Russian and Ukrainian scientists have created new super hard material based on impact diamonds

27 october 2014
Siberian and Ukrainian scientists have created new super hard material based on impact diamonds, that will significantly improve working lifespan of cutting and drilling equipment, TASS agency reported.
Experts managed to create sintered diamond materials, formed of small-size grains at high pressure and temperatures up to 1,800,000 degrees C. In the process of creation sintered cakes can be shaped as cutting blades, drill core, etc. Impact diamonds sinters turned out to have unique characteristics.
They provide 40-50% improvement of processing super-hard materials as compared to usual diamond sintered materials.
Impact diamonds are more robust than traditional kimberlite diamonds and the only place on the Earth they can be found at is Popigai crater in Yakutia. The deposit was formed about 35 mln years ago as a result the shock produced by asteroid hitting the Earth.
