Diesel particulate filter - Wikipedia

The second most popular filter material is silicon carbide, or SiC. It has a higher (2700 °C) melting point 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.

Quick Answer: Why Melting Point Of Diamond Is Higher …

Why does silicon carbide have a high melting point? Hence the metallic bond increases in strength and needs more energy to be broken, and so a higher melting point. Silicon has a very high melting point due to its giant covalent structure; a lot of energy is needed to break the strong covalent bonds throughout the structure.
