Quartz Crucibles Features:

1. Ultra-High Temperature Resistance

• Withstands temperatures above 1600°C (short-term up to 1750°C), ideal for extreme melting processes.

• Excellent thermal shock resistance for rapid heating/cooling cycles.

2. Superior Chemical Inertness

• Resistant to most acids (except HF and hot H₃PO₄), molten salts, and metal melts.

• Non-contaminating for high-purity applications like semiconductor manufacturing.

3. High Purity & Low Thermal Expansion

• Made from 99.99% pure quartz, minimizing impurity transfer.

• Ultra-low CTE (~0.5×10⁻⁶/°C) ensures dimensional stability at high temperatures.

4. Optimized Thermal Performance

• Better thermal conductivity than ceramic crucibles for uniform heating.

• High mechanical strength prevents deformation during prolonged use.

5. Optical Transparency (Optional)

• Some variants offer UV-NIR transparency for real-time process monitoring.

Quartz Crucibles Applications:

1. Monocrystalline Silicon Growth (PV/Semiconductor)

Essential for Czochralski (CZ) method to produce ultra-pure silicon ingots.

2. Precision Alloy Melting

• Melts reactive metals (e.g., titanium, platinum group) without carbon contamination.

3. High-Temp Chemical Analysis

• Used in XRF, ICP-MS sample fusion for accurate elemental testing.

4. Advanced Glass & Ceramics

• Synthesizes optical glass, laser crystals, and high-melting-point ceramics.

5. Cutting-Edge Material Research

• Provides clean environments for graphene growth, perovskite synthesis, etc.
