Select application scenarios to review thermal architecture, material fit, contamination controls, and OEM support direction.
Each solution page is written for buyer-side decisions: what to validate first, where process contamination risk usually appears, and what design data should be included in the initial RFQ to avoid quote loops.
This table turns process intent into material architecture and validation focus. It is meant for engineering and procurement teams that need to align before sending a drawing package.
| Application | Primary Concern | Recommended Architecture | Validation Focus | Path |
|---|---|---|---|---|
| SiC PVT crystal growth | Purity, thermal gradient stability, crucible life, and insulation heat loss. | Purified isostatic graphite crucibles, graphite heaters, shields, rings, and rigid carbon felt. | Ash and trace-metal report, CTQ dimensions, hot-zone fit, and replacement-cycle data. | Open solution |
| MOCVD and epitaxy | Particle control, reactive gas resistance, wafer pocket accuracy, and coating lifetime. | CVD SiC coated susceptors, wafer carriers, dummy wafers, trays, and graphite substrates. | Coating thickness, base graphite match, wafer-contact surface finish, and post-coating dimensions. | Open solution |
| Semiconductor thermal fields | Assembly repeatability, high-purity hot-zone stability, and retrofit fit. | Graphite hot-zone parts with optional C/C structural reinforcement and controlled purity. | Assembly drawings, datum features, material grade, purity boundary, and installation clearances. | Open solution |
| Vacuum furnace hot zones | Power efficiency, thermal uniformity, heater life, and serviceable insulation. | Graphite heaters, graphite shields, rigid carbon felt, C/C fixtures, and hot-zone replacement parts. | Chamber dimensions, maximum temperature, atmosphere, ramp rate, insulation thickness, and packing risk. | Open solution |
| High-temperature load-bearing fixtures | Graphite brittleness, metal thermal mass, tray sag, fastener failure, and thermal shock. | 2D/3D C/C composite trays, plates, bolts, nuts, studs, and structural fixtures. | Load case, support spacing, thread engagement, atmosphere, cycle count, and oxidation boundary. | Open solution |
| Aluminum degassing rotors | Oxidation resistance, aggressive flux corrosion, thermal shock, and rotor lifespan. | Standard high-purity graphite, anti-oxidation treated graphite, or SiC-coated graphite based on melt conditions. | Melt temperature, degassing gas mixture, target lifespan, and pre-heating procedures. | Open solution |
