Calcium-carbonate powders were coprecipitated with Al3+ and then decomposed in air and/or under a CO2 flux between 590 °C and 1150 °C. The data were analysed using a consecutive-decomposition-dilatometer method and the kinetic results were discusse

This paper shows that the stiffness of styrene–butadiene solid rubber with added kaolin powder is related to the yield stress of kaolin dispersion in liquid polybutadiene rubber up to the percolation threshold. For five kinds of kaolin powder, the

Rheological measurements of four colloidal kaolin powders dispersed in water, paraffinic oil and liquid rubber have been done at solid concentration θ ( V S / V L ) in the range 8–33%. In quasi-static conditions the yield stress τ° values were d

Reaction between CaO powders and CO2(g) is often limited by slow diffusion of CO2 through the CaCO3 product. Additions of Li2CO3 are shown to increase the reaction rate. At temperatures around 940 K, near to the Li2CO3-CaCO3 eutectic temperature, 935

The changes in surface area and mesoporosity in aggregates of ∼0.01 μm cross-section CaO particles when heated in CO2at 686°C were determined from N2 adsorption isotherms. Initially, the surface area decreases rapidly with little change in porosi

This paper describes studies of incongruent vaporization reactions that were carried out in Berkeley and Genoa from 1970 to about 1987, but that have not previously been described in terms of the overall research objectives and the extent to which th
