This video provides a detailed showcase of the appearance, structure, and characteristics of high-purity alumina (Al₂O₃) cylindrical crucibles (also known as corundum crucibles). These cylindrical crucibles are made from over 99% pure alumina, featuring a smooth, pure white surface, high density, and compact structure. They offer excellent high-temperature resistance (long-term use up to 1650°C, short-term up to 1800°C), superior chemical corrosion resistance, and outstanding thermal shock resistance, making them unlikely to crack. Key Features:

• High purity Al₂O₃ > 99%, strong chemical inertness, ensuring no contamination of samples
• Resistant to rapid cooling and heating, ideal for use in high-temperature furnaces
• Cylindrical design for easy sample heating, melting, and stirring
• Slip casting process ensures uniform wall thickness and high mechanical strength

Widely used in laboratory analysis of metal/non-metal samples, precious metal melting, ceramic powder sintering, rare earth material calcination, thermogravimetric analysis (TGA), and more. Applicable in fields such as chemistry, metallurgy, materials science, and lithium battery cathode materials. The video displays real products of various specifications of cylindrical crucibles, including different capacities (e.g., 50ml-500ml) in cylinder shapes, with support for custom sizes.
