Mechanochemical synthesis of ZrB2-SiC-ZrC nanocomposite powder by metallothermic reduction of zircon [PDF]
, 2013 Aluminium and magnesium were used in the M/ZrSiO4/B 2O3/C (M = Al, Mg) system to induce a mechanically induced self-sustaining reaction (MSR). Aluminium was not able to reduce the system to the desired products, and the system became amorphous after 10 h
