摘要: Reactions between silica and graphite were studied in vacuum from 1445° to 1765°C by continuously measuring the amount of carbon monoxide formed. At low temperatures and/or short times, reaction followed a linear rate law with an apparent activation energy 117 kcal. higher longer showed more complex behavior, indicative nucleation-growth process 122 It is shown that could proceed via gas phase dissociation into oxygen silicon subsequent graphite. The onset nucleation-growth-controlled be correlated transformation quartz cristobalite.
