Claim 6:
7. A method for producing a ceramic component as claimed in claim 1,
wherein the method has the following sub-steps:
providing a base ceramic material having the empirical formula CTiO3, wherein C is a main constituent of the base ceramic material comprising a third metal selected from a group of third metals comprising calcium, strontium, barium,
adding Mn2P2O7, a first dopant which contains a first metal and/or a second dopant which contains a second metal and/or a Ti-containing compound and/or an additive which comprises at least one first compound containing a fourth metal to the ceramic material, with subsequent mixing to obtain a mixture,

wherein the first metal is selected from a group of first metals comprising neodymium, praseodymium, cerium and lanthanum, the second metal is selected from a group of second metals comprising niobium, tantalum and vanadium, the third metal is selected from a group of third metals comprising calcium, strontium and barium, and the fourth metal is selected from a group of fourth metals comprising aluminum, nickel and iron,
grinding the mixture to obtain a ground mixture,
producing ceramic green sheets from the ground mixture,
applying inner electrodes to the ceramic green sheets,
stacking the ceramic green sheets to obtain a stack of green sheets,
pressing the stack of green sheets to obtain a pressed stack of green sheets,
singulating the pressed stack to obtain singulated green structural parts,
decarburizing the singulated structural parts to obtain decarburized structural parts,
sintering the decarburized structural parts to obtain sintered structural parts,
tempering the sintered structural parts to obtain ceramic base bodies,
applying metallizations to and firing metallizations on outer surfaces of the ceramic base bodies to obtain ceramic components.
