    Abstract: A ceramic insulator for surrounding an electrode of an ignition device, such as a corona igniter or spark plug, is provided. The insulator is formed of a ceramic material including alumina in an amount of 28 to 38 wt. %, silica in an amount of 57 to 67 wt. %, and calcium oxide in an amount of 3 to 7 wt. %, based on the total weight of the ceramic material. The ceramic insulator is typically formed by firing a mixture of Kaolin, calcium carbonate, and silica, wherein the calcium carbonate acts as a flux during firing. The ceramic material has a relative permittivity of about 5.5 to 6.5 and thus improves the electrical efficiency of the ignition device. The ceramic material is also capable of withstanding temperatures of 900 to 1000° C. and has excellent thermal shock resistance, making it suitable for use in internal combustion engines.

    Abstract: A corona igniter (20) for emitting a radio frequency electric field and providing a corona discharge (24) includes a central electrode (22) at a positive voltage, a grounded metal shell (30), and an insulator (28) with an abruption (34) extending radially outward relative to the central electrode (22). The abruption (34) is typically an increase of at least 15% of a local thickness (t) of the insulator (28) over less than 25% of a nose length (el) of an insulator nose region (74). The abruption (34) is typically one flank (82) of a protrusion or a notch, and the flank (82) faces the shell (30). The abruption (34) reverses the electric field and voltage potential gradient along the insulator outer surface (32), repels charged ions away from the insulator (28), and thus prevents the formation of a conductive path between the central electrode (22) and the shell (22).
