In industries like metallurgy, non-ferrous smelting, and ceramic manufacturing, the choice of refractory material directly impacts production efficiency, equipment lifespan, and operational safety. Among the top performers in this space, silicon nitride-bonded silicon carbide (Si₃N₄-SiC) brick stands out—not just as a technical solution but as a proven, globally trusted standard.
| Property | Typical Value | Industry Benchmark |
|---|---|---|
| Cold Crushing Strength | ≥ 120 MPa | Standard SiC bricks: ~80 MPa |
| Thermal Conductivity | ~35 W/m·K | Alumina-based bricks: ~20 W/m·K |
| 抗热震性 (ΔT = 1100°C) | ≥ 30 cycles | Conventional bricks: ≤15 cycles |
| Corrosion Resistance | Excellent vs. molten metals & slag | Proven in real-world tests at European foundries |
These figures aren’t just numbers—they represent measurable improvements in uptime, reduced maintenance costs, and higher throughput. For example, one major copper smelter in Germany reported a 30% increase in lining life after switching to Si₃N₄-SiC bricks, with no loss in thermal efficiency or structural integrity.
This isn’t just a local success story—it’s a global one. Over 80% of our production is exported to North America, Europe, and Southeast Asia, where it’s used by companies such as ThyssenKrupp, Rio Tinto, and several Tier-1 ceramic manufacturers. The product has passed rigorous quality audits from ISO 9001 and ASTM C271 standards, giving buyers confidence in performance consistency across batches.
Whether you're operating a high-temperature furnace in a steel plant or managing kiln linings in advanced ceramics, this brick delivers what matters most: reliability under extreme conditions.
Let your equipment run longer, operate more stably, and reduce unplanned downtime.
If you’re evaluating refractory solutions for critical applications, don’t rely on generic options. The data speaks clearly—Si₃N₄-SiC brick is engineered for performance that meets the demands of modern industrial processes worldwide.
