Kinetic studies in the CaO-SiO sub 2 system: II, Reaction rate constants and activation energies of selected diffusion couples

Various diffusion couples (C/ beta -C sub 2 S, C sub 2 S/CS, CS/S, C sub 3 S sub 2 /S) are annealed at different temps. Growth of mineral layers follows the parabolic rate law; from this, solid-state reaction rate constants and activation energies are calculated for C sub 3 S, C sub 2 S, C sub 3 S s...

Zusammenfassung:Various diffusion couples (C/ beta -C sub 2 S, C sub 2 S/CS, CS/S, C sub 3 S sub 2 /S) are annealed at different temps. Growth of mineral layers follows the parabolic rate law; from this, solid-state reaction rate constants and activation energies are calculated for C sub 3 S, C sub 2 S, C sub 3 S sub 2 , CS, and " CS sub 2 ."
