Alumina Crucible, 1750 °C, is a highly important container used to facilitate the transition of metals from a solid to liquid state. When melting precious metals, the choice of crucible is crucial. Among the several options available, alumina ceramic crucibles stand out due to their exceptional properties and benefits.

FEATURE

• High-Temperature Resistance: Alumina crucibles are designed to resist extremely high temperatures without melting or deforming.
• Chemical Inertness: Alumina doesn’t easily react with acids, bases, or other chemicals, making it resistant to chemical reactions.
• Thermal Shock Resistance: They are manufactured to avoid cracking during rapid temperature changes.
• Variations in Shapes and Sizes: It comes in different shapes, such as rectangular crucibles, circular crucibles, cylindrical crucibles, or irregularly shaped crucibles.
• Compatibility: They are compatible with different laboratory equipment, such as tube furnaces, muffle furnaces, and kilns.
• Longevity: They have a relatively long lifespan due to their resistance to thermal and chemical stresses.
• Non-magnetic: Alumina is non-magnetic, making it suitable for applications where magnetic interference is a concern.
• Scientific and Industrial Use: These Crucible Boats are essential tools in scientific research, quality control, and industrial processes involving high temperatures and reactive materials.
• Electrical Insulation: An electrical insulator can be advantageous in applications with undesirable electrical conductivity.
• Versatility: They are used in various fields, including materials science, chemistry, metallurgy, and more.
