5 FAQs of Square rectangular shape laboratory refractory Ceramic Crucible

What is a square rectangular refractory ceramic crucible made of? Square rectangular refractory ceramic crucibles are typically crafted from high-purity materials like alumina (aluminum oxide) or zirconia (zirconium dioxide). These ceramics are chosen for their exceptional thermal stability, chemical inertness, and resistance to extreme temperatures. The dense, non-porous structure ensures minimal contamination during high-heat processes such as melting, calcination, or chemical analysis.

What temperature can these crucibles withstand? Most square rectangular ceramic crucibles can endure continuous temperatures between 1700°C and 1800°C (3092°F–3272°F), depending on the material. Alumina-based crucibles generally handle up to 1700°C, while zirconia variants may withstand higher ranges. Always check the manufacturer’s specifications to avoid thermal cracking or degradation during use.

Are these crucibles resistant to thermal shock? While refractory ceramics have good thermal stability, rapid temperature changes can cause stress fractures. Square rectangular crucibles are less shock-resistant than rounded designs due to their angular edges, which concentrate stress. Preheating gradually and avoiding sudden cooling (e.g., plunging into water) minimizes risks. Some advanced versions include thermal shock-resistant additives like silicon carbide for improved durability.

What applications are these crucibles suited for? These crucibles are ideal for laboratory and industrial processes requiring high-temperature containment, such as metal or glass melting, ash testing, and chemical synthesis. Their flat sides and corners make them suitable for furnace setups requiring efficient space utilization. They’re also used in material research, quality control, and educational experiments involving corrosive substances or reactive melts.

How do I clean and maintain a ceramic crucible? After cooling, remove residue mechanically (e.g., with a brush) or chemically using diluted acids like HCl or HNO3, depending on the contaminant. Avoid abrasive tools that could scratch the surface. Inspect for cracks or erosion before reuse. Store in a dry environment to prevent moisture absorption, which could weaken the structure during reheating. Proper handling ensures prolonged lifespan and consistent performance.
