Sumario:Fe(2)O(3)-Bi(2)O(3)-B(2)O(3) (FeBiB) glasses were developed as novel pH responsive hydrophobic glasses. The influence of the glass composition on the pH sensitivity of FeBiB glasses was investigated. The pH sensitivity drastically decreased with decreasing B(2)O(3) content. A moderate amount of Fe(2)O(3) and a small amount of B(2)O(3) respectively produces bulk electronic conduction and a pH response on glass surfaces. Because the remaining components of the glass can be selected freely, this discovery could prove very useful in developing novel pH glass electrodes that are self-cleaning and resist fouling.
