FF 03 02 02 "Intermetallic Fibre Materials for Hot Gas Filtration in Power Plants and Combustion Plants" by Simon Steigert, Zi Li, GKN Sinter Metals Filters GmbH (DE), Olaf Andersen and Günter Stephani, FHG IFAM Dresden (DE), and Theo Schrooten, INTENSIV-FILTER GmbH & Co. KG (DE), 7 p.
In this BMBF sponsored project a high temperature resistant intermetallic filter for hot gas filtration was successfully developed. As base material for the filter element, melt extracted Ni3A1 short fibers were used. The authors believe there is a great potential for porous materials based on Ni3A1. It is possible to design filters with specialized geometry, porosity and filter grade. The intermetallic alloys have the potential for use at temperatures above 800°C in severe environments. High temperature filtration increases the efficiency of many industrial processes. In some processes a costly  cooling step for the waste medium could be avoided by using filters that are resistant to high temperatures and thermal shock. Porosity, filter grade and geometry can be widely adjusted with these fibers and the kind of production process.
