6-Inch Quartz Tube Specifications and Compatible Tools

Key specs: 99.99% purity SiO2, max temp 1,400°C, OD 160–170 mm, fused silica construction. Compatible with:

Lam Research Centura P5000 (2012–2018)
Applied Materials Producer 4520 (2010–2016)
Hitachi HiCDA-600 (2014–2020)
Exclusion: Avoid part #QZ-6-2A from Saint-Gobain for Tokyo Electron LEGEND P8i systems (2019+); incompatible wall thickness causes gas leakage. Verify O-ring groove dimensions (ID 152.4 ±0.1 mm) against tool schematics.

What to Check Before Buying a Used 6-Inch Quartz Tube in 2026

Surface integrity: Use a 10x magnifier to inspect for cracks >50 µm or pits >3 per 10 cm². Reject if present.
Wall thickness: Measure at 5 axial points with a digital caliper; deviation >10% from nominal (e.g., 3.0 mm to 2.7 mm) indicates thermal stress damage.
Contamination: Run an ICP-MS test for heavy metals (e.g., Fe, Al); concentrations >10 ppb invalidate purity claims.
Thermal history: Request pyrometer logs. Tubes with >5,000 thermal cycles (heating/cooling) show accelerated devitrification.
Leak test: Perform a helium mass spectrometer leak check at 1x10⁻⁹ mbar·l/s max.

FAQ

Q: What’s the max temp rating for a 6-inch quartz tube?
A: 1,400°C continuous, but derate to 1,300°C for >24h cycles to prevent sagging.

Q: Used vs. new quartz tube: which is better for CVD?
A: New tubes offer higher purity, but used tubes with <100 thermal cycles and recent etch reports perform equivalently for standard oxidation.

Q: Can Heraeus quartz tubes replace Saint-Gobain in Lam Research tools?
A: Yes, if dimensions match (ID 152.4 mm, OD 165 mm). Cross-reference part
