Abstract
Synthesis of a ZrB2-Al2O3 in-situ composite powder by the self-propagating, high-temperature synthesis (SHS) process using oxides as raw materials has been investigated. The combustion velocity was found to be about 5 mm/s. The combustion temperature varied in the range of 2173 to 2223 K, respectively. The SHS reaction was found to be mediated through melting of aluminum and, thereby, the SHS reaction. The ignition temperature is estimated to be about 1503 K by thermal analysis. Dendrite structures were also observed during SHS processing of the composite.
