    摘要: This invention relates to a method and device permitting measurement of oxygen activity in the molten pig iron slag and molten steel slag with high precision. According to the conventional method of measurement depending on the oxygen-concentration cell composed of a one-end-closed tube type solid electrolyte fixed to the tip of the probe, having a contrasting platinum electrode wound around the outer surface thereof, and located directly in the molten slag layer, positioning of the cell in the flowing slag is difficult and insufficient contact of the contrasting electrode with the slag layer is caused on account of thermal contraction of the electroyte resulting from heat of the slag, whereby errors possibly occur in measurement. Unlike the direct measurement of oxygen activity in the slag, this invention provides a method in which a specific metal whose oxygen activity equilibrates with that of the slag when brought into contact with the slag is contained in the same vessel together with the slag and oxygen activity in the specific metal is measured for indirect measurement of oxygen activity in the slag, whereby the problem resulting from insufficient contact of the solid electrolyte with the contrasting electrode can be solved and measurement of oxygen activity in the slag with high precision is ensured.

    摘要: The morphology of a coating of Ce oxyfluoride on a conductive substrate is improved by addition of yttrium, lanthanum, praseodymium and/or other rare earth metals. Whereas the pure Ce-oxycompound coating shows cracks which frequently extend throughout the entire thickness of the coating, thus exposing finite portions of the substrate to eventual corrosive attack from the environment, the improved coating including the above doping element(s) comprises a substantially impervious structure. Coatings of this nature may be employed with non-consumable anodes in molten aluminum electrowinning cells or as chemical sensors, corrosion protection and other applications.

    摘要: A device for measuring pH levels and contaminant concentration includes an electrode assembly that is electrically coupled to a control unit. The electrode assembly includes a FLUID first contact electrically coupled to a reference electrode, a second contact electrically coupled to a working electrode, and a third contact electrically coupled to a counter electrode. The working electrode may be modified to include a cysteine functionalized graphene oxide with polypyrrole nanocomposite. In operation, the control unit may apply a complex signal to the working electrode via the second contact in order to adhere and subsequently strip contaminant ions from the fluid sample to the working electrode. During this process, a current may be measured across the reference electrode and the counter electrode to measure contaminant ion concentration. The pH of the fluid sample may also be determined by a current measured across the reference electrode and the counter electrode. In some examples, the pH may be used to calibrate the measured levels of the contaminant ions.
