New Material Harder Than Diamond

Posted by ScuttleMonkey on from the thats-one-gem-thats-hard-to-imagine dept.

h4x0r-3l337 writes "Diamond is no longer the hardest substance known to man. Scientists have created a new material, called "aggregated diamond nanorods" by compressing carbon-60 under high heat. From the article: 'The hardness of a material is measured by its isothermal bulk modulus. Aggregated diamond nanorods have a modulus of 491 gigapascals (GPa), compared with 442 GPa for conventional diamond.'"

  1. Why are you giving us the modulus? by hopethisnickisnottak · · Score: 5, Insightful

    It is, after all, a measure of strength in compression, which is completely different from hardness.

    How about giving us figures for hardness? Like the Brinell Hardness Number or the results of the Rockwell hardness test?
