Twenty‐five years of diesel particulate filter (DPF) developments have shown that ceramic materials are well‐suited candidates to fulfill the harsh requirements of exhaust after treatment. The introduction of DPF in passenger cars in Europe in 2000 was a real breakthrough from both a scientific and a commercial point of view. Different systems and filter materials can be used as DPF; however, at the moment silicon carbide wall flow filters seem to be at advantage. There is a continual demand for cost‐effective and reliable materials and systems forced by increasing legal emission standards.

Compositions in the mixed strontium/calcium feldspar ([Sr/Ca]O. Al 2 O 3. 2SiO 2)-aluminum titanate (Al 2 O 3. TiO 2) system have been investigated as alternative materials for the diesel particulate filter (DPF) application. A key attribute of these compositions is their low coefficient of thermal expansion (CTE). Samples have been prepared with porosities of >50% having average pore sizes of between 12 and 16µm. The superior thermal shock resistance, increased resistance to ash attack, and high volumetric heat capacity of these materials, coupled with monolithic fabrication, provide certain advantages over currently available silicon carbide products. In addition, based on testing done so far aluminum titanate-based filters have demonstrated chemical durability and comparable pressure drop (both bare and catalyzed) to current, commercially available, silicon carbide products.

“…As a result, the pressure drop can increase, gradually, and in turn the temperature of the DPF can increase greatly, and this would ultimately result in the reaction of materials with DPF. Finally, DPF can experience partial thermal aging or can malfunction [4,11,12]. Alkali metals such as sodium and cesium are used as a type of The silicon carbide used to make diesel particulate filters (SiC-DPF) has a maximum temperature of use, which is not the melting point of the filter material itself but rather the eutectic melting points of the ash materials and alkali metals deposited on the filter wall.…”
