Self-propagating high-temperature synthesis of ZrO2 incorporated Gd2Ti2O7 pyrochlore

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

Low Temperature Synthesis of ZrO2 and CrO2

Some issues such as tunneling, leakage current and light atom penetration through the film are threatening the ultra thin SiO2 be as a good dielectric for future industrial and electronic devices. Moreover, ultra fine and pure ZrO2/CrO2 are also so important in ceramic technologies. We have demonstrated a series of experiments to synthesis ZrO2 as well as CrO2 at low temperature with using sol-...

Mechanical properties of chromium–chromium sulfide cermets fabricated by self-propagating high-temperature synthesis

Metal sulfides are widely used in a variety of applications requiring high hardness and toughness. In this study, the microstructure and mechanical properties of chromium–chromium sulfide cermets are investigated. The chromium–chromium sulfide cermet was manufactured using self-propagating high-temperature synthesis, a process where the material is created under a self-sustaining combustion rea...

Hidden Dynamics and the Origin of Pulsating Waves in Self-propagating High Temperature Synthesis

We derive the precise limit of SHS in the high activation energy scaling suggested by B.J. Matkowksy-G.I. Sivashinsky in 1978 and by A. Bayliss-B.J. Matkowksy-A.P. Aldushin in 2002. In the time-increasing case the limit coincides with the Stefan problem for supercooled water with spatially inhomogeneous coefficients. In general it is a nonlinear forward-backward parabolic equation with disconti...
