MnO2 Powder for Neutralizing Green Tints in Glass
Short Product Description
MnO2 Powder for Neutralizing Green Tints in Glass is a high-purity manganese dioxide grade (MnO₂ ≥ 85–92%) used as a decolorizing agent in glass manufacturing. It oxidizes ferrous iron (Fe²⁺) to ferric iron (Fe³⁺), reducing green coloration and improving optical clarity in flat and container glass production.
