5 FAQs of Customized Al2O3 Alumina Refractory Porcelain Corundum Ceramic Crucible

What is the maximum temperature the Al2O3 ceramic crucible can withstand?
The Al2O3 alumina ceramic crucible can withstand temperatures up to 1800°C (3272°F) in continuous use and up to 1850°C (3362°F) for short-term applications. Its high-purity alumina composition (typically 99% or higher) ensures excellent thermal stability, making it ideal for melting metals, glass, and other high-temperature processes without deforming or degrading.

Can the crucible be customized in size and shape?
Yes, these crucibles are fully customizable in dimensions, shape, wall thickness, and capacity. Common customizations include tapered designs, reinforced rims, or specialized lids. Manufacturers can also add features like pouring spouts, handles, or grooves for tongs. Custom alumina content (e.g., 95%, 99%) is available to balance cost and performance based on application requirements.

How resistant is the crucible to chemical corrosion?
Al2O3 ceramic crucibles exhibit exceptional resistance to acids, alkalis, and molten metals. They are inert to most chemicals except hydrofluoric acid (HF) and concentrated caustic solutions at high temperatures. The non-reactive surface prevents contamination of melts, making them suitable for laboratory experiments, semiconductor processing, and precision metallurgy.

Does it tolerate rapid temperature changes?
While alumina ceramic has good thermal shock resistance, extreme or abrupt temperature shifts (e.g., transferring from a 1500°C furnace to room temperature) can cause micro-cracks. To minimize risk, gradual heating/cooling (≤200°C per hour) is recommended. Crucibles with added grain structure optimization or composite materials improve thermal shock performance for demanding applications.

How should I clean and maintain the crucible?
After use, allow the crucible to cool slowly. Remove residues mechanically (soft brush) or with diluted hydrochloric acid (avoid HF). Avoid abrasive tools that scratch the surface. Store in a dry environment to prevent moisture absorption. With proper care, these crucibles last through hundreds of cycles, maintaining structural integrity and thermal efficiency. Inspect regularly for cracks or wear.
