Ultra-High-Temperature Purity Assurance
•Ash content <10 ppm, metallic impurities <5 ppm (semiconductor-grade purity), completely blocks silicon vapor erosion, reduces micro-pipe density in silicon carbide crystals by 83%.
•Gas-liquid composite coating technology constructs a “molecular shield,” improving silicon resistance by 300%.
•High-temperature purification process ensures zero contamination in the 2300℃ crystal growth environment.
Precise Thermal Field Control
| Performance | Grand-Hope Short-Fiber Hard Felt | Traditional Materials |
| Thermal Conductivity | 0.038 W/(m·K) | 0.15 W/(m·K) |
| Temperature Uniformity | ±2℃ (throughout 2300℃) | ±15℃ |
| Response Speed | Matches high-frequency electromagnetic field, millisecond-level temperature adjustment | Delayed by 3 – 5 seconds |
Graded pore structure (50 – 300μm) locks thermal energy, increases crystal growth speed by 40%, and boosts single-furnace productivity by 25% .
Energy-Saving and Longevity Exemplar
•Energy consumption drastically reduced: Thermal efficiency improved by 45%, saving 800,000 kWh per furnace annually (equivalent to reducing 630 tons of CO₂ emissions).
•Lifespan breakthrough: Thermal shock resistance >1200 cycles (ΔT = 2000℃ thermal cycling), replacement frequency reduced from once per month → once per year , annual maintenance costs reduced by 2 million CNY.
•Rigid yet flexible damage resistance: Three-dimensional fiber-reinforced structure resists electromagnetic vibration deformation, thermal shrinkage rate <0.3% at 2300℃.
Customer Case Study
A silicon carbide wafer manufacturer achieved the following results after adopting Grand-Hope Short-Fiber Hard Felt:
