A method for improving fixing effect of a ceramic strip heater is performed as follows. An electrode material is applied to each end of an upper surface of an alumina ceramic substrate by printing, followed by drying and sintering to form an electrode. A heating paste is applied to the upper surface of the alumina ceramic substrate by printing to connect two electrodes on both ends of the alumina ceramic substrate, followed by drying and sintering to form a heating filament. A glass paste is applied to a lower surface of the alumina ceramic substrate by printing, followed by drying and sintering to form a first glass layer. Another glass paste is applied onto the heating paste by printing, followed by drying and sintering to form a second glass layer, so as to arrive at the ceramic strip heater.

A system includes a support and at least one metallization that defines at least a first layer and a second layer. The support defines a support surface on which the first layer is arranged between the support surface and the second layer, which is made of at least 90% by weight of a precious metal. The first layer is made of transition metals and/or metals and/or semi-metals and has an ultrasonic damping effect.
