5 FAQs of Alumina Ceramic Laboratory Crucible Al2O3 Ceramic Corundum Crucible

What is an alumina ceramic laboratory crucible? An alumina ceramic laboratory crucible is a high-temperature resistant container made from aluminum oxide (Al2O3), also known as corundum. It is designed for heating, melting, or calcining materials in laboratory and industrial settings. Its superior thermal stability, chemical resistance, and mechanical strength make it ideal for applications involving extreme temperatures and reactive substances.

What temperature can an alumina ceramic crucible withstand? Alumina ceramic crucibles can withstand temperatures up to 1700°C (3092°F) in continuous use and up to 1800°C (3272°F) for short-term operations. Their high melting point and low thermal expansion ensure minimal deformation or cracking, even under rapid temperature changes. This makes them suitable for processes like metal smelting, ash analysis, and high-temperature sintering.

Are alumina ceramic crucibles chemically resistant? Yes, alumina ceramic crucibles exhibit excellent resistance to acids, alkalis, and corrosive gases at high temperatures. They are inert to most chemicals except hydrofluoric acid and strong alkaline solutions, which can cause erosion over time. This chemical stability ensures minimal contamination of samples, making them reliable for precise laboratory experiments and industrial processes.

What applications are alumina ceramic crucibles used for? These crucibles are widely used in laboratories and industries for melting metals, glass production, ash content testing, and heat-treating powders. They are also employed in material science research, semiconductor processing, and chemical analysis. Their durability and purity make them suitable for environments requiring contamination-free results and repeated high-temperature use.

How do I clean and maintain an alumina ceramic crucible? Clean the crucible by soaking it in diluted hydrochloric acid or a cleaning solution, then gently scrubbing with a soft brush. Avoid abrasive materials that could damage the surface. Dry thoroughly before reuse. To prevent thermal shock, avoid sudden temperature changes—preheat gradually and cool slowly. Store in a dry environment to maintain integrity and longevity.
