ChemInform Abstract: EMF. MEASUREMENTS OF CELLS EMPLOYING METAL‐METAL OXIDE ELECTRODES IN AQUEOUS CHLORIDE AND SULFATE ELECTROLYTES AT TEMPERATURES BETWEEN 25‐250°

Abstract

Die EMK‐Messungen werden an Ketten mit chemisch beschichteten Metall‐Metalloxid‐ Elektroden (Metall: Pt, Rh, Ir, Zr) im pH‐Bereich von 1‐′12 in Abhängigkeit von Temperatur, Konzentration, Druck und Zeit durchgeführt.

Development of RuO2–TiO2 (70–30)mol% for pH measurements

“…Different oxides have been used for this purpose such as: PtO 2 [2], IrO 2 [2][3][4][5][6][7][8][9][10], RuO 2 [2,[11][12][13][14], Molybdenum bronzes [15], OsO 2 [2], Ta 2 O 5 [2], TiO 2 [2], PdO [2], SnO 2 [2], ZrO 2 [2], Co 2 O 3 [16], Nb 2 O 5 , WO 3 [17], PbO 2 [18]. Among the mentioned materials, the most widely promising are RuO 2 and IrO 2 due to its chemical stability and high conductivity which inhibit the space charge accumulation.…”
