This book provides a comprehensive overview of all the major superhard materials such as polycrystalline, single crystal diamond, and boron nitride. The authors discuss properties of these materials, and explore both current and emerging uses, in a range of industries. Both abrasive and non-abrasive applications are covered, including thermal, optical, and electronic. The book discusses how superhard materials can be best utilized in current and future applications. It compares and contrasts superhard materials, exploring the appropriate selection of the distinct superhard material for each type of application. The authors explain in in detail about when and how to make the transition to a superhard solution and explore the changes in requirements that are the driving force behind the creation and modification of superhard materials. Materials scientists and engineers from the electronic, electrical, mechanical and optical disciplines will find this work valuable. Its appeal lies in the collation of both current research knowledge of the materials and the latest relevant requirements and solutions from industry.
