Silicon Carbide for Diesel Particulate Filter Applications:Material Development and Thermal Design 2002-01-0324

Recently, SiC has been investigated and pursued as an alternative material for diesel particulate filter (DPF) applications. SiC has acceptable physical properties such as good thermal conductivity, refractoriness, and chemical durability. Materials for DPF applications require a particular mean pore size, porosity, and permeability. In addition, these material attributes must be coupled to an appropriate thermal design so that the filter can survive the extreme temperature gradients generated during the regeneration process. In this report several approaches to making porous SiC will be discussed and performance data based on material properties and thermal design will be presented.
