Product Description

LanthanumStrontium Manganite Cathode Ink (LSM20)

Product Code: 6201635

The Lanthanum Strontium Manganite (LSM) Cathode Ink is made using a high-quality LSM powder to provide an excellent cathode ink. It can be used to fabricateyour own cells, and can be used to enhance contact of your solid oxide fuel cell to the test manifold.

Technical Specifications:

Formulation: (La_0.80Sr_0.20)_0.95MnO_3-x
Solids Loading: 62 - 72% by weight

Typical Use Guidelines:

This is a great inkfor making cathode catalyst layers for SOFC applications.
Stirring the ink before use is highly recommended. For best results, the inkshould be stirred with a spatula or a glass rod to achieve an even consistencyprior to use.

For making cathode catalyst layers that are well bonded to the electrolyte: The ink applied electrolyte istypically sintered at 100^oC (until it looks dry), then sintered at800°C for 1 hr, and then at 1150^oC for 1 hr.  If an anode catalyst layer is also going to be applied (which would require a much higher sintering temperature than the this cathode), then it is recommended that the anodecatalyst layer to be bonded to the electrolyte first.  Exposing thiscathode ink to sintering temperatures much higher than 1150°C would cause thedensification of the catalyst layer or decomposition of the phase and hence,low performance.  

For making electrical connections to a screen or wire: This ink istypically fired at 750°C or 850°C for 1 hour to ensure adhesion prior totesting at the desired test temperature. The adhesion obtained at lowersintering temperatures would not be as good as the adhesion obtained with thecatalyst layer that is sintered at much higher temperatures.
This ink can be used for screen printing for generating electrical connectionsfor wire attachments.
