Main Characteristics :
Maximum service temperature is 1,450°C, and especially suitable at the long time firing beween 1,200~1,450°C range. N-SiC is made by SiC bonded by Silicon Nitride (Si3N4) chemically stable, suitable to apply firing products need to avoid oxidation reaction.
It is a class higher SiC refractory compare to Oxide Bonded SiC, in terms of oxidation resistance, thermal shock resistance and strength. Used as plate, beam and for refractory for molten aluminum etc
