Red clay powder supplier Indonesia high quality industrial clay

RED CLAY POWDER

Red Clay Powder is a finely processed natural mineral material derived from iron-rich clay deposits. Its distinctive red coloration is primarily attributed to high concentrations of iron oxide (Fe₂O₃), which also contributes to its chemical stability and durability. The material is mechanically processed through drying, crushing, grinding, and sieving to achieve uniform particle size distribution suitable for industrial and commercial applications.

Chemical Composition (Typical Range)

Component

  • SiO₂ (Silica) = 40 – 60%
  • Al₂O₃ (Alumina) = 10 – 25%
  • Fe₂O₃ (Iron Oxide) = 5 – 20%
  • CaO (Calcium Oxide) = 1 – 10%
  • MgO (Magnesium Oxide) = 1 – 5%
  • Moisture = 5 – 15%

The red color intensity increases with higher Fe₂O₃ concentration.

Physical Properties

  • Color: Reddish-brown to deep red
  • Particle Size: Typically 100–325 mesh (can be customized)
  • Texture: Fine, smooth, cohesive
  • Plasticity: Moderate to high when wet
  • Specific Gravity: ±2.4–2.6
  • Moisture Retention: < High
  • pH: Slightly acidic to neutral (5.5–7)

Mineralogical Structure

Common mineral constituents include:

  • Kaolinite
  • Illite
  • Montmorillonite
  • Iron oxides (Hematite)

The presence of hematite is primarily responsible for the red coloration.
