Abstract:
A sensor element that may include a contamination-resistant coating on at least a portion thereof. The coating may include gamma alumina and a high temperature binder such as magnesium titanate. A sensor element that may include a contamination-resistant coating on at least a portion thereof. The coating may include gamma alumina, a high temperature binder such as magnesium titanate, and boehmite alumina. A method of making a contamination-resistant sensor element that may include mixing gamma alumina and a high temperature binder such as magnesium titanate to form a mixture, applying the mixture to at least a portion of a sensor element, and temperature treating the mixture to form a contamination-resistant coating on the sensor element.
