An additive for electrochemical energy storages is disclosed, wherein the additive contains at least one silicon- and alkaline earth metal-containing compound V1 which in contact with a fluorine-containing compound V2 in the energy storage forms at least one compound V3 selected from the group consisting of silicon- and fluorine-containing, lithium-free compounds V3a, alkaline earth metal- and fluorine-containing, lithium-free compounds V3b, silicon-, alkaline earth metal- and fluorine-containing, lithium-free compounds V3c and combinations thereof. Also disclosed is an electrochemical energy storage containing the additive.

An optical converter wheel, a method of producing, and a method of using are provided. The wheel includes an inorganic converter material that converts light of a first wavelength into light of a second wavelength and a converter substrate. The converter substrate has a coefficient of thermal expansion CTEof 4 to 18&#xd7;101/K in a range from 20&#xb0; C.-300&#xb0; C. and a thermal conductivity of at least 50 W/mK at 20&#xb0; C.

The method of electrochemical determination of oxygen partial pressure in ionic melts includes providing a metal/metal oxide reference electrode consisting of an electrode body made of a metal selected from the group consisting of Mo, W, Hf, Nb and Ta and alloys thereof and a layer of an oxide of that metal on the electrode body; immersing a pure platinum electrode and the metal/metal oxide reference electrode in a glass melt; measuring a potential across the metal/metal oxide reference electrode and the pure platinum electrode immersed in the glass melt to obtain a measured potential characteristic of the oxygen partial pressure in the glass melt; obtaining a calibration curve relating the potential across said reference electrode and the pure platinum electrode to the oxygen partial pressure in the glass melt as a function of temperature; and obtaining the oxygen partial pressure in the glass melt from the measured potential and the calibration curve. Either the calibration curve is obtained experimentally by immersing a Zirconium dioxide electrode in the glass melt and measuring a potential difference between the metal/metal oxide reference electrode and the Zirconium dioxide electrode at a plurality of temperatures or theoretically from thermodynamic data for the metal/metal oxide reference electrode.
