Sodium silicate solutions from dissolution of glasswastes. Statistical analysis

Abstract

It has studied the solubility process of four different waste glasses (with different particle sizes, 125 µm) in alkaline solutions (NaOH and NaOH/Na₂CO₃) and water as a reference and under different conditions of solubility (at room temperature, at 80°C and a mechano-chemical process). Have established the optimal conditions of solubility and generation of sodium silicates solutions, and these were: the smaller particle size (
