An investigation on anti-reducing effect of CaO in barium titanate based ceramic Sen Wang, Zhihui Li, Xin Liu, Huan Zhang University of Science and Technology Liaoning, Institute of Ceramic Materials, Liaoning Anshan 114051 China wsenl@yeah.net Key words：Barium titanate，Grain，Anti-reducing Abstract: Anti–reducing effect of CaO in barium titanate based ceramic materials sintered at reducing atmosphere and the structure development of the materials has been studied in this paper.The results show: Addition of CaO in barium titanate based ceramic will keep resistivity of the sample sintered at reducing atmosphere at a high level.
The resistivity of the materials increase with the increasing of CaO, and the resistivity keep in constant after the amount of CaO excess 3mol%.
In the sample with sintering aid of SiO2 and BaO-excess, introducing of CaO may improve the resistivity of the materials obviously.
Experimental The samples was made by traditionally solid phase synthesis method in this work.The barium titanate powders used as raw materials was commercial product.

Experimental investigations were conducted on a laboratory scale biofilter, containing mixture of compost and polystyrene inert particles as the filter materials.
Materials and methods Organisms and culture medium Mixed culture microorganisms, obtained from a sewage treatment plant in Petrochina Liaoyang Petrochemical Company was continuously acclimated to DCA as the carbon source with a special synthetic medium in a 250 mL flask.
Filter materials The packing material for the bed consisted of a mixture (60:40 v/v) of sieved compost (4 mm and 10mm size granules, 1:1 ratio) and limestone particles(4 mm size) and polystyrene inert particles (4 mm size).
The filter material was supported by perforated plate.

Intuitively, it is possible to think that the wear is more pronounced with increasing machining time, as occurs with some materials [6] however, as has been seen in previous work, changing the parameters cutting [1,2], this does not follow a linear evolution.
Agreements The development of this work has been funded by the Ministry of Innovation and Science (project DPI2008-06771-C04-01) and the Andalusian Government.
