Almath Crucibles Introduces Highpurity Alumina Crucibles for Hightemp Use

Imagine conducting critical experiments at extreme temperatures reaching 1750°C, where ordinary laboratory vessels would melt and deform. Researchers and industrial engineers have long struggled to find materials that can withstand such harsh conditions while maintaining experimental accuracy. Almath Crucibles Ltd. has addressed this challenge with its new CL30 Classic Alumina Crucible, offering a breakthrough solution for high-temperature applications.

The newly launched 45ml conical CL30 crucible is manufactured from high-purity recrystallized alumina (99.8%), specifically engineered for demanding high-temperature processes. This innovation represents Almath Crucibles' continued leadership in advanced ceramic materials, providing reliable solutions for scientific research and industrial applications.

• Exceptional Thermal Resistance: With a maximum working temperature of 1750°C, the CL30 crucible is suitable for metal melting, ceramic sintering, and material heat treatment processes.
• Superior Thermal Shock Resistance: The recrystallized alumina construction features large crystal grains (up to 200mm), significantly enhancing the crucible's ability to withstand rapid temperature fluctuations without cracking.
• Chemical Corrosion Resistance: The high-purity alumina ceramic demonstrates excellent resistance to acids, alkalis, and molten metals, ensuring durability and reducing replacement frequency.
• Ultra-High Purity: The 99.8% alumina composition minimizes experimental contamination while providing superior electrical and dielectric properties.
• Precision Engineering: With approximate dimensions of 41mm outer diameter, 36.5mm inner diameter, and 48mm height, the crucible ensures compatibility with standard laboratory equipment.
• British Manufacturing Excellence: Produced in the UK under strict international quality standards, the CL30 undergoes rigorous quality control throughout production.

Alumina (Al₂O₃) has become the material of choice for high-performance crucibles due to its unique properties:

• Exceptionally high melting point (2072°C)
• Superior hardness and wear resistance
• Excellent electrical insulation properties
• Outstanding chemical stability
• Biocompatibility for medical applications

Almath Crucibles employs specialized production methods to ensure product quality:
