A self-propagating high-temperature synthesis method for Ni-ferrite powder synthesis

Synthesis of Al2O3-ZrO2 Nanocomposite by Mechanical Activated Self-propagating High Temperature Synthesis(MASHS) and Ignited via Laser

By consideration of unique properties of composite Al2O3-ZrO2 such as high toughness, high wear resistant and relative low thermal expansion, in this study, nanocomposite of Al2O3-ZrO2 was produced by Mechanical activated Self propagating High-temperature Synthesis (MASHS) using laser beam for ignition. First Al and ZrO2 powders were mixed in the mole ratio of 1:1 and milled for 1, 3 and 6 hour...

The self-propagating high-temperature synthesis of sinterable powders

Photoluminescence studies on rare earth titanates prepared by self-propagating high temperature synthesis method.

The laser-induced luminescence studies of the rare earth titanates (R2Ti2O7) (R=La, Nd and Gd) using 355 nm radiation from an Nd:YAG laser are presented. These samples with submicron or nanometer size are prepared by the self-propagating high temperature synthesis (SHS) method and there is no known fluorescence shown by these rare earths in the visible region. Hence, the luminescence transition...

A Marco-homogenous and Micro-Heterogeneous Model for Self-propagating High Temperature Synthesis (SHS)

Recently research shows that heterogeneous model is needed to explain some complex combustion behaviors in SHS. However, more heterogeneous details be considered more difficulties will be faced. A micro-heterogeneous & macro-homogeneous model is proposed in this paper based on some previous works for this problem. Combustion compact is divided into lots of little units, which are composed of a ...

Self-propagating high-temperature synthesis for compound thermoelectrics and new criterion for combustion processing

The existing methods of synthesis of thermoelectric (TE) materials remain constrained to multi-step processes that are time and energy intensive. Here we demonstrate that essentially all compound thermoelectrics can be synthesized in a single-phase form at a minimal cost and on the timescale of seconds using a combustion process called self-propagating high-temperature synthesis. We illustrate ...
