A PROCESS FOR MAKING LANTHANUM CHROMITE DENSE PRODUCTS IN AIR AT LOW TEMPERATURE PARTICULARLY SUITABLE FOR APPLICATION IN SOLID OXIDE FUEL CELLS

摘要

The present invention provides a process for making calcium substituted lanthanum chromite dense products particularly suitable for application in solid oxide fuel cells that can be sintered to density more than 95% of theoretical density at temperatures as low as 1350°C in air. Thus, the present invention provides a process for the fabrication of dense lanthanum chromite based sintered product that finds application in the fabrication of solid oxide fuel cell power pack. This low sintering temperature help in co-sintering of the monolithic solid oxide fuel cell components and hence would be highly advantageous in the efficient fabrication of SOFC.
