Lanthanum chromite powder is a powdery substance usually light green in appearance, with the chemical formula LaCrO₃. It is characterised by high purity, homogeneous particles and good dispersion, and has important applications in the fields of solid oxide fuel cells, ceramic materials and catalysts.
Properties
Appearance: Lanthanum chromite powder usually appears as a light green powder, the colour is one of its important appearance characteristics, which can be used as a reference to judge its purity and quality.
Melting point: Generally above 2000℃, it has a high melting point, which makes it can still maintain a stable structure and performance under high temperature environment;
Particle size: The particle size of the powder has an important impact on its application performance, generally can be customised according to different application requirements, common nano-scale and micron-scale and other different particle size range.
High Stability: Lanthanum chromite has high chemical stability at room temperature and pressure, it is not easy to react with common chemical substances, but its chemical properties may change under specific high temperature and high pressure conditions.
Oxidising properties: chromium has a variety of oxidation states in compounds, and chromium in lanthanum-chromium oxides has a certain oxidising property, which makes the substance may play a certain role in some redox reactions.
Good heat resistance: able to withstand higher temperatures without significant decomposition or phase change, it is an excellent heat resistant material.
Applications
Solid oxide fuel cell: Lanthanum chromite As the cathode material of solid oxide fuel cell, lanthanum chromium oxide powder has good electrical conductivity and catalytic activity, which can promote the reduction reaction of oxygen and improve the performance and efficiency of fuel cell.
Ceramic materials: Lanthanum chromite can be used to prepare high-temperature ceramic materials, such as ceramic capacitors and ceramic sensors. Its high melting point and heat resistance enable the prepared ceramic materials to work stably in high temperature environment.
Catalysts: used as catalysts in some chemical reactions, such as in some organic synthesis reactions, exhaust gas treatment and other processes, can accelerate the reaction, improve the efficiency and selectivity of the reaction.
Electrothermal materials: can be used to prepare electric heating elements, such as lanthanum chromate thermoelectric ceramic materials can be used for heat treatment furnace, experimental furnace, tunnel furnace and other electric heating elements, with good stability, high temperature resistance, corrosion resistance and other advantages.
Optical materials: In the field of optics, lanthanum chromium oxide powder can be used as dopant or additive to improve the performance of optical materials, such as improving the refractive index of the material and enhancing the luminescence performance.
Coating materials: Due to its good heat resistance and chemical stability, it can be used to prepare high-temperature coating materials, which are applied in aerospace, machinery manufacturing and other fields to improve the high-temperature resistance and corrosion resistance of parts.
