Products Description
Silicon Carbon (SiC) is a synthetic compound of silicon and carbon, renowned for its extreme hardness, high thermal conductivity, and electrical properties. Customized grades take this further by adjusting:
✔ Chemical composition (Si, C, Fe, Al content)
✔ Particle size distribution (nano-powders to coarse granules)
✔ Purity levels (90% to 99.9% SiC)
✔ Additives (bonding agents, dopants for specific applications)
This flexibility allows industries to fine-tune SiC for specialized needs, maximizing performance while minimizing waste.
Key Specifications of SiC
| Parameter | Standard Range | Custom Adjustments |
|---|---|---|
| SiC Purity | 70% - 99% | Up to 99.9%+ for semiconductors |
| Carbon Content | 10% - 30% | Optimized for conductivity or hardness |
| Metallic Impurities | ≤ 2% Fe, Al | Ultra-low (≤ 0.1%) for electronics |
| Particle Size | 0.5µm - 10mm | Nano-sized (50nm) for coatings |
| Bulk Density | 2.5 - 3.2 g/cm³ | Adjusted for sintering needs |
Why Use Customized Silicon Carbon?
**1. Enhanced Performance in Critical Applications
- Semiconductors need ultra-pure (99.9%+) SiC for high-efficiency power devices.
- Aerospace components require high thermal shock resistance with controlled porosity.
**2. Cost Optimization
- Reduce material waste by using precisely formulated SiC instead of over-engineered grades.
- Longer lifespan in abrasive tools means fewer replacements.
**3. Improved Process Efficiency
- Steelmaking: Tailored SiC deoxidizers speed up reactions, cutting energy use.
- Ceramics: Custom particle sizes improve sintering and reduce defects.
**4. Specialized Additives for Unique Needs
- Anti-oxidation coatings for refractories
- Conductive dopants for EV battery materials
