Silicon Carbide - Carbide Bonded Isopressed Carbon bonded isopressed silicon carbide tubes ( SCI) are less porous (8%) than Nitride bonded silicon carbide but not as dense as Oxide or Nitride bonded tubes. They have a maximum service temperature of 2800°F (1550°C) . Composition: 78.2.0% Silicon Carbide (Black, coarse grained Alpha / Beta mix), 18% Silica, 2.1% Sodium Oxide, 1.43% Aluminum Oxide, .44% Iron Oxide. Note 1: Protection tubes are coated with a silicon carbide glaze to reduce open porosity and reactive surface area of the protection tube. This glaze is used to help prolong the service of the tube.
