Iridium oxide electrodes for pH measurement

摘要

Iridium oxide electrodes for pH measurement comprise a pH sensitive layer contg. oxidised Ir powder deposited on an (in)organic substrate and provided with a contact. Also claimed is the prodn. of electrodes as above by mixing Ir oxide powder with organic and/or inorganic binders and applying the mixt. as a paste onto the substrate by screen printing, or mixing Ir powder with organic and/or inorganic binders, applying the mixt. as a paste onto the substrate by screen printing, and subjecting the Ir to thermal oxidn..
