• High manganese dioxide (MnO₂) content for reliable natural MnO₂ pyrolusite powder for clay brick coloring performance and consistent hue development.

• Uniform particle size improves dispersion in clay mixes and minimizes segregation during handling.

• Low impurities (Fe₂O₃, SiO₂) reduce adverse effects on brick texture and mechanical properties.

• Good thermal stability supports high-temperature firing without excessive volatilization.

• Inorganic and non-toxic composition suitable for standard ceramic processing lines.

• Bulk and customizable size grades support automated feed and blending systems.

• Clay Brick Coloring: Provides grey to black coloration in clay brick bodies at firing temperatures (900–1200°C).

• Ceramic Tile Bodies: Used to modify shade and visual texture in floor and wall tiles.

• Refractory Products: Acts as a functional additive in low-iron refractory bricks where controlled reduction potential is needed.

• Construction Ceramics: Incorporation in architectural clay products for aesthetic finish and uniform color outcome.

Supplied in 25 kg multiwall kraft bags with inner PE liners, suitable for bulk palletization and container export. Available in 1 MT, 2 MT, and tailored packaging configurations to match logistics requirements. Export-ready documentation and packaging meet international freight standards for safe long-distance transport.

Particle size distribution, bulk density, and impurity profiles can be adjusted within technical limits to meet specific process needs. Technical support available for formulation advice, trial blending parameters, and integration into existing clay brick production lines.
