Diamonds also occur in meteorites, probably as a result of high pressures produced dynamically by impact (10,11). The shock or explosive mode of synthesis is a viable process for fine diamond powders of both the cubic and hexagonal (lonsdaleite) polymorphs (12) naturally or otherwise. Some diamonds in space appear to have formed by processes more closely related to the low pressure chemical vapor deposition processes described later (see... [Pg.557]

Shock-wave phenomena are important in meteorite impacts where high-pressure minerals are often formed. Small diamonds useful for lapping and polishing are made commercially by shocking graphite mixed with iron and copper. The metals cool the diamonds before they can transform back to graphite on pressure release. [Pg.327]
