Glass Grade Manganese Dioxide as a Decolorizing Agent
Short Product Description
Glass Grade Manganese Dioxide as a Decolorizing Agent is a high-purity MnO₂ material (MnO₂ ≥ 88–92%) designed for glass manufacturing applications. It is used to neutralize the green tint caused by iron impurities and improve optical clarity in flat, container, and specialty glass production.
