Moissan went on to study fluorine chemistry in great detail, contributed to the development of the electric arc furnace and attempted to use pressure to synthesize diamonds  from the more common form of carbon.
 In 1893, Moissan began studying fragments of a meteorite found in Meteor Crater near Diablo Canyon in Arizona.
 In these fragments he discovered minute quantities of a new mineral and, after extensive research, Moissan concluded that this mineral was made of silicon carbide.
In 1905, this mineral was named moissanite, in his honor.
In 1903 Moissan was elected member of the International Atomic Weights Committee where he served until his death.
