    摘要： The invention relates to a nonlinear electrical material with improved microvaristor filler (1′), to devices and electrical apparatuses comprising such nonlinear electrical material and to a production method thereof. According to invention, the filler (1′) comprises larger spherical particles (5) and smaller irregular particles (6) that are arranged interstitially and provide non-point-like and/or multiple contact areas (56, 56a, 56b, 66) owing to their irregular outer shape comprising edges and faces. Embodiments, among other things, relate to: spherical particles (5) being calcinated and broken-up to retain their original shape; irregular, spikly shaped, particles (6) obtained by calcinating or sintering and crushing or fracturing granules or blocks; and addition of a third filler fraction. Advantages, among others, are: higher filler contents, more and more durable inter-particle contacts (56, 56a, 56b, 66), enlarged effective micro-contact area, and improved electrical performance of the nonlinear electrical material.

    摘要： The manufacturing method for an electroceramic component (1), for example a varistor (1), comprises a laser irradiation of a part (5; 6) of the surface of an electroceramic body (2) before a metallization (3; 4) is applied to the part (5; 6) of the surface. By means of the laser irradiation it is possible to produce a micro-roughness and/or a chemical modification of the surface which permits good adhesion of the metallization, and it is possible to reduce or eliminate areas of unevenness or waviness of that part (5; 6) of the surface of the electroceramic body (2) which is to be metallized. In addition, improved transverse conductivity can be produced, by virtue of which a low contact resistance and a very homogeneous current distribution is achieved, in particular near to the metallization (3; 4). In addition it is possible to remove residues which originate in particular from a sinter support or from the application of a passivation layer. After the laser irradiation, the electroceramic body advantageously has a border (9) which adjoins the part (5; 6) of the surface and which is not laser-irradiated. The laser beam can advantageously be pulsed and focused.

    摘要： The disclosure relates to an overvoltage protection means containing ZnO microvaristor particles for protecting electrical elements and a method to produce the means. Single microvaristor particles are placed in an arrangement having a monolayer thickness and are electrically coupled to the electrical element to protect it against overvoltages. Embodiments, among other things, relate to: 1-dimensional or 2-dimensional arrangements of microvaristor particles; placement of single microvaristors on a carrier; the carrier being planar or string-like, being structured, being a sticky tape, having fixation means for fixing the microvaristors, or having electrical coupling means. The monolayered overvoltage protection means allows very tight integration and high flexibility in shaping and adapting it to the electric or electronic element. Furthermore, reduced capacitance and hence reaction times of overvoltage protection are achieved.
