TopGeneral Information
Diamond is one of the most precious gems and one of the toughest materials we know today.[1,2]
TopProduction Methods
Diamond can be produced by placing carbon under high pressure and temperature. This can also be achieved by using explosives. Vapor deposition is also possible to make diamonds and ultrasound cavition is the newest technique to create synthetic diamonds.[1,2]
