Technical SpecificationsKiribati, a sovereign archipelagic nation in the central Pacific Ocean, presents a unique set of operating conditions for heavy machinery, civil engineering projects, and industrial systems. Comprising 32 atolls and one raised coral island (Banaba), Kiribati's economic and physical infrastructure is intricately linked to the marine environment. The predominant industrial activities in the region center on marine dredging for land reclamation, port operations in Tarawa, coral aggregate processing, and the maintenance of critical freshwater generation infrastructure, particularly desalination plants.
In these operations, equipment components face a combination of destructive forces: high-velocity slurry abrasion, solid particulate impact, and relentless electrochemical corrosion caused by saltwater. Standard wear materials, such as structural steel or hardened alloys, rapidly fail under these combined actions. The introduction of Steel-Backed Silicon Carbide (SiC) Ceramic Wear Liners marks a major technological advancement for the region. By combining the extreme hardness of silicon carbide tiles with the impact-absorbing properties of a vulcanized rubber matrix and the structural support of steel plates, industrial operators in Kiribati can achieve unprecedented equipment service lifetimes.
Historically, mining of phosphate resources on Banaba Island was the primary economic driver. Today, the focus has shifted toward building resilient infrastructure to mitigate environmental challenges. Tarawa's modern ports handle vast shipments of incoming dry goods, construction aggregates, and fuel. Conveyor transfer chutes, hopper bins, and discharge launders at these terminals are constantly bombarded by abrasive aggregates. Replacing worn-out metal chutes in remote locations like Kiritimati or Tarawa incurs massive logistics costs and downtime. Deploying maintenance-free, ceramic-lined wear components ensures continuous operational capability and secures the local supply chain.
Across the global bulk handling and mining sectors, there is a clear transition from traditional alumina (Al₂O₃) ceramics to high-purity Silicon Carbide (SiC) formulations, particularly Reaction Bonded Silicon Carbide (RBSiC/SiSiC) and Sintered Silicon Carbide (SSiC). Silicon Carbide exhibits superior mechanical, thermal, and chemical properties that make it uniquely suited to combat wear in coastal infrastructure.
The primary advantage of Silicon Carbide lies in its extreme hardness. Operating at 9.5 on the Mohs scale (approaching diamond's hardness of 10), SiC resists scouring and micro-cutting from abrasive coral sand, crystalline quartz, and granite aggregates. In slurry pipelines where particulates impinge on pipe walls at high velocities, SiC tiles remain virtually undamaged, maintaining the flow dynamics of the system and preventing localized wall-thinning.
| Property Matrix | Silicon Carbide (RBSiC) | Alumina Ceramic (95% Al₂O₃) | Carbon Steel (Q235) | Hardox 500 Alloy Steel |
|---|---|---|---|---|
| Mohs Hardness | 9.5 | 9.0 | 5.5 | 6.5 |
| Bulk Density (g/cm³) | 3.02 - 3.15 | 3.65 - 3.75 | 7.85 | 7.85 |
| Compressive Strength (MPa) | > 2200 | > 2000 | ~ 400 | ~ 1200 |
| Fracture Toughness (MPa·m1/2) | 4.5 - 5.2 | 4.0 - 4.5 | ~ 50 | ~ 45 |
| Corrosion Resistance (Acids/Alkalis) | Excellent (Inert) | Very Good | Poor | Moderate |
In addition to raw hardness, the synergy of the composite liner design plays a critical role. While raw ceramic is brittle and susceptible to fracture under perpendicular high-impact loads, vulcanizing the SiC tiles into a dense, high-elasticity natural rubber bed allows the liner to absorb and dissipate impact energy. The steel backing plate provides structural rigidity and serves as the mounting interface, enabling secure welding or stud-bolting to host structures like chutes, hoppers, and launders. This three-in-one system prevents cracks from propagating through the ceramic layer, offering a balance of impact absorption and wear resistance.

Answers to common questions regarding the installation and performance of ceramic composite wear plates.
Coral sand slurry contains sharp, highly abrasive fragments that cause severe micro-scratching. Silicon Carbide (SiC) has a Mohs hardness of 9.5, which is harder than alumina (Mohs 9.0) and significantly harder than coral minerals. This difference in hardness prevents abrasive particles from penetrating the ceramic surface.
The vulcanized rubber layer acts as an elastic cushion. When a heavy stone or lump of aggregate impacts the liner, the rubber deforms, absorbing and dispersing the kinetic energy. This prevents the stress on the ceramic tile from exceeding its flexural strength, stopping crack propagation.
No. Our high-pressure vulcanization process uses specialized bonding agents that create a hermetic seal. This seal prevents saltwater from penetrating the interfaces between the ceramic, rubber, and steel, protecting the assembly from corrosion and delamination.
Our steel-backed composite liners can be supplied with welded stud bolts on the back plate, allowing them to be bolted directly through the host structure. Alternatively, the steel backing plate can be chamfered for direct plug welding onto the internal surfaces of hoppers and chutes.
Once CAD designs are confirmed, production typically takes 15 to 25 days. Shipments are packaged in seaworthy wooden crates and shipped via container ocean freight directly to Tarawa (Betio Port), with complete export documentation and installation instructions included.
