The kinetics of the vitreous silica-molten silicon reaction in the 1430∼1620°C temperature range are investigated. The activation energy for the rate of solution of silica, ΔH, was found to be 57±3 kcal/mol. The rate determining step for this reaction is the diffusion process.There is no past data for the heat of solution of oxygen in molten silicon in the presence of silica, ΔHsoll. It was estimated by thermodynamical analysis that ΔHsoll≈ΔHsols+7 kcal/mol, where ΔHsols is the heat of solution of oxygen in solid silicon in the presence of silica. Using the above relation and Logan and Peters’ value for ΔHsols=53±7 kcal/mol(6), it is estimated that ΔH≈ΔHsoll. According to Taft and Horn(2), however, ΔH is 31 kcal/mol, and this value is also consistent with ΔH≈ΔHsoll, if Hrostowski and Kaiser’s value for ΔHsols=23±3 kcal/mol(7), is used.
