Lanthanum Strontium Manganite (La0.7Sr0.3MnO3) Sputtering Target

Lanthanum strontium manganite (LSM or LSMO) represents an oxide ceramic characterized by the formula La1−xSrxMnO3. Moreover, the value of x specifically denotes the doping level. Commonly, LSM finds utilization as a cathode within commercial solid oxide fuel cells (SOFCs).
Particularly, strontium doping actively introduces excess holes into the valence band of lanthanum. Consequently, this raises electronic conductivity at higher operating temperatures. As a result, LSM proves suitable for SOFC cathodes. Additionally, LSM displays compatible thermal expansion with yttria-stabilized zirconia (YSZ). YSZ serves as a premier electrolyte material for SOFCs. This matching thermal behavior prevents cracking or separation between adjacent cathode and electrolyte layers during thermal cycling. Combined with maintained conductivity even at elevated temperature ranges, such traits underlie LSM's widespread employment in SOFC cathode applications seeking improved performance.
