ABSTRACT:
Improved electrochemical sensors are provided through isostatic processing techniques. Improved electrochemical sensors, especially those suitable for use in metallurgical melts, having, at once, long-term stability, improved sensitivity, and improved physical properties including thermal shock resistance are provided. In accordance with a preferred embodiment, unitary bodies comprising the sensing electrolyte and a source of reference potential are fabricated through isostatic processing techniques. Methods for the preparation of these improved sensors together with methods for the improvement of sensing, especially of oxygen in metallurgical melts are also disclosed.
