CARBONYL IRON Meaning and
Definition
-
Carbonyl iron is a type of iron powder that is produced through the process of carbonylation. It is a chemical compound consisting of ultrafine particles of iron, typically between 1 to 10 micrometers in size. The carbonylation process involves the reaction of iron pentacarbonyl (Fe(CO)5) with air and heat, resulting in the decomposition of iron pentacarbonyl and the formation of pure carbonyl iron particles.
Carbonyl iron is widely used in various applications due to its unique properties. It possesses high purity and a high surface area, making it highly reactive and easily dispersible in different types of mediums. It is commonly utilized as a raw material in the production of magnetic materials such as soft magnets, as well as in the manufacturing of alloys, catalysts, and in the production of powdered metals.
In the field of medicine, carbonyl iron is often used as an iron supplement due to its high bioavailability. It is easily absorbed by the body and utilized in the production of hemoglobin, an essential component of red blood cells. Furthermore, its small particle size allows for better dissolution and absorption, making it an efficient source of iron for individuals with iron deficiencies.
Overall, carbonyl iron is a fine powder of iron particles produced through the carbonylation process, which finds extensive use in various industries and in medical applications for its high purity, reactivity, and bioavailability.
Etymology of CARBONYL IRON
The word "carbonyl iron" comes from the combination of two terms: "carbonyl" and "iron".
The term "carbonyl" refers to a chemical compound that contains a carbon monoxide (CO) molecule bonded to a metal atom. It is derived from the suffix "-yl", which in chemistry is used to name organic radicals, combined with the word "carbon". Thus, "carbonyl" describes a compound containing a carbon monoxide group.
The word "iron" comes from the Old English word "īsern", which evolved from the Proto-Germanic word "īsarna" or "īsarnan", ultimately derived from the Proto-Indo-European root word *is-/*es-, meaning "metal". It has been used to refer to the metal element iron since ancient times.
