Applications Of RBSC

Applications Of RBSC

Kiln Furniture And Support Components
The high temperature strength, oxidation resistance and thermal shock resistance of RBSC enable manufacturers to produce low mass kiln supports compared to conventional kiln furniture materials such as cordierite. Kiln products include thin walled beams, posts, setters, burner nozzles and rolls. The components lower the thermal mass of kiln cars, result in energy savings and provide the possibility for faster product throughput. However, there a furnace support made from RBSC would be typically about four times more expensive than cordierite.
Wear Parts And Thrust Bearings
Vacuum furnace good wear resistance, high temperature strength and corrosion resistance make RBSC an ideal material for wear components, such as screws, plates and impellers. It can also be used in thrust bearings that can carry extremely high loads in heavily contaminated liquids. The properties enable the production of compact bearings capable of operating in the temperature range -200°C and 400°C.
Mechanical Seals And Vanes
RBSC has been successfully used in mechanical seals and pump vanes with high abrasion resistance. Careful control of the free graphite level within the final body determines the material properties. RBSC with free graphite is used as a seal nose material contacting hardfaces in hostile operating environments.
Precision Components
The negligible volume change after reacting with liquid silicon means that components can be formed with complex shapes and to exacting tolerances. Examples of components made by this route include laser mirror blanks, wafer handling devices and optical benches. The components are lightweight and stiff with excellent thermal stability.
