Patent ID: 7727425

Claim:
A method for manufacturing a high-energy, low-voltage ignition plug comprising a ceramic material between its electrodes, comprising the steps of: forming an admixture by mixing in a container containing a liquid, from 50 to 75% by mass of a compound which forms a conductive phase and from 25 to 50% by mass of one or more materials which allow the formation of insulating phases of yttrium garnet after thermal processing; pulverising, drying and sieving the admixture; pressing or injecting the admixture into a mould; carrying out sintering of the admixture so as to obtain a ceramic material having porosity of between 0 and 30%, the sintering of the admixture being carried out under a controlled argon atmosphere; and using the ceramic material in order to constitute a material located between the electrodes of a high-energy, low-voltage ignition plug.
