Overview of Mullite Crucible

Mullite crucibles are made from a high-performance ceramic material composed primarily of alumina (Al₂O₃) and silica (SiO₂). Known for their excellent thermal stability and mechanical strength, mullite crucibles are widely used in high-temperature applications such as melting metals, glass, and ceramics. They offer superior resistance to thermal shock and chemical attack, making them indispensable in both laboratory and industrial settings.

Features of Mullite Crucible

Thermal Shock Resistance: Exceptional ability to withstand rapid temperature changes without cracking.
High Mechanical Strength: Strong and durable, even at elevated temperatures.
Chemical Stability: Resistant to most chemicals, ensuring minimal contamination during processes.
Temperature Range: Can operate effectively at temperatures up to 1650°C.
Low Thermal Expansion: Minimal expansion or contraction with temperature changes, ensuring dimensional stability.
Non-Reactive: Does not react with the materials being processed, preserving sample purity.
Versatility: Suitable for a wide range of applications including metallurgy, glass manufacturing, and laboratory experiments.

5 FAQs of 1 to 30kg Graphite Melting Crucible With Ceramic sleeve Set

What’s the maximum temperature this crucible set can handle?
The crucible works safely up to 2800°C. The ceramic sleeve adds insulation. This combo prevents heat loss. It suits metals like gold, silver, or copper. Avoid exceeding the limit to prevent cracks.

How long does the crucible last?
Lifespan depends on usage frequency and materials melted. Regular use with non-corrosive metals may last 6–12 months. Rough handling or extreme temperatures shorten this. Clean after each melt to extend durability.

Is the ceramic sleeve necessary?
Yes. The sleeve protects the crucible from direct flame. It reduces thermal stress. Without it, the crucible might crack faster. The sleeve also improves heat distribution. Always use both parts together.

Can this set work with any furnace?
It fits most standard furnaces designed for 1–30kg capacities. Check inner dimensions before buying. The crucible’s base diameter must match the furnace’s heating zone. Contact the seller for compatibility details.

How do I clean the crucible after melting?
Let it cool completely. Remove residue with a soft brush or dry cloth. Avoid water or chemicals. Moisture causes cracks. For stubborn debris, heat the crucible slightly and scrape gently. Store it dry.
