Scientific Research & Laboratory
High-purity fused quartz, sapphire, and specialty ceramic components for university research, national laboratory, and advanced R&D applications requiring the highest material purity.
Fused Quartz & Advanced Ceramics for Scientific Research
Research laboratories and national facilities frequently require components that exceed the specifications of commercial semiconductor production — either in purity, dimensional precision, exotic geometry, or material performance at extremes of temperature, radiation, or chemical environment.
Tuguan Semiconductor supplies prototype and small-batch precision components directly to academic, government, and industrial research laboratories worldwide.
Typical Research Applications
Ultra-High Vacuum (UHV) Chambers
Fused quartz and synthetic silica are among the few materials suitable for UHV service:
- Outgassing rate < 10⁻¹⁰ mbar·L/(s·cm²) after 150°C bakeout
- He leak rate of welded assemblies < 1×10⁻¹⁰ mbar·L/s
- No virtual leaks from absorbed water in grain boundaries (single-material, no bonded joints)
High-Temperature Reaction Tubes (> 1200°C)
Research furnaces often operate at temperatures beyond commercial semiconductor requirements. Options by temperature range:
| Temperature Range | Material | Form |
|---|---|---|
| Up to 1200°C | Fused quartz Grade 1 | Tube, boat, crucible |
| Up to 1700°C | Al₂O₃ 99.9% | Tube, boat, crucible |
| Up to 2000°C | Boron nitride (inert atm.) | Crucible, liner, nozzle |
| Up to 2200°C | Silicon carbide (sintered) | Tube, susceptor |
Crystal Growth Equipment
Czochralski and Bridgman crystal growth systems require:
- Quartz crucibles (for silicon Czochralski growth)
- Quartz or alumina growth tubes
- BN or SiC susceptors for RF-heated systems
All crystal growth crucibles are manufactured to the highest purity (Grade 2 synthetic silica for Si crystal growth) and inspected for inclusions, bubbles, and wall uniformity.
Neutron & X-ray Beamline Components
Fused quartz and synthetic silica have very low neutron capture cross-sections, making them ideal for beamline windows, sample holders, and flow cells in neutron scattering experiments.
| Component | Material | Property Required |
|---|---|---|
| Neutron window | Synthetic fused silica | Low neutron capture; high purity |
| X-ray capillary | Fused quartz | Thin wall (0.01–0.1 mm); transparency to X-ray |
| Sample cell | Fused quartz | Chemical resistance; optical transparency |
| Cryostat window | Sapphire | Low-temperature IR transparency |
Plasma Physics Equipment
Research plasma chambers (tokamaks, helicons, RF sources) require:
- UHV-compatible quartz viewing ports
- High-purity quartz and ceramic insulators
- Sapphire viewports for high-power plasma facing surfaces
Prototype & Small-Batch Service
Research applications typically require:
- 1–10 pieces per order — we accept prototype quantities
- Complex geometries — machined from customer drawings
- Short lead times — 5–10 days for moderate complexity
- Technical consultation — application engineers available to advise on material selection and design
