What is a Diesel Particulate Filter?
If you don’t have a cordierite filter then it is most likely that yours is made from silicon carbide. This substance has a much higher melting point, so is less likely to melt during the regeneration process than cordierite. The reason that they are not as popular as

The second most popular filter material is silicon carbide (). It has a higher melting point (2700 °C) than cordierite, however it is not as stable thermally, making packaging an issue. Small SiC cores are made of single pieces, while larger cores are made in segments, which are separated by a special cement so that heat expansion of the core will be taken up by the cement, and not the package.

The structure of crystalline quartz (SiO 2 ), shown in Section 12.1 "Crystalline and Amorphous Solids" , can be viewed as being derived from the structure of silicon by inserting an oxygen atom between each pair of silicon atoms.
Wide-bandgap semiconductor - Wikipedia
Wide-bandgap semiconductors (also known as WBG semiconductors or WBGSs) are semiconductor materials which have a relatively large band gap compared to conventional semiconductors. Conventional semiconductors like silicon have a bandgap in the range of 1 - 1.5 electronvolt (eV), whereas wide-bandgap materials have bandgaps in the range of 2 - 4
SIC vs cordierite - European Exhaust and alyst | - …
Both SIC and cordierite have excellent regenerative properties, a key advantage as DPFs need to regenerate in order to keep functioning properly. This is achieved when the vehicle has been running long enough and at a high enough speed to raises the temperature of the engine, and therefore the exhaust fumes, enabling the captured soot in the DPF to be burnt off.

Silicon Carbide: a Love-Hate Relationship | EE Times
Silicon carbide (SiC) has excellent properties as a semiconductor material, especially for power conversion and control. However, SiC is extremely rare in the natural environment. As a material, it was first discovered in tiny amounts in meteorites, which is why it is also called “semiconductor material that has experienced 4.6 billion years of travel.”
