidence et relies a des
