The resulting material can vary in terms of its crystal structure and composition, affecting its properties and potential applications. Overall, niobium nitride is a versatile compound with diverse applications in fields that demand its unique combination of properties, including high hardness, thermal stability, electrical conductivity, and superconductivity.
Etymology of NIOBIUM NITRIDE
The word "niobium" comes from the Greek mythological figure Niobe, who was the daughter of Tantalus. Niobe's story is associated with grief and sorrow, just as the element niobium was difficult to isolate and categorize for a long time. The element was initially known as columbium, named after Christopher Columbus due to its discovery in America. However, it was later renamed niobium to avoid confusion with another element named after Columbia University.
"Nitride" is a term used to describe a compound formed between nitrogen and another element. It is derived from the Greek word "nitron", which means "saltpeter" or "niter". The term originally referred to any compound containing nitrogen. Later, it became specifically associated with compounds in which nitrogen is in its combined form with a metal or non-metal, such as in the case of niobium nitride.
