An electrically heated spray nozzle comprising a ceramic pin is described, the ceramic pin comprises a flow channel having at least one opening for a fluid to be atomized, wherein the ceramic pin includes a ceramic inner conductor and a ceramic outer conductor, between which a ceramic insulator is disposed.

Electrically heated spray nozzle

Composite conductor comprising a metallic conductor and a ceramic conductor or non-conductor, at least one of them being elongate, the two being connected with each other in an electrically conductive manner. The ceramic conductor or non-conductor and the metallic conductor are hard-soldered to each other by a contact surface extending obliquely to the longitudinal direction of the at least one elongate conductor, and has one of the conductors tapers at its end and the other conductor has a matching tapering recess. The tapering end of the conductor is fitted into the tapering recess.

Composite conductor, in particular for glow plugs for diesel engines

The invention describes a spark plug having an outer electrode (), a central electrode (), an inner conductor () connected to the central electrode () and an insulator () enclosing the inner conductor (). It is provided according to the invention that the insulator () is produced by extrusion. The invention further relates to a method for production of a spark plug of that kind.

Spark plug and method for production of a spark plug

A method for manufacturing a ceramic glow pin which is formed of more than two layers arranged especially coaxially to the axis of the glow pin and symmetrically. The layers of the layer structure are manufactured by co-extrusion.

Si.sub.3 N.sub.4 -based sintered compositions containing MgO and optionally other sintering additives, which after sintering, has a flexural strength level at room temperatures of .gtoreq.800 MPa, measured by the four-point bending method, and a Weibull modulus of &gt;15, is produced by mixing MgO, any additional sintering additives and Si.sub.3 N.sub.4 powder to form a mixture, calcining the mixture in an oxygen-free atmosphere to obtain a pre-synthesis mixture, and adding the pre-synthesis mixture to uncalcined Si.sub.3 N.sub.4 powder which is then sintered.
