| Summary: | Highly porous ceramic materials with open porosity are perspective for manufacture of the biosensors. Those materials are used as a framework and open porosity allows to inject a necessary functional components into internal volume. Electroconductive highly porous ceramics on a base of La1-xCaxMnO3 with variable composition have acceptable hardness and relatively low sintering temperature (about 1450°C). In recent work samples of highly porous ceramic with the composition of La1-xCaxMnO3 (x=0.3, 0.5 and 0.7) were obtained by impregnating a carbon nonwoven material with a slip containing pre-synthesized compounds of the desired composition, followed by annealing at 1415-1450îÑ. Obtained materials according to the scanning electron microscopy data have a pore size of up to 100 µm. The conductivity is 0.5-2.5 S/cm. |
