Lanthanum strontium gallium magnesium oxide
Lanthanum strontium gallium magnesium oxide (LSGM) is a ceramic electrolyte material with high ionic conductivity. LSGM is used as an electrolyte membrane to improve SOFC performance or reduce operating temperature. The ionic conductivity of LSGM is about twice that of yttrium-stabilized zirconia (YSZ-8). This LSGM powder is ideal for use in casting, ink formulation, pelletizing and other ceramic manufacturing processes.
