Another challenge for micro-tubular SOFCs is to develop alternative cathode materials in order to reduce cathode-electrolyte interface polarization.
Efforts have been devoted to lowering the cathode polarization resistance for YSZ-based micro-tubular SOFCs by introducing novel cathode materials to meet the demand for commercialization [8, 9].
The SrFe0.9Sb0.1O3−δ (SFSb) powder was also synthesized by auto-ignition process with the raw materials Sb2O3, Sr(NO3)2, and Fe(NO3)3·9H2O at a proper molar ratio and then calcined at 950 °C for 3 h.

The work undertaken demonstrates eventually that the serpentine pouring channel process is a good method for semi-solid rheo-die casting or rheo-forming of metallic materials, the process is simple and the slurry cost is not expensive. 1 Introduction The rheo-die casting technology of metals was proposed by Flemings and his fellows in the 70th of the 20th century, and in this process the prepared semi-solid slurry of metals was sent into the chamber of a die casting machine and cast in the liquid and solid region [1].

These critical restrictions make it considerable difficult to choose TPS materials.
Many different TPS materials have been designed to meet tough requirements.

Many synthetic polymers are just used for “short life” application, such as packaging materials, commodity products and hygienic articles, while they exhibit high stability towards most environmental conditions, thus making up a considerable part of the solid wastes [1,2].

Because of wide range of acoustic band for a variety of materials, AE also be called the stress wave emission and microseismic in geology[1].
Thus, AE technology can monitor initiation and expansion process of internal micro-fracture continuously, forecast the early or recent rupture of brittle materials caused by external load[6,7].
Many researchers try to establish the reliable experience relationship between AE and other properties of materials.
But rock is a natural material.
