Pastes for Lambda Sensors

 

 

 

 

Types

  • Pt and Pt alloy pastes
  • Partial coating process on ceramic surfaces

Pastes for reaction electrode

Concept:
Increasing of reaction site by porosity and high distribution of YSZ/Pt

Properties & Merits:
The resistance is lower compared to normal pastes a thinner layer can therefore be generated.

Type: DES-P4

Viscosity of the paste can be customized

Pastes for heater and lead electrodes

Concept:
Adding ceramic amount in large volumescauses increase in resistivity, therefore pelletized Pt powder is used as an alternative for ceramics.

Properties & Merits:
The amount of ceramics can be reduced with the core shell powder. It brings a reduction of Pt usage by ca. 30% or lower resistivity depending on customers' demand.
