Key Features
Consistent Ceramic Coloration: Optimized for body stains and glaze pigments, providing stable color response in firing.
High Purity MnO₂: 98–99.5% manganese dioxide minimizes impurities that can cause off-tones or defects in glazes.
Controlled Particle Size: 2–8 μm distribution enhances dispersion and uniformity in stain and pigment mixes.
Low Iron Content: Reduced Fe₂O₃ ensures cleaner color outcomes and fewer interactions with other oxide colorants.
Easy to Disperse: Fine powder with balanced bulk density for predictable batching and mixing.
Thermal Stability: Performs reliably across typical ceramic firing schedules without volatilization or reduction.
Applications
Body Stains and Pigments: Ideal for formulating ceramic body stains with stable color yield after firing.
Glaze Colorants: Used in oxide colorant packages for glazes requiring manganese shades or modifiers.
Tiles & Sanitaryware: Suitable for large-scale ceramic tile and sanitaryware pigment production.
Porcelain & Earthenware: Provides consistent results in porcelain and earthenware bodies.
Refractory Color Systems: Incorporated into refractory stains where manganese hues are required.
