Crucible

A crucible is a ceramic or metal container used for heating substances at high temperatures. Its primary function is to withstand extreme heat and chemical reactions without degrading or contaminating the material being heated.

Material:

Crucibles are constructed from a variety of materials chosen based on the specific application and temperature requirements. Common materials include:

• Graphite: Excellent heat resistance and chemical inertness, suitable for high-temperature applications and handling reactive materials. Can be porous and requires pre-treatment for certain uses.
• Porcelain: Commonly used for general laboratory applications, resistant to many acids and bases, but susceptible to thermal shock.
• Clay: Less expensive than porcelain, suitable for lower temperature applications.
• Fused Silica (Quartz): Exceptional thermal shock resistance and chemical inertness, ideal for high-temperature work with reactive substances.
• Alumina: High strength and chemical resistance, used for specialized applications.
• Platinum: Highly resistant to corrosion and can withstand very high temperatures; however, it is expensive.
• Stainless Steel: Used for lower-temperature applications where corrosion resistance is needed.

Purpose & Function:

• Melting: Used to melt metals, glass, or other materials.
• Calcination: Heating a substance to a high temperature to drive off volatile components.
• Chemical Reactions: Providing a contained environment for high-temperature chemical reactions.
• Analysis: Holding samples for analysis, such as in combustion analysis.
• Casting: Containing molten material for casting into molds.

Usage Scenarios:

• Metallurgy: Melting and refining metals.
• Chemistry Laboratories: Performing high-temperature reactions, dissolving samples, and preparing solutions.
• Glassmaking: Melting and shaping glass.
• Analytical Chemistry: Used in techniques like loss on ignition (LOI) to determine the volatile content of a sample.
• Foundries: Holding molten metal for casting.
• Jewelry Making: Melting and refining precious metals.

Common Types:

• Clay Crucibles: Inexpensive, used for general-purpose melting of metals like lead, tin, and copper.
• Porcelain Crucibles: Widely used in laboratories for heating solids and evaporating liquids.
• Graphite Crucibles: Used for high-temperature applications, often with reactive metals. Available with various grades of purity.
• Fused Silica Crucibles: Used for high-temperature work with reactive substances, such as in platinum assaying.
• Platinum Crucibles: Used for specialized applications requiring high corrosion resistance and high temperatures, such as platinum assaying and certain analytical procedures.
• Crucible Tongs: Specialized tongs designed to safely handle hot crucibles.
• Crucible Furnaces: Furnaces specifically designed to accommodate and heat crucibles.
