Abstract
This application is directed to a method of manufacturing high conductive sinters of a conductive lanthanum, chromium composite oxide material in which the specific resistance is extremely reduced with a rise in temperature, and whereby an extremely superior sinter can be provided as a heat resisting conductive material. The method of manufacturing sinters in accordance with the present invention is free from the conventional disadvantages of manufacturing sinters with conductive composite oxides of La and Cr as major components, which serves to improve the sintering properties and qualities of the product. The sinters can be easily manufactured at a temperature as low as approximately 1,500.degree. C., which is lower than temperatures previously used.
