Many innovative self-propagating high-temperature synthesis (SHS) tech
niques such as filtration combustion, the centrifugal thermite process
, field activated combustion, solid-state metathesis, flame synthesis
and simultaneous SHS and densification have been developed for the syn
thesis of 'advanced materials'. A novel gas producing self-propagating
process initiated at low temperature using redox compounds and mixtur
es has been used for the preparation of fine particle oxides.
