Highland Refractory’s Silicon Carbide Plate, including specialized variants like SiC Plate, Silicon Carbide Ceramic Plate, and High Temperature Silicon Carbide Plate, is built for harsh industrial environments. Key specs: refractoriness ≥2200℃ to endure ultra-high heat, cold compressive strength ≥300MPa for structural stability, thermal conductivity 80-120 W/(m·K) for efficient heat transfer, and 20+ cycles of 1500℃ water-quench resistance (no cracking). The Silicon Carbide Composite Plate adds reinforced layers for heavy-load scenarios.
It fits high-temperature kiln linings (ceramic/glass production), semiconductor thermal components, and metallurgical conveying equipment. Unlike traditional refractories, it resists corrosion and wear, extending equipment life by 50% and cutting maintenance downtime. For foreign buyers and B-end users, this means reliable performance for critical high-heat processes—solving “fast wear” and “heat instability” pain points.
Silicon carbide plates are mainly composed of silicon carbide (SiC) as the aggregate (with a content usually ≥ 80%).

Highland Refractory manufactures silicon carbide plates across oxide bonded (OBSC), nitride bonded (NBSC), and reaction bonded (RBSiC) grades for kiln furniture, aluminum smelting linings, and high-abrasion industrial equipment. With 31 years of refractory manufacturing experience, we support bulk export orders with CNC-machined custom dimensions and factory-direct pricing.
Compare RBSiC, RSIC and NSiC grades, review the complete TDS, and explore application scenarios by industry.
✓ In-House CNC Machining
Dedicated SiC grinding and cutting center for custom thickness, holes, and interlocking profiles — no third-party subcontracting.
✓ Multi-Grade Production Line
OBSC, NBSC and RBSiC produced under one roof, allowing mixed-grade orders in a single shipment for multi-zone furnace projects.
✓ Bulk Export Throughput
Production capacity supports container-load and multi-container orders for EPC and industrial equipment OEM projects.
| Export Packaging | Honeycomb crates with vibration-dampening foam interlayers protect plate edges and corners during sea freight, minimizing chip and crack risk for this brittle ceramic material. |
| Lead Time | Standard sizes and grades: 20–30 working days. Custom-machined profiles with drawings: 30–40 working days depending on complexity and order volume. |
| Shipping Terms | FOB Qingdao/Tianjin by sea freight. Air freight available for urgent sample or small-volume orders. LCL and FCL both supported. |
| Documentation | Every shipment includes commercial invoice, packing list, certificate of origin, and batch material test report (MTR). |
✓ Batch Traceability
Every shipment is traceable to its production batch, with test data records retained for after-sales reference.
✓ Application Engineering Support
Our technical team assists with grade selection based on your furnace atmosphere, thermal cycle frequency, and mechanical load conditions.
✓ Replacement for Verified Defects
Manufacturing defect claims are reviewed against the batch MTR and shipment photos, with replacement or credit arranged per the sales agreement.
