ABSTRACT:
Method for manufacturing a high-energy, low-voltage ignition plug comprising a ceramic material between its electrodes:there is mixed, in a container containing a liquid, from 50 to 75% of a compound which is intended to form a conductive phase and from 25 to 50% of one or more materials which allow the formation of phases of yttrium garnet after thermal processing;operations are carried out for pulverizing, drying and sieving the admixture;the admixture is pressed or injected into a mould;sintering is carried out so as to obtain a ceramic material having porosity of between 0 and 30%;the ceramic material is used in order to constitute the material located between the electrodes of a high-energy, low-voltage ignition plug.Ignition plug manufactured in that manner.
