  • Syntheses of new classes of hard and superhard materials1,2,3 provide new challenges for the measurement of hardness. In the past, the criteria for such measurements were based on a careful comparison and semiquantitative appraisal of materials with respect to each other. The best example of this is the Mohs hardness scale, which categorizes materials in terms of their ability to scratch one another, with diamond at the top with a value of 10. But for materials that are purportedly harder than… CONTINUE READING
