{"product_id":"csofeceplsm","title":"LSM (Lanthanum Strontium Manganite) Electrode Powder for SOFC\/SOEC, 100 or 500 g\/bottle, CSOFECEPLSM","description":"\u003cp\u003eIn both Solid Oxide Fuel Cells (SOFC) and Solid Oxide Electrolysis Cells (SOEC), LSM (Lanthanum Strontium Manganite) is the most well-characterized and established cathode (or oxygen electrode) material. While newer \"MIEC\" materials like LSCF are favored for lower temperatures, LSM remains the industry benchmark for high-temperature operations (\u0026gt;750 °C) due to its exceptional chemical compatibility with Zirconia-based electrolytes and its proven long-term structural stability.\u003c\/p\u003e\n\u003cp\u003eLSM is a perovskite oxide with the general formula La{1-x}SrxMnO3. Its performance is defined by its high electronic conductivity but relatively low ionic conductivity. (1) \u003cstrong\u003eOperating Window\u003c\/strong\u003e: Best suited for 750 °C to 1000 °C. At temperatures below 700 °C, the kinetics of the Oxygen Reduction Reaction (ORR) become too sluggish for pure LSM. (2) \u003cstrong\u003eCompatibility\u003c\/strong\u003e: LSM has a Thermal Expansion Coefficient (TEC) that matches YSZ (~10-11 * 10^{-6} K^{-1}) almost perfectly, preventing delamination during thermal cycling. (3) \u003cstrong\u003eA-Site Deficiency\u003c\/strong\u003e: Professional grade LSM powder is often prepared with a \"slight A-site deficiency\" (e.g., (La,Sr){0.95}MnO3). This prevents the formation of insulating secondary phases like La2Zr2O7 at the electrolyte interface during high-temperature sintering.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 112.999px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 40.6875px;\"\u003e\n\u003ctd style=\"width: 28.2374%; height: 40.6875px;\"\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%; height: 40.6875px;\"\u003e\n\u003cp\u003e\u003cspan\u003eCSOFECEPLSM (C-SOFEC-EP-LSM)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003eCAS\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cp\u003e\u003cspan\u003e66402-68-4\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003ePurity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cp\u003e\u003cspan\u003e≥99.5%\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003eChemical Formula\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cp\u003e\u003cspan\u003e(La\u003c\/span\u003e\u003csub\u003e0.75\u003c\/sub\u003e\u003cspan\u003eSr\u003c\/span\u003e\u003csub\u003e0.25\u003c\/sub\u003e\u003cspan\u003e)\u003c\/span\u003e\u003csub\u003e0.95\u003c\/sub\u003e\u003cspan\u003eMnO\u003c\/span\u003e\u003csub\u003e3-δ\u003c\/sub\u003e\u003csub\u003e\u003c\/sub\u003e\u003c\/p\u003e\n\u003cp\u003e\u003csub\u003eOther chemical formulas with customized ratios, such as \u003cspan\u003e(La\u003c\/span\u003e0.80\u003cspan\u003eSr\u003c\/span\u003e0.20\u003cspan\u003e)\u003c\/span\u003e0.95\u003cspan\u003eMnO\u003c\/span\u003e3-δ, can be supplied upon request. \u003c\/sub\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003ePSD (D50)\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\u003cspan\u003e0.5-2.0 um\u003c\/span\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003eXRD\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CSOFECEPLSM_02_160x160.png?v=1773628361\" alt=\"\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003eIonic Conductivity\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cp\u003e\u003cspan\u003e≥150S\/m@600℃～800℃\u003c\/span\u003e\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CSOFECEPLSM_04_160x160.png?v=1773628361\" alt=\"\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 28.2374%;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 71.4029%;\"\u003e\n\u003cp\u003e\u003cspan\u003e100 or 500 g\/bottle (other grades, such as 1000 g or larger can be supplied upon request)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eReferences\u003c\/strong\u003e:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/www.sciencedirect.com\/science\/article\/abs\/pii\/S0378775309000172\"\u003eM.
