摘要
Silicon nitride (Si3N4) is a good candidate for a DPF substrate due to its excellent mechanical and thermal properties. A new process for producing porous silicon nitride is established and fundamental characteristics of fabricated silicon nitride honeycomb is evaluated, including mechanical properties and chemical stability against CeO2 ash as well as pressure drop and soot regeneration behavior.
