 in London, Hatchett analyzed a piece of columbite
Columbite
Columbite, also called niobite, niobite-tantalite and columbate [2O6], is a black mineral group that is an ore of niobium and tantalum. It has a submetallic luster and a high density and is a niobate of iron and manganese, containing tantalate of iron. This mineral group was first found in Haddam,...

, and Hachett discovered that it contained a "new earth" which implied the existence of a new element. Hatchett called this new element columbium (Cb). On 26 November of that year he announced his discovery before the Royal Society
Royal Society
The Royal Society of London for Improving Natural Knowledge, known simply as the Royal Society, is a learned society for science, and is possibly the oldest such society in existence. Founded in November 1660, it was granted a Royal Charter by King Charles II as the "Royal Society of London"...

. The element was later rediscovered and renamed niobium (its current name).

Later in life, Hatchett quit his job as a chemist to work full time in his family's coach fabrication business.

Since 1979, the Institute of Materials, Minerals and Mining ("IOM3") (London) has given the Charles Hatchett Award yearly to a noted metallurgist. The award is given to the "author of the best paper on the science and technology of niobium and its alloys."
