Wear and Temperature Resistant Sintered Silicon Carbide Wear Liner
Material: Silicon carbide (SiC), a ceramic with very high hardness (Mohs ~9–9.5).
Manufacturing: Sintering process fuses SiC powder at high temperature (2000–2200°C) under pressure to form a dense, solid, wear-resistant block.
Properties:
Extreme abrasion resistance
High compressive strength (~3500 MPa)
Corrosion resistance (acids, alkalis, and molten salts)
High thermal conductivity and heat resistance
Electrical conductivity varies (depending on formulation)

Types of Installation
Tile lining – Sintered SiC tiles mounted onto steel plates with epoxy or mechanical fixing.
Pipe/Elbow lining – Cylindrical or conical inserts for pipelines.
Modular block lining – For chutes, hoppers, and high-wear zones; blocks interlock for strength.
Tip: Due to its brittleness, impact zones are often lined with ceramic-rubber composites or backed with steel.
