{"product_id":"citsofeceslscfgdc","title":"LSCF\/GDC (68 wt%) Electrode Slurry for Intermediate Temperature SOFC\/SOEC, 100 g\/bottle, CITSOFECESLSCFGDC","description":"\u003cp\u003eIn the production of Solid Oxide Fuel Cells (SOFC) and Electrolysis Cells (SOEC), an LSCF\/GDC composite slurry is the industry-standard \"ink\" used to deposit the oxygen electrode. Since LSCF is a Mixed Ionic-Electronic Conductor (MIEC) and GDC is a high-performance ionic conductor, this composite maximizes the surface area available for the electrochemical reaction.\u003c\/p\u003e\n\u003cp\u003eMixing LSCF (La0.6Sr0.4Co0.2Fe0.8O3-x) with GDC (Ce0.9Gd0.1O1.95) in a slurry provides three critical advantages: (1) \u003cstrong\u003e3D Reaction Zone\u003c\/strong\u003e: While pure LSCF can conduct ions, its ionic conductivity is much lower than GDC. Adding GDC particles creates \"ionic highways\" that extend the reaction site from the electrolyte interface deep into the electrode bulk. \u003cbr\u003e(2) \u003cstrong\u003eThermal Expansion Coefficient (TEC) Matching\u003c\/strong\u003e: Pure LSCF has a high TEC (~15 * 10^{-6} K^{-1}). Mixing it with GDC (~12 * 10^{-6} K^{-1}) brings the composite closer to the YSZ electrolyte (~10.5 * 10^{-6} K^{-1}), preventing the electrode from peeling off during thermal cycling. (3) \u003cstrong\u003eSintering Control\u003c\/strong\u003e: GDC particles act as \"spacers\" that prevent LSCF grains from over-sintering and losing porosity at operating temperatures.\u003c\/p\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv style=\"text-align: start;\"\u003e\n\u003cp\u003eA high-performance screen-printing ink typically follows this mass distribution:\u003c\/p\u003e\n\u003cp\u003e\u003cimg style=\"float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0774\/6591\/1526\/files\/CITSOFECESLSCFGDC_02_240x240.png?v=1773815468\"\u003e\u003c\/p\u003e\n\u003cp\u003eWhen using an LSCF\/GDC slurry, it is necessary to apply it over a dense GDC Barrier Layer if the electrolyte is YSZ. (1) Problem: During the 1000°C–1100 °C sintering of the LSCF slurry, Strontium (Sr) will migrate into a YSZ electrolyte and form Strontium Zirconate (SrZrO3), an insulator that significantly increases the cell's ASR (Area Specific Resistance). (2) \u003cstrong\u003eSolution\u003c\/strong\u003e: A thin (2-}5 um) dense GDC layer acts as a chemical buffer, blocking the Sr migration while allowing oxygen ions to flow.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ctable width=\"100%\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePart Number\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003eCITSOFECESLSCFGDC (C-SOFEC-ES-LSCFGDC)\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003eActive Material\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/echemsupplies.com\/products\/citsofecceplscfgdc?variant=47455616532710\"\u003eLSCF\/GDC\u003c\/a\u003e (50 wt% : 50wt%)\u003c\/p\u003e\n\u003cp\u003eSolid state content: 68 wt%\u003csub\u003e\u003c\/sub\u003e\u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003cp\u003e100 g\/bottle (other grades, such as 500 g, and 1000 g or larger can be supplied upon request)\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\/S037877531001918X\"\u003eM.
