The solution optionally also contains compounds of formula (III) e.g., Si(OH).sub.4 or Al(OH).sub.3, or the like, or derivatives thereof condensed via oxygen bridges. The ratio of Si atoms of formula (I) to the sum of Si and/or Al atoms of formula (III) is 1:0 to 1:3, and the total concentration of compounds (I)+(III) is 0.01 to 70 wt. %. The starting material for the method is a polymeric di-, tri-, or tetrasulfane compound made up of units having the formula: ##STR1## wherein R.sup.1 has the same meaning as in formula (I), and y=2, 3 or 4. The starting material of formula (IV) is suspended in water. The suspension is mixed at 10.degree. to 100.degree. C. with hydrogen peroxide and is then agitated at 30.degree. to 150.degree. C. until a substantially clear solution is obtained. The solution is cooled and optionally neutralized, freed from any remaining insoluble components, washed and then adjusted to the required concentration.

摘要:
A piezoelectric component includes an electromechanical transducer with two first electrodes and a second electrode. The second electrode is arranged between the two first electrodes. The transducer also includes a first main side, a second main side, opposite from the first main side, and a first longitudinal side. A first contiguous metallization layer is arranged on a first partial region of the first main side and on a partial region of the first longitudinal side adjacent to the first partial region of the first main side. Here, the partial region of the first longitudinal side is kept at a sufficient distance from a side edge facing the second main side and the partial region electrically contacts the at least two first electrodes.

摘要:
A connection arrangement having an outer conductive structure arranged at least partly or completely in a cutout of an electrical insulation layer is provided. An inner conductive structure is arranged at the bottom of the cutout on one side of the insulation layer. The inner conductive structure adjoins the outer conductive structure in a contact zone. A contact area is arranged at the outer conductive structure on the other side of the cutout. The contact zone and the contact area do not overlap. The bottom of the cutout is arranged to overlaps at least half of the contact area, to provide a step in the insulation layer at the edge of the cutout outside a main current path between the contact area and the inner conductive structure.
