Stanford Advanced Materials (SAM) provides pyrolytic graphite crucible of coated and whole types. We can supply 1~200ml crucibles for whole pyrolytic graphite material and larger sizes are available for coated products. The largest available size for PG coated products can be 350mm*600mm.
Our pyrolytic graphite (PG) crucibles represent the pinnacle of high-temperature containment solutions, engineered for the most demanding metallurgical and semiconductor applications. Manufactured through advanced chemical vapor deposition (CVD) technology, these crucibles deliver unmatched purity and performance in high-value material processing.
1. Ultra-High Purity Construction
CVD process using 99.999% pure methane feedstock
Total impurities <10ppm (vs. 100-500ppm in conventional graphite)
Ideal for semiconductor crystal growth and high-purity metal evaporation
2. Superior Thermal Performance
Continuous operation up to 2300°C (in inert/vacuum)
Thermal conductivity: 400-1500 W/m·K (anisotropic)
Exceptional thermal shock resistance (ΔT >1500°C)
3. Advanced Material Properties
Bulk density: 2.10-2.23 g/cm³
Flexural strength: 70-120 MPa
Near-zero porosity (<0.5% vs. 10-15% in standard graphite)
4. Custom Engineering Options
Available as pure CVD or graphite-substrate coated versions
Standard wall thickness: 1mm (custom 0.5-5mm available)
Optional silicon carbide coating for enhanced oxidation resistance
