Silicon nitride tubes are ceramic thermocouple protection tubes used for melting aluminum. Silicon nitride tubes surpasses most metals high temperature capabilities and has a superior combination of creep and oxidation resistance. Additionally, its low thermal conductivity and high wear resistance make it an excellent material that can withstand the toughest of conditions in the most demanding industrial applications.
High hardness, high strength, wear resistance, corrosion resistance, high temperature resistance, good thermal diffusivity, good thermal shock resistance, low density.
