Production of a doped barium titanate ceramic used in the production of PTC resistors or multiple layered capacitors comprises adding a sintering aid to the starting materials and sintering at a maximum temperature

摘要

Production of a doped barium titanate ceramic comprises adding calcium borate, lead borate and/or barium titanium borate as sintering aid to the starting materials and sintering at a maximum temperature of less than 1200 deg C. Preferred Features: The sintering aid is exclusively calcium borate.
