What Do you Know About
IRON OXIDE ?
Iron oxide pigments are chemical compounds derived from iron and oxygen. They are produced through various methods, including the oxidation of iron salts or by heating iron compounds such as ferrous sulfate or ferric hydroxide.
Controlling
& Adjustment
The creation of iron oxide pigments is a refined process that involves dehydrating and calcining hydroxide precursors at high temperatures. The resulting pigment's hue is meticulously controlled by adjusting reaction conditions such as temperature, pH, and the addition of specific additives. This manipulation allows for a broad spectrum of colors to be achieved, ranging from red-orange to yellow, brown, black, and green. Each parameter influences the pigment's crystalline structure and surface properties, resulting in a palette of diverse and vibrant hues.
Special Raw
Material
The synthesis of General iron oxide pigments entails a meticulously orchestrated chemical transformation commencing with the amalgamation of ferrous sulfate solution and sodium hydroxide solution. This amalgamation instigates a precipitative response, whereby the constituents react in concert, giving rise to a distinct precipitate, predominantly manifesting as green ferrous hydroxide. Subsequently, this nascent precipitate undergoes a transformative metamorphosis catalyzed by atmospheric oxygen or other efficacious oxidizing agents. This oxidative metamorphosis engenders the conversion of ferrous hydroxide into the sought-after ferric hydroxide, thus culminating in the formation of the desired General iron oxide pigments.

UV resistance-Non toxic-Human Friendly
Iron oxide pigments offer numerous advantages and positive attributes across various industries. Firstly, they provide exceptional color stability, retaining their vibrancy and hue over time, even when exposed to harsh environmental conditions such as UV radiation and extreme temperatures. This durability ensures long-lasting coloration in applications like paints, coatings, plastics, and concrete.
Furthermore, iron oxide pigments are chemically inert, non-toxic, and environmentally friendly, making them safe for use in a wide range of applications, including those involving contact with humans, animals, and food products. Their inert nature also contributes to excellent weather resistance, corrosion resistance, and chemical stability, enhancing the longevity and performance of products they are incorporated into.
Easy to Use-Easy to Mix
Iron oxide pigments are easy to use and mix due to their fine particle size, chemical stability, and compatibility with binding agents. They disperse well in mediums like paints, coatings, plastics, and concrete, ensuring smooth mixing and even distribution. With excellent covering power, they require minimal pigment for desired colors, making them cost-effective. Additionally, their stability in formulations maintains color intensity over time, resisting UV radiation, chemical exposure, and environmental conditions, ensuring long-lasting coloration and durability. Overall, these qualities make iron oxide pigments preferred choices for diverse coloring applications.
