In sorbent-flue-gas reactions, porous CaO sorbent particles are used to capture SO{sub 2} by formation of CaSO{sub 4}. Because of the large molar volume of CaSO{sub 4}, the internal surface area which is originally available for reaction diminishes a

Major revisions in the enthalpies and Gibbs energies of formation of calcium oxide and magnesium oxide are presented. In free-evaporation experiments over the temperature range of 1830 to 2070 K, the kinetics of vaporization of calcium oxide and magn

A counter-current gaseous diffusion model is presented to describe the oxidation of hafnium carbide between 1200 and 1530°C. The model separates the porous hafnia scale into two gas diffusion regions separated by a flame front, where O 2 and CO reac

The oxidation behavior of HfC, HfC-25 wt. % TaC, and HfC-7 wt.% PrC2 has been studied between 1200–2200° C. Parabolic growth of the oxide layer has been observed for both HfC and HfC-TaC over the entire temperature range. A break in the temperatur

Solubility curves, pct Ovs pct Al, representing the saturation of iron with A12O2, include both minimum and maximum points. In this article, it is shown that a two-parameter exponential form of logfo as a function of pct Al represents the Al-O cluste

The papers on the oxidation kinetics are reviewed to clarify the rate-controlling steps and the micromechanisms of oxidative attack. In the first part of the report, the general oxidation behavior of c/c composites is presented and then the detailed

Sintered, fine-grained ferric oxide (Fe2O3) with a porosity of 11.4 pct was used as a solid material in the present investigation of the rate of carbon monoxide decomposition in the presence of water vapor at temperatures of 430, 475, 513, 550 and 59
