The commonly used particle sizes of green silicon carbide (GC) for foamed ceramic panels are 800# to 2000# (micron grade); the most widely used are 800#, 1000#, 1200#, 1500#.
Core Particle Size Specifications (Foamed Ceramic Grade)
| Grit | D50 (μm) | Main Application |
|---|---|---|
| 800# | 14 ± 1 | General-purpose foamed ceramic panels, balanced strength and porosity |
| 1000#–1200# | 8–13 | High-density, high-strength foamed ceramics |
| 1500#–2000# | 5–8 | Fine-pore, ultra-light foamed ceramic panels |
Key Selection Principles
- Porosity & Strength: Finer particles (1500–2000#) yield smaller pores and higher strength; coarser particles (800–1000#) increase porosity and lower density.
- Process Matching: Align with foam stabilizer dosage, sintering temperature, and target bulk density for optimal results.
- Purity: ≥98.5% SiC, low free carbon and iron content to avoid defects.
Common Trade Names
Green silicon carbide micro powder for foamed ceramics: GC800#, GC1000#, GC1200#, GC1500#, GC2000#.
