Frequently Asked Questions

Q1: How does the measured density influence the crucible's performance?
A1: The density range of 3.7-3.9 g/cm³ contributes to the crucible’s mechanical stability and thermal behaviour. This ensures that the crucible maintains its shape and performs predictably under high temperature and load conditions, which is critical during prolonged industrial processing.

Q2: What specific quality control measures are implemented during production?
A2: SAM incorporates thermal shock testing and compressive strength evaluations to verify that each crucible meets the specified material characteristics. These controlled tests help confirm the 95% purity and uniform microstructure required for consistent performance in high-temperature environments.

Q3: What are the recommended storage conditions for this crucible?
A3: It should be stored in a clean, dry environment with controlled temperature and low humidity. These conditions minimise the risk of contamination and microcracking, thereby preserving its structural integrity and thermal properties over time.

Additional Information

Alumina (Al2O3) ceramics are extensively utilised in environments demanding high thermal resistance and chemical inertness. Their intrinsic properties, including high compressive strength and excellent electrical insulation, make alumina an essential material in high-temperature and chemically aggressive settings.

In research and industrial applications, alumina is valued for its ability to maintain dimensional stability under thermal cycling. Understanding the processing techniques and microstructural characteristics further highlights the relevance of alumina in fabricating components that operate reliably under severe conditions.
