<p>The piezo-ceramics (46) has a crystal structure (40) formed from a base material. An intracrystalline breaking mode is produced by increasing intergranular strength by forming an intergranular nanocomposite (49). The nanocomposite is formed by applying an inert nanoparticle (48) made of platinum, magnesium oxide and silicon carbide, in the base material before sintering and/or calcination. An amount of the nanoparticle is less such that macroscopic material- and electromechanical characteristics of the piezo-ceramics does not differ from the other piezo-ceramics made of the base material. An independent claim is also included for a piezo-injector including a holding body.</p> |
