4 & 5 June 2019

If you have missed our workshop in Lund, you are now able to register for the workshop in Freiberg, Germany on the 4th and 5th of June 2019

Title: „BHT-Satellite Symposium: c-BN- and diamond based hard materials for metal and rock cutting – 2nd Flintstone2020 stakeholder meeting and 2nd Freiberg High Pressure Sym­posium“

Venue: ‘Alte Mensa’, Petersstraße 5, 09599 Freiberg (Germany)

Short description:

The Freiberg High-Pressure Research Centre (FHP) kindly invites delegates from industry, academia and politics to this satellite symposium of the annual BHT conference at TU Bergakademie Freiberg. The one-day symposium is focused on recent results and developments in high-pressure synthesis and industrial production of novel (super)hard materials based on c-BN and diamond, which can replace WC/Co-materials in metal and rock cutting applications, in order to reduce the use of the critical raw materials tungsten and cobalt. It will address topics on precursor-derived synthesis and sintering of (nano-scaled) cBN- and diamond-materials, but also on related new hard materials systems. The symposium will include talks and poster presentations covering topics from basic research to industrial applications including a focus on sustainability issues and economic implications.
