Silicon carbide products lines:
1. Reaction Sintered Silicon carbide (RBSIC)
2. Recrystallized Silicon Carbide ceramic (RSIC)
3. Nitride Bonded Silicon Carbide ceramic (NBSIC)
4. Sintered Silicon Carbide (SSiC)
Isopressed Silicon Carbide Protection Tubes Isopressed or carbon bonded silicon carbide protection tubes (SCI) are less porous (8%) than nitride bonded but not as dense as oxide bonded tubes. Isopressed silicon carbide tubes have a maximum service temperature of 2800°F or 1550°C. Composition - 78.2% Silicon Carbide (Black, course grained Alpha / Beta mix), 18.7% Silica, 2.1% Sodium Oxide, 1.43% Aluminum Oxide, .44% Iron Oxide. Note: Isopressed protection tubes are coated with a silicon carbide glaze to reduce open porosity and the reactive surface area of the protection tube. This glaze is used to help prolong the service life of the tube.
