Material Notes:

ZRCI Type RSMAT-3000 is a high purity, high temperature, flexible form composed of continuous 97% alumina ceramic fibers designed for use to 1650°C (3002°F). Type RSMAT-3000 contains little shot and has a higher alumina content than any other ceramic fiber mat or blanket. Type RSMAT-3000 is lightweight, has low thermal conductivity and low heat capacity, and is immune to thermal shock. It is ideal for vacuum, reducing atmospheres and other applications where silica cannot be tolerated, such as powder metal sintering, stainless steel bright annealing and many fuel cell applications.Information provided by ZIRCAR Refractory Composites, Inc.
