In a low pressure die casting apparatus, the properties of the rising pipe of sintered ceramic material for light metal melts is improved by a covering of heat-resistant material surrounding the upper part of the rising pipe.

Rising pipe for light metal melts

Ceramics having principal phases of aluminum iron titanate and mullite corresponding to the overall chemical composition:

Ceramics based on aluminum titanate, process for their production and

Slip-cast ceramic component having an internal chamfer which is optionally interrupted by an internally projecting area, obtainable by providing a slip cast blank of the ceramic component with uniform thickness and desired internal configuration wherein the volume corresponding to the internal chamfer is outwardly disposed and which is removed by external machining to arrive at the geometry of the ceramic component. The component is useful, inter alia, as a spacer ring which serves for the positioning of honeycomb-shaped catalyst blocks in exhaust gas lines.
