The ceramic lined fine pipe, elbow and tapered pipe can be prepared by SHS-gravitational process. In order to get high quality of products, the combustion of aluminium-iron oxide thermite in this process must be under control. The effects of thermite filling density, hole in thermite and inclined angle of pipe on combustion rate were studied to direct to the controlling factor. It shows that the combustion rate decreases with the decrease of filling density. The thermite combusts downwards the pipe much more quickly if there are holes in the thermite. And the combustion rate increases with the increase of the inclined angle of pipe. The experiment results direct to the conclusion that the combustion of thermite is predominantly controlled by gas phase reaction, which appears due to the high temperature of the thermite combustion.

This paper researched the fabrication of perovskite synrock by self-propagating high temperature synthesis (SHS) and the characterization of the products. This synthesis process is simpler, the fabricated synrock can immobilize waste loading up to 35wt% SrO with satisfied physical properties (density>4.2g•cm-3, open porosity<0.2%, Leach rate<0.1g•m-2•d-1). The structure analyses by XRD and SEM/EDS show that the major phase is perovskite which well agrees with the design. It proves that SHS offer a suitable Sr-waste synroc which is favorable for geological disposal.

TiNi porous alloys were prepared as artificial bone by Self-propagation High-temperature Synthesis (SHS) in order to develop new bio-materials. The mixture of titanium and nickel powder was ignited under the atmosphere of argon gas. TiNi porous alloys with different microstructure were obtained by various ignition models such as preheating and heat explosion. SEM and XRD were used to analyses pore characteristics and phase structures of samples. The results show that SHS is a useful method to prepare TiNi porous alloys.
