AC9853 Alumina Crucible, Al2O3 Crucible Square, 99%, 215 mL

Alumina Crucible, Al2O3 Crucible Square, 99%, 215 mL Description

The Alumina Crucible is manufactured from 99% Al2O3 in a square format with a 215 mL capacity, making it suitable for high-temperature operations. Its tensile strength (~261 MPa) and compressive strength (~2 068 MPa) support structural integrity during thermal cycling. A thermal conductivity of 30 W/(m·K) aids in efficient heat distribution, while its operating temperature of ≤1 600 ℃ and high volume resistivity contribute to minimised electrical interference in processing applications.

Alumina Crucible, Al2O3 Crucible Square, 99%, 215 mL Packing

The crucible is secured in a foam-lined, anti-static package to mitigate mechanical shock and environmental contamination during transport. An inert wrapping material protects against moisture and particulate ingress. Storage is recommended in a dry, temperature-controlled environment. Optional custom packaging, including additional shock-absorbing inserts and precise labelling, is available to meet specialised storage and handling requirements.

Frequently Asked Questions

Q1: What quality control methods are implemented to verify the crucible's material purity?
A1: SAM utilises real-time X-ray diffraction alongside microstructural evaluations during sintering to monitor phase consistency and detect inclusions, ensuring the alumina meets a 99% purity standard.

Q2: What storage conditions are necessary to preserve the crucible’s properties?
A2: The crucible should be stored in a dry, temperature-controlled setting to prevent moisture uptake and thermal degradation. Protective packaging further reduces the risks associated with mechanical shock and contaminants.

Q3: How does the crucible manage thermal stresses during high-temperature processes?
A3: Its controlled density and optimised microstructure reduce thermal shock and material strain during rapid temperature cycles, ensuring consistent performance in high-temperature applications.

Additional Information

Alumina ceramics, particularly those comprising 99% Al2O3, are widely recognised for their chemical inertness and resilience under thermal stress. Advances in sintering technology have enabled tighter control over grain size and porosity, resulting in materials that can reliably withstand rapid temperature changes and mechanical loads. These characteristics are critical in maintaining structural integrity in high-performance thermal applications.

Understanding the processing and properties of alumina crucibles is essential in sophisticated manufacturing environments. Detailed knowledge of thermal conductivity, operating temperature, and mechanical strength aids engineers in selecting components that ensure precise thermal management, enhance process efficiency, and mitigate risks associated with material deformation or failure.
