Iron Oxide Red, Pharmaceutical Grade
Overview
Iron Oxide Red (Auxiliary Grade) is an inorganic compound primarily used as a pigment due to its vibrant red hue and stability. It is synthesized through thermal decomposition or precipitation methods, ensuring consistent quality for industrial applications. Unlike cosmetic or pharmaceutical grades, the auxiliary grade focuses on cost-effectiveness while maintaining performance in bulk applications like construction and coatings. This pigment is favored for its non-toxic nature and compliance with environmental regulations, making it a sustainable alternative to synthetic dyes. Its inert properties ensure longevity in end products, resisting fading under UV exposure or harsh weather conditions.
Physical and Chemical Properties
Iron Oxide Red exhibits a high density (5.24 g/cm³) and decomposes at 1565°C without boiling. Its insolubility in water and organic solvents makes it ideal for outdoor applications, while its compatibility with strong acids allows for specialized uses in chemical processes. The powder form typically has a particle size of 1–5 µm, ensuring uniform dispersion in matrices like paint or concrete. Key chemical properties include oxidation resistance and minimal reactivity with other materials, which prevent degradation over time. These traits are critical for applications requiring durability, such as architectural coatings or automotive plastics.
Main Applications
The construction industry is the largest consumer of Iron Oxide Red, where it colors concrete, pavers, and roofing tiles. Its UV resistance ensures long-lasting vibrancy in exterior applications. In coatings and paints, it provides opacity and corrosion protection, often used in primers and industrial finishes. Plastics and rubber industries utilize this pigment for items like hoses, flooring, and packaging, benefiting from its heat stability during processing. Lesser-known uses include cosmetics (e.g., blushes) and ceramics, where its non-toxicity and fine particle size are advantageous.
Safety and Storage
While Iron Oxide Red is generally safe, prolonged exposure to dust may cause respiratory irritation. Workers should wear NIOSH-approved masks and gloves during handling. Storage requires airtight containers to prevent moisture absorption, which can affect dispersion properties. Regulatory compliance varies by region; for example, the EU REACH regulation classifies it as non-hazardous. However, suppliers must provide Safety Data Sheets (SDS) detailing handling protocols. Spills should be cleaned with water to avoid airborne particles.
B2B Procurement Guide
Bulk buyers should prioritize suppliers with ISO 9001 certification to ensure consistent quality. Key specifications to request include Fe₂O₃ content (≥96%), residue on sieve (≤0.5%), and oil absorption value (15–25 g/100g). Testing samples for color consistency and dispersibility is recommended before large orders. Logistics considerations include moisture-proof packaging (e.g., 25-kg bags with inner liners) and cost-effective shipping options like bulk containers for international trade. Long-term contracts may secure stable pricing, especially given fluctuations in raw material costs.
