AC9832 Alumina Crucible, Al2O3 Crucible Cylindrical, 99%, 330 mL

Alumina Crucible, Al2O3 Crucible Cylindrical, 99%, 330 mL Description

The alumina crucible based on Al₂O₃ with 99% purity is presented in a cylindrical form with a volume of 330 mL. The controlled density of 3.7-3.9 g/cm³ provides stable structural integrity, while tensile and compressive strengths of ~38 Kpsi and ~300 Kpsi support its use in high-temperature environments. Its measured thermal conductivity of 30 W/(m·K) aids in even heat distribution, and it operates at temperatures up to 1600 ℃ for demanding thermal processes.

Product Comparison

Alumina Crucible, Al2O3 Crucible Cylindrical, 99%, 330 mL Packing

Each alumina crucible is individually packed within an inner anti-static, cushioning wrapper and placed in a rigid, sealed container to prevent mechanical impact and contamination. The package includes moisture barrier materials and is recommended to be stored in a temperature-controlled, dry environment. Custom packaging options, such as multi-unit cartons or individual blister packs, are available to align with specific handling and transportation requirements.

Frequently Asked Questions

Q1: How does the crucible perform under extended high-temperature usage?
A1: The crucible retains its structural form and thermal conductivity when operating at temperatures up to 1600 ℃. Its controlled alumina purity and density ensure minimal thermal gradients, reducing the risk of thermal shock during prolonged high-temperature exposure.

Q2: What cleaning methods are recommended for maintaining the crucible’s surface integrity?
A2: It is advised to use high-purity, non-abrasive solvents for cleaning. Avoid mechanical scrubbing to prevent surface micro-abrasions, which could affect the crucible's performance during thermal cycling.

Q3: Can customisation be arranged for different volume or mechanical specifications?
A3: Yes, customisation options are available. Customers can request tailored dimensions or slight modifications to mechanical tolerances. SAM's R&D department provides technical consultations to adapt the crucible to specific process requirements.

Additional Information

Alumina ceramics are widely recognised for their stability and performance in high-temperature environments. Their characteristic chemical inertness and effective insulation properties make them essential in materials processing and research applications. Detailed control over sintering conditions contributes to uniform microstructure development, a critical factor in ensuring consistent thermal and mechanical performance.

Continued advances in ceramic processing techniques enhance the predictability and performance of alumina components. Researchers and engineers benefit from improved consistency in material properties, which supports the development of high-temperature reactors, furnaces, and laboratory instruments requiring precise thermal management.
