Properties of Transparent Quartz Crucibles

TOQUARTZ transparent quartz crucibles are manufactured using high-purity silica, creating laboratory vessels with exceptional performance characteristics.

Résistance aux températures élevées

Operating temperature exceeds 1100°C with minimal thermal expansion (coefficient of 0.56×10-6/°C at 25-300°C). This superior thermal shock resistance makes these crucibles ideal for rapid heating and cooling cycles common in research and testing environments.

Transparence optique

Excellent light transmission properties with 92-93% transparency in the visible spectrum (450-780nm) at 1.0mm thickness. This optical clarity allows for direct visual monitoring of reactions and processes inside the crucible, critical for optical instrument development.

Résistance chimique

Resistant to most acids, bases, and corrosive environments. Only hydrofluoric acid and hot phosphoric acid will cause significant degradation, making these crucibles suitable for a wide range of chemical reactions and analytical processes.

TOQUARTZ® Solving Challenges with Transparent Quartz Crucibles

Transparent Quartz Crucibles for Precision Laboratory Equipment

Laboratory equipment manufacturers require high-purity crucibles for integration into analytical instruments. In this application, crucibles must maintain dimensional stability, chemical inertness, and thermal resistance while offering precise optical properties. Any variations in quality can affect instrument calibration and measurement accuracy.

Principaux avantages

  • TOQUARTZ® crucibles maintain dimensional tolerance within ±0.05mm for critical instrument integration.
  • Each crucible is tested to ensure ≥92% light transmission at 550nm for optical path consistency.
  • Wall thickness variation is controlled within 0.03mm across production batches to ensure calibration repeatability.
Trouver ma solution

Solution TOQUARTZ

A German analytical instrument OEM reported calibration drift due to inconsistent crucible wall thickness, causing ±0.2mm deviation in optical alignment.

TOQUARTZ® supplied crucibles with certified ±0.05mm tolerance and ≤0.03mm wall deviation, restoring calibration stability and reducing instrument rejection rate by 87%.

Transparent Quartz Crucibles for Academic Research Applications

Trace metal contamination in crucibles (e.g., Fe, Al, Na) can interfere with sensitive spectroscopic or catalytic experiments, leading to false positives or irreproducible results in peer-reviewed research.

Principaux avantages

  • TOQUARTZ® crucibles are batch-tested with ICP-MS to ensure Fe content ≤1.5ppm for trace analysis compatibility.
  • Hydroxyl content is stabilized below 25ppm to prevent interference in high-temperature gas-phase reactions.
  • Each batch includes CoA verifying Al content ≤16ppm, suitable for organometallic and photonic research.
Trouver ma solution

Solution TOQUARTZ

A US-based university lab encountered inconsistent catalytic activity due to Fe contamination (>5ppm) from local suppliers.

TOQUARTZ® provided crucibles with ICP-MS verified Fe ≤1.5ppm and full CoA, enabling reproducible results and successful publication in ACS Catalysis.

Transparent Quartz Crucibles for High Temperature Analytical Testing

In high-temperature TGA/DSC or thermal decomposition testing (>1000°C), crucibles often deform or fracture due to thermal stress, leading to sample loss, equipment contamination, and test interruption.

Principaux avantages

  • TOQUARTZ® crucibles maintain structural integrity up to 1150°C under continuous load.
  • Ultra-low expansion coefficient minimizes stress during rapid heating cycles in analytical instruments.
  • Each crucible is annealed above 1180°C to relieve internal stress and prevent microcrack propagation.
Trouver ma solution

Solution TOQUARTZ

A Canadian testing lab reported 12% crucible failure rate during 1100°C TGA runs, causing 3–4 days/month of downtime.

TOQUARTZ® supplied annealed crucibles with verified deformation resistance at 1150°C, reducing failure rate to <1% and restoring full testing throughput.

Usage Guidelines for Transparent Quartz Crucibles

Proper handling, usage, and maintenance of transparent quartz crucibles will maximize their performance and service life. Follow these guidelines to ensure optimal results and prevent premature failure or contamination issues in laboratory and analytical applications.

Manipulation et stockage

  • Handle with clean gloves to prevent fingerprint contamination
  • Stocker dans un environnement propre et exempt de poussière
  • Avoid direct contact with abrasive surfaces
  • Use dedicated storage containers for unused crucibles
  • Keep separated from other labware to prevent scratches

Compatibilité chimique

  • Avoid hot phosphoric acid which can cause erosion
  • Alkali metals and their oxides can react at high temperatures
  • Rinse thoroughly after use with corrosive materials
  • Prevent cross-contamination by dedicated use per application

Contrôle de la température

  • Avoid rapid temperature changes exceeding 200°C/minute
  • Pre-heat large crucibles gradually to prevent thermal shock
  • Do not exceed maximum operating temperature (1100°C)
  • Allow to cool naturally after high-temperature use
  • Use appropriate thermal insulation for temperature stability

Nettoyage et entretien

  • Clean with dilute acids followed by deionized water rinse
  • For organic residues, use acetone followed by alcohol rinse
  • Avoid abrasive cleaning materials that can scratch surface
  • Air dry or use clean, low-lint tissues
  • Inspect regularly for cracks or damage before reuse

FAQ

Q: What is the maximum operating temperature for transparent quartz crucibles?

A: TOQUARTZ® transparent quartz crucibles can operate at temperatures up to 1100°C continuously. The strain point is 1100°C, the annealing point is 1180°C, and the softening point is 1630°C. For applications requiring temperatures above 1100°C, please consult with our technical team for specific recommendations.

A: TOQUARTZ® Quartz crucibles are resistant to most chemicals but are attacked by hydrofluoric acid (HF) and hot phosphoric acid. Alkali metals and their oxides can also react with quartz at high temperatures. For applications involving these substances, alternative materials should be considered.

A: Selection depends on your specific application requirements. Consider: (1) Temperature range, (2) Chemical environment, (3) Required capacity/dimensions, (4) Purity requirements, and (5) Optical properties needed. Our technical team can assist with selection based on your process parameters to ensure optimal performance.

A: Each batch undergoes comprehensive testing including: dimensional verification using precision measuring instruments, visual inspection for defects under polarized light, material composition analysis, thermal shock resistance testing, and for high-purity applications, trace element analysis using ICP-MS. Test certificates are available upon request.

A:For general cleaning, use a mild acid solution (except HF) followed by thorough rinsing with deionized water. For organic residues, clean with acetone followed by an alcohol rinse. Avoid abrasive cleaning methods that can scratch the surface. For stubborn deposits, a gentle soak in appropriate solvents is recommended rather than mechanical cleaning.
