Halsic-N is a nitride-bonded silicon carbide with a microstructure that offers increased mechanical strength and greater durability than the typical materials used for firing honeycomb structures. An advancement of the Halsic-R range, it is designed to have an increased life span with enhanced refractory properties, including resistance to oxidation and thermal shock. The kiln furniture is suited to the production of catalytic converters and diesel particulate filters (DPFs).
