Uses
Industrial Applications of CAST IRON POWDER
1. Reduction-Grade Applications
- Purpose: Acts as a
reducing agent to extract oxygen from compounds.
- Industries: Metallurgy,
chemical reactions (e.g., lead/copper smelting).
2. Intermediate Chemicals Production
- Catalysts: Facilitates
chemical reactions.
- Pharmaceuticals:
Precursors for APIs.
- Dyes/Pigments: Colorant
synthesis.
- Agrochemicals:
Pesticides/fertilizer components.
3. Pharmaceuticals
- Reduction Reactions:
Converts nitro groups to amines (e.g., Bechamp reaction).
- Catalysis: Accelerates
drug synthesis.
- Iron Supplements:
Direct use in formulations (e.g., ferrous sulfate).
- Excipients: Inert
filler in tablets.
- Regulation: High-purity
grades required for compliance.
4. Lead Smelting
- Reduces PbO → Pb
(metallic lead).
- Desulfurizes PbS ores
(forms FeS).
- Purifies molten lead by
removing impurities.
5. Copper Smelting
- Slag Formation: Binds
impurities (e.g., silica, iron oxides).
- Matte Conversion:
Oxidizes FeS in copper matte.
- Alloying: Secondary use
in bronze/brass production.
6. Specialty Chemicals
- Catalysts:
Polymer/agrochemical production.
- Water Treatment:
Ferrous sulfate for coagulation.
- Magnetic Materials:
Electronics/data storage.
- Pigments: Iron oxides
for paints/coatings.
7. Cosmetic Chemicals
- Pigments: Iron oxides
(red/yellow/black) in makeup.
- Magnetic Masks: Skin
purification.
- Sunscreens: Enhances UV
protection.
- Special Effects:
Shimmer/metallic finishes.
8. Bechamp Reaction
- Process: Reduction of
nitro compounds (Ar-NO₂) to amines (Ar-NH₂) using iron powder, water, and acid.
- Byproduct: Iron(II)
hydroxide (Fe(OH)₂).
Key Applications
- Metal oxide reduction (e.g., copper, nickel, and precious metal recovery)
- Wastewater treatment (heavy metal removal)
- Hydrogen generation (iron-steam reactions)
- Powder Metallurgy – Sintered components for automotive and machinery.
- Welding & Coatings – Enhanced wear and corrosion resistance
