Graphite crucibles, heaters, shields, susceptors, insulation, and coated components for SiC Physical Vapor Transport (PVT) crystal growth programs.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Hot-Zone BOM Coverage | Crucible, lid, liner, heater, shield, susceptor, and felt | PVT performance depends on the complete thermal-field stack, not one isolated part. |
| Purity Target | < 10ppm; < 5ppm reviewed by application | Low ash and controlled impurities reduce contamination risk during high-temperature sublimation growth. |
Decision fit
SiC wafer manufacturers, PVT furnace operators, and crystal growth laboratories qualifying high-purity graphite consumables.
Primary proof point
Crucible, lid, liner, heater, shield, susceptor, and felt
PVT performance depends on the complete thermal-field stack, not one isolated part.
RFQ trigger
| Decision Gate | What Buyers Should Check | Acceptance Evidence |
|---|---|---|
| Use-case fit | 4H-SiC and 6H-SiC PVT growth; 6-inch and 8-inch boule development; Replacement consumables for crystal growth furnaces and pilot lines | Application, furnace duty, and buyer-side validation goal are confirmed before material or process route selection. |
| Parameter baseline | Hot-Zone BOM Coverage: Crucible, lid, liner, heater, shield, susceptor, and felt; Purity Target: < 10ppm; < 5ppm reviewed by application | Target ranges, report needs, and pass/fail criteria are written into the RFQ or sample approval plan. |
| Risk closure | Supply chain interruption: Use annual forecast, replacement-cycle planning, and safety stock discussion after sample validation.; Thermal-field mismatch: Review the complete furnace interface and component stack before quoting isolated replacement parts. | Drawing notes, inspection scope, cleaning, coating, packaging, and traceability controls are agreed before repeat supply. |
| RFQ completeness | Furnace type, boule size target, and current hot-zone architecture; Drawings for crucible, lid, liner, sleeve, heater, shield, or support parts; Graphite grade, density, ash, impurity, coating, and insulation requirements; Observed wear, cracking, contamination, or yield issues in current parts | Engineering can return a quote direction without avoidable loops for drawing, purity, coating, quantity, or delivery gaps. |
Map the current furnace architecture, consumable wear pattern, purity risk, and replacement schedule.
Select crucibles, heaters, susceptors, insulation, shields, and support parts that match the thermal-field duty.
Define sample quantities, acceptance evidence, inspection reports, and qualification steps before recurring supply.
Plan batch traceability, annual forecast, packaging controls, and shipment windows for repeat consumables.
Compare crucibles, heaters, susceptors, felt insulation, and machined graphite parts.
Review ash and impurity controls for contamination-sensitive furnace consumables.
Prepare custom OEM parts when standard geometry cannot match the furnace interface.

Yes. We can review crucibles, lids, liners, heaters, shields, susceptors, rings, and graphite felt insulation as one RFQ package when drawings are available.
Yes. After sample approval, we align revision control, inspection evidence, packaging, annual forecast, and delivery planning for repeat furnace consumables.
