Portrait of Henri Moissan

Formula:

SiC

Colour:

Green, black, blue, colourless, green yellow, yellow

Lustre:

Vitreous

Hardness:

9½

Specific Gravity:

3.218 - 3.22

Crystal System:

Hexagonal

Name:

Named in 1905 after Ferdinand Frederick Henri Moissan (28 September 1852 – 20 February 1907), a French chemist who, after years of research of high-temperature methods and furnaces for the production of carbides and synthetic diamonds, discovered the natural occurrence in the Canyon Diablo meteorite.

Moissan was the first to isolate elemental fluorine and received the 1906 Nobel Prize in Chemistry for that.

Type Locality:

ⓘ Canyon Diablo meteorite, Meteor Crater area, Coconino County, Arizona, USA

Dimorph of:

UM1990-09-C:Si

Moissanite, found as tiny crystals in some meteorites (originally formed in star dust) and kimberlites, is a naturally occurring silicon carbide, SiC (in synthetic form a very important high-performance ceramic, more commonly known as abrasive "carborundum").

A large number of polytypes (predominantly hexagonal or rhombohedral) is known.
Most of the natural moissanite grains are 6H and 15R polytypes (Shiryaev et al., 2011).

An unusual example of rock-forming moissanite, also of kimberlitic origin, is known from Turkey (Di Pierro et al., 2003).

Compare 'UM1982-06-C:Si'.

Other InformationHide

Notes:

Concentrated sulfuric, nitric, and hydrochloric acids do not decompose it at their boiling point. Attacked by molten lead chromate. Does not burn in oxygen at 1000 C.

Health Risks:

No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.

Industrial Uses:

Natural moissanite is too rare to be exploited, but synthetic silicon carbide is produdced as an abrasive, and synthetic moissanite crystals are grown to use as a gemstone and diamond simulant.
