    Traditional in situ chemical oxidation is not a solution to persistent plumes because the reactants are relatively short-lived (Siegrist et al., 2011). Slow-release chemical oxidants, in theory, have the potential to treat persistent dioxane and associated chlorinated solvent plumes over an extended timeframe at a low cost. Delivery of the oxidant over short-screened intervals can reduce the displacement of contaminated ground water relative to injection over longer-screened intervals.

The oxidation behaviors and kinetics of in-situ ОІ-Sialon bonded Al2O3-C refractories were investigated by TGA techniques via isothermal oxidation experiments at different temperatures. The results show that the oxidation process of in-situ ОІ-Sialon bonded Al2O3-C refractories can be divided into three stages: oxidation reaction rate
