Synthesis, properties and application of high conductive LaCrO3-based ceramic materials

The synthesis of LaCrO₃ and LaCrO₃-based materials by the hydrothermal method and in air has been investigated. In respect to the synthesized products, the structure and a number of physical properties, such as electrical and magnetic properties, are discussed. The authors utilized the doped LaCrO₃ material as various “conducting leads” for ZrO₂-based heating elements to substitute the expensive Pt-Rh wire. The working temperature of these elements can be up to 2000–2100°C in oxidizing atmosphere.
