Evaluation of a Carbide-Carbon Material (CCM) alternative to Molybdenum-Graphite

Carbide-Carbon Materials (CCM) are a family of composites of wide interest for use in HEP facilities and, thanks to their high thermal conductivity and low density, they are very promising in several fields of the industry, including thermal management applications, aerospace, nuclear energy production. However, the high production costs are limiting, so far, their application for big series productions. There are two ways, investigated within WP4, for an effective cost reduction: the first one is related to the increase of the material volume produced in each machine cycle. The second way involves a decrease of the production temperature, thus reducing the energy consumed during the cycle, as well as decreasing the consumption of elements such as moulds and electrodes. Work within WP4 is advancing in both directions and this milestone focuses on the second aspect, which concerns the identification of a CCM with lower sintering temperature than the Molybdenum-Graphite (MoGr) produced by Nanoker and used in HL-LHC secondary collimators.
