RFQ Checklist
- Target environment (vacuum, air, inert)
- Maximum operating temperature
- Purity requirement (e.g., < 5 ppm ash)
- Base graphite grade, drawing, and finished dimensions
- Failure mode: oxidation, permeability, contamination, or wear
Enhance graphite performance with anti-oxidation coatings, resin/metal impregnation, and ultra-high purification.
Complete RFQs are easier to review within 1-2 business days when drawings, graphite grade, quantity, and destination are included.
| Metric | Typical Range | Why It Matters |
|---|---|---|
| Ash Content (Purified) | < 5 ppm (often < 2 ppm) | Prevents metal ion contamination in semiconductor crystal growth processes. |
| Treatment compatibility | Defined by atmosphere, temperature, chemistry, and geometry | A treatment that works in one furnace or seal application can fail in another service window. |
| Permeability or porosity target | Buyer application dependent | Impregnation should be specified around sealing, lubrication, or wear needs rather than requested generically. |
Yes, we offer resin impregnation to seal the natural porosity of graphite for pump and valve wear parts.
Sometimes. The sequence depends on treatment type, dimensional tolerance, cleaning needs, and certificate requirements.
PPM targets are important, but application, grade, packing, certificate scope, and contamination sources should be reviewed together.
