Lanthanum Strontium Manganate LSM (Lanthanum Strontium Manganate) (Tast Grade)
Details
[structural characteristics] belongs to the perovskite type oxide, with a typical ABO-type perovskite structure, in which the site is lanthanum (La) and strontium (Sr) ions, and the B site is manganese (Mn) ions. By adjusting the doping amount x of strontium (Sr), the crystal structure, electronic structure and physical and chemical properties of the material can be changed.
[physical properties] usually black or dark gray powder solid. It has a certain conductivity, and the conductivity will change with the increase of strontium doping. It also has ferromagnetism and exhibits magnetic-related properties in a certain temperature range.
【Chemical properties】 Under the conditions of high temperature and redox atmosphere, it shows good chemical stability. However, in some specific strong acid-base environment, chemical reactions may occur, resulting in changes in structure and performance. Manganese ions in lanthanum strontium manganate have a variety of oxidation states, in different chemical environments, the oxidation state of manganese ions can change, thus affecting the chemical activity and electrical properties of the material.
[Use] 1. Solid oxide fuel cell (SOFC): It is a commonly used cathode material in SOFC. At the cathode, it can effectively catalyze the reduction reaction of oxygen, convert oxygen into oxygen ions, and promote the migration of oxygen ions to the anode through the electrolyte, while conducting electrons, so that a complete current circuit is formed inside the battery, and the performance and efficiency of the battery are improved.
2. Sensors, electronic devices, catalytic synthesis field, magnetic field, etc.
