Diamond exhibits many of the same properties as a typical ceramic: hardness, brittleness, low electrical conductivity, a wide band gap, etc. Understanding the limitations and benefits of diamond can be facilitated by relating it to ceramics. Why then is it not considered a ceramic? Perhaps it is because until recently, it was available only in relatively small quantities at a fairly high price.
The discovery that diamond can be synthesized by other than high-pressure, high-temperature, methods has opened up a whole new world of products that capitalize on its unique and not-so-unique properties. These products range from hard coatings for cuttings tools to high thermal conductivity substrates for chips to cold cathodes. Recent developments from a variety of companies will be reviewed.
