ABSTRACT:
This invention relates to fluoride ion-selective electrodes which employ, as the active membrane component, a ternary compound of the type M.sub.x Ln.sub.y F.sub.3-x, where M is an alkaline earth metal ion such as calcium, strontium or barium, and Ln is a lanthanide metal ion such as lanthanum, cerium, prosiodymium, neodymium, promethium, samarium and europium.
