Superior Performance Where It Matters Most
Global manufacturers are upgrading to silicon nitride (Si₃N₄) ceramics to solve critical operational challenges. With 10x longer lifespan than traditional materials and unmatched resistance to molten metals, this advanced ceramic is transforming three key sectors:
1. Revolutionizing Aluminum Casting Operations
Industry Challenge:
Metal components degrade rapidly in molten aluminum (900°C+), causing:
• Frequent replacements (every 3-6 months)
• Contamination from material reactions
• $120,000+/year in maintenance costs per production line
Silicon Nitride Solutions:
A. Riser Tubes
✓ 900°C continuous operation (ISO 18515 certified)
✓ Zero reactivity with aluminum → 90% less dross buildup
✓ 18+ month service life vs. 3 months for metal tubes
Case Study: German auto parts maker reduced downtime by 400 annual hours
B. Heater/Thermocouple Protection Tubes
✓ Electrical insulation: >10¹⁴Ω·cm (ASTM D257)
✓ Thermal conductivity: 42W/mK (260% better than alumina)
✓ Non-wetting surface prevents aluminum adhesion
ROI Example: Tesla Shanghai saves $78,000/line/year
2. Solar Industry Breakthroughs
Multi-Crystalline Silicon Insulation Components:
• Electrode insulation rings
• Thermal barrier shields
• Protective sleeves
Key Advantages Over Competitors:
| Material | Lifetime | Voltage Resistance | Thermal Shock Cycles |
| Quartz Ceramic | 6 months | 15 kV/mm | 50 |
| Alumina | 2 years | 20 kV/mm | 100 |
| Si₃N₄ | 5+ years | 25 kV/mm | 500+ |
Industry Adoption: LONGi Green Energy increased component yield by 3.2% after switching
3. Steel Industry Wear Solutions
Si₃N₄ Wear Plates Outperform:
• Hardness: HV 1700 (vs. HV 1200 for tungsten carbide)
• Wear Rate: 0.03mm³/N·m (ASTM G65)
• Corrosion Resistance: Withstands acidic slag environments
Proven Results: Baowu Steel Group cut spare parts costs by 55% in hot rolling mills
