Product families for SiC PVT crystal growth, MOCVD epitaxy, TaC coated ultra-high-temperature hot zones, semiconductor thermal fields, vacuum furnaces, and specialty replacement parts.
Use this page as a pre-RFQ navigator: pick the product family, capture the correct engineering inputs like material purity and drawing tolerances, and move directly to sample validation criteria.
Use this table before opening a product detail page. It separates material architecture from part shape so RFQs do not start from the wrong manufacturing route.
| Material Family | Best Fit | Selection Trigger | Key RFQ Inputs | Review Path |
|---|---|---|---|---|
| High-purity graphite | SiC PVT crucibles, heaters, shields, rings, lids, and graphite hot-zone parts. | Use when thermal stability, machinability, and low ash content are the dominant requirements. | Graphite grade, density, ash target, trace-metal limits, operating temperature, and CAD tolerances. | Open detail |
| CVD SiC coated graphite | MOCVD susceptors, wafer carriers, dummy wafers, trays, and gas-facing epitaxy hardware. | Use when reactive gases, wafer contamination, carbon dusting, or coating lifetime drive the purchase. | Base graphite target, coating thickness, wafer size, pocket layout, equipment model, and surface finish. | Open detail |
| TaC coated graphite | SiC PVT crucibles, guide rings, seed supports, and ultra-high-temperature vapor-facing graphite hardware. | Use when SiC coating or purified graphite lifetime is limited by 2000C+ vapor corrosion, sublimation, or crystal-growth contamination risk. | TaC coating map, graphite substrate target, growth temperature, vapor exposure, seed or ring geometry, and trace-element acceptance limits. | Open detail |
| C/C composite | Fasteners, trays, plates, fixtures, and load-bearing furnace structures. | Use when graphite is too brittle or refractory metal creates excessive thermal mass and maintenance cost. | Load at temperature, support span, fiber architecture, thread standard, atmosphere, and cycle count. | Open detail |
| C/C composite bolts | High-temperature structural bolts, studs, and nuts for vacuum furnaces and SiC PVT reactors. | Use when molybdenum bolts embrittle or sag, or when graphite studs strip under torque tightening. | Thread size (M6–M24), length, head style, 3D weave architecture, operating temperature, and ash purity. | Open detail |
| Rigid carbon felt | Vacuum furnace insulation cylinders, rings, panels, and hot-zone heat-loss control. | Use when energy efficiency, thermal uniformity, insulation stability, and low outgassing matter. | Hot-zone dimensions, thickness, segmentation, foil or coating surface, and maximum temperature. | Open detail |
| Specialty graphite replacement | Dry pump vanes, aluminum degassing rotors, and high-temperature wear consumables. | Use when the problem is wear, self-lubrication, oxidation, sealing, or repeat MRO availability. | Sample or drawing, current failure mode, service interval, operating speed, temperature, and annual demand. | Open detail |
