In-situ synthesis of a ZrB2–based composite powder using a mechanochemical reaction for the zircon/magnesium/boron oxide/graphite system [PDF]

open access: yes, 2015
A ZrSiO4/B2O3/Mg/C system was used to synthesize a ZrB2-based composite through a high-energy ball milling process. As a result of the milling process, a mechanically induced self-sustaining reaction (MSR) was achieved in this system.
