Reaction Bonded Silicon Carbide (RB SiC)

Wear Protection Products

silicon-carbide-reaction-bondedCalyco are mining and related industry Silicon Carbide Suppliers of Reaction Bonded SiC that provides superior wear, corrosion and shock resistance.

Reaction Bonded Silicon Carbide is a type of silicon carbide that is manufactured by a chemical reaction between a porous carbon or graphite with molten silicon. Reaction Bonded SiC resists wear and provides excellent chemical, oxidation and thermal shock resistance for mining and industry equipment.

Calyco Mining Equipment Supplies Reaction Bonded Silicon Carbide used for beams, burner tubes, wear liners, kiln shelves, thermocouple sheaths, burner nozzles at mining and other industrial facilities throughout Australia.

Key Applications:

Reaction Bonded Silicon Carbide for Kiln Furniture and Support Components
- The high temperature strength, oxidation resistance and thermal shock resistance of Reaction Bonded SiC enables the manufacturer of low mass kiln supports.  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.

Reaction Bonded Silicon Carbide for Wear Parts and Thrust Bearings
- Wear resistance, high temperature strength and corrosion resistance make Reaction Bonded SiC 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.

Reaction Bonded Silicon Carbide for Mechanical Seals and Vanes
- Reaction Bonded SiC can be used in mechanical seals and pump vanes with high abrasion resistance.

Reaction Bonded Silicon Carbide for Precision Components
- The negligible volume change after reacting with liquid silicon means that components can be formed with complex shapes and to exacting tolerances. The components are lightweight and stiff with excellent thermal stability.
