Abstract
Calcium di(aryl)phosphates, the aryl groups each carrying at least one carbon chain containing at least 3 carbon atoms, are used as electroactive materials in calcium electrodes. In a preferred calcium electrode, the calcium di(aryl)phosphate is calcium di(p-n-octylphenyl)phosphate which is incorporated in a membrane of polyvinyl chloride plasticized with di(p-n-octyl)-phenylphosphonate.
