Inorganic Iron Oxide Red
Overview
Iron Oxide Red is an inorganic compound widely used as a pigment due to its vibrant red color and stability. It is chemically known as ferric oxide (Fe2O3) and is produced synthetically for consistent quality, though it also occurs naturally as hematite. This pigment is favored in industrial applications for its non-toxic nature, resistance to UV light, and compatibility with various binding agents. Its synthetic production allows for controlled particle size and purity, making it a reliable choice for manufacturers.
Physical and Chemical Properties
Iron Oxide Red is characterized by its bright red hue, high density, and insolubility in water. It exhibits excellent thermal stability, with a melting point of 1538°C, and remains chemically inert under normal conditions. The pigment's lightfastness and weather resistance make it ideal for outdoor applications. It is also resistant to alkalis and weak acids, though it dissolves in strong acids like hydrochloric acid. These properties ensure long-lasting color retention in finished products.
Main Applications
The primary use of Iron Oxide Red is as a coloring agent in construction materials such as concrete, bricks, and tiles. It provides durable coloration that withstands environmental exposure. In the coatings industry, it is used in paints, primers, and anti-corrosive coatings. Additionally, it finds applications in plastics, rubber, ceramics, and even cosmetics, where its non-toxic nature is advantageous.
Safety and Storage
While Iron Oxide Red is generally considered safe, prolonged exposure to dust can cause respiratory irritation. Proper ventilation and protective gear, such as masks and gloves, are recommended during handling. Storage should be in a dry, cool environment to prevent moisture absorption, which can affect the pigment's performance. Containers must be tightly sealed to avoid contamination and degradation.
B2B Procurement Guide
When procuring Iron Oxide Red, buyers should prioritize suppliers that provide detailed specifications, including purity, particle size, and chemical composition. These factors influence the pigment's performance in specific applications. Bulk purchases often offer cost savings, but it's essential to assess storage capabilities to maintain product quality. Requesting samples for testing can help ensure the pigment meets the required standards before large-scale procurement.
