99% Alumina Ceramic Crucible, High Purity Lab Crucible for Furnace, Metal Melting, Chemical Analysis & Research (2ml–1000ml) (Alumina,90Ml Outer Diameter 35, Height 120)

Product Description： This high-purity alumina (corundum) boat is designed for reliable performance in high-temperature applications up to 1600°C. Each piece is precision slip-cast and sintered at 1800°C, ensuring excellent mechanical strength, chemical resistance, and thermal stability. Ideal for laboratory furnaces, material testing, and metal or ceramic sintering. For best results and extended lifespan, use with controlled heating and cooling rates. Please note: the included lid serves as a protective dust cover only and is not airtight.

• Crafted from 99% pure alumina ceramic, this crucible delivers exceptional thermal stability and shock resistance. It offers superior corrosion resistance against acids and alkalis, ensuring minimal sample contamination for reliable high-temperature processing.
• The cylindrical shape promotes uniform heat distribution and is easy to load and unload from furnaces.
• Ideal for a wide range of high-temperature applications, including sample preparation, metal and ceramic melting, ash testing, and sintering. This crucible is versatile for use with various powders, metals, and chemicals in research, academic, and quality control labs.
• Offered in a comprehensive range of standard capacities from 20ml to 500ml to suit various experimental scales. Each unit is precision-engineered for consistent wall thickness and reliable thermal performance.
• Crafted from 99% alumina and sintered at 1800°C for 40 hours, this crucible guarantees exceptional durability and thermal stability. Designed for sustained use up to 1600°C, it maintains structural integrity over repeated heating cycles. For optimal longevity, we recommend a controlled heating rate and use with non-reactive materials in muffle or tube furnaces.
