Introduction to Iron Oxide Black CAS 12227-89-3
Iron Oxide Black, also known as ferric oxide black or black iron oxide, is a widely used pigment in various industries. With the CAS number 12227-89-3, it is a chemical compound that has been extensively studied for its unique properties and applications. This pigment is derived from iron oxide, which is a naturally occurring mineral. The black color is achieved through the reduction of iron oxide, resulting in a fine powder that is highly stable and durable.
Chemical Composition
Iron Oxide Black is primarily composed of iron (Fe) and oxygen (O), with the chemical formula Fe3O4. This compound is known for its high iron content, which contributes to its black color and magnetic properties. The iron oxide particles are typically in the form of fine powders, which can be easily dispersed in various mediums. The purity of the pigment can vary, with grades ranging from 99% to 99.9%, depending on the intended application.
Physical Characteristics
The physical properties of Iron Oxide Black make it a versatile pigment. It has a particle size that ranges from 0.1 to 0.5 micrometers, which allows for excellent dispersion in paints, inks, and plastics. The pigment is known for its high opacity, which is crucial for applications where a deep black color is required. Additionally, Iron Oxide Black is highly stable, with a melting point of around 1560 degrees Celsius, making it suitable for high-temperature applications.
Applications in Paints and Coatings
One of the primary applications of Iron Oxide Black is in paints and coatings. Its deep black color and high opacity make it ideal for creating a wide range of finishes, from matte to glossy.
