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 Gold Melting Graphite Crucible Induction Heating Crucible For Aluminium With Stopper K3

This graphite crucible melts gold and aluminum efficiently. Many customers ask similar questions before buying. Here are five common ones.

What material is the crucible? It uses high-purity graphite. This material handles extreme heat well. Graphite resists chemical reactions with molten metals. This keeps your aluminum pure. It also conducts heat effectively for melting.

What temperature can it handle? The K3 crucible withstands very high temperatures. It works perfectly for melting aluminum. Aluminum melts around 1220°F (660°C). This crucible easily handles that. It can manage much higher temperatures safely. Always check the exact specs for your model.

How long does the crucible last? Lifespan depends on usage. Careful handling extends its life. Avoid sudden temperature changes. Thermal shock can crack graphite. Protect it from physical bumps. Proper use gives many melting cycles. Watch for signs of wear. Replace it if cracks appear or walls thin.

What does the stopper do? The stopper controls molten metal flow. You lift it to pour. You close it to stop. This offers precise pouring control. It prevents spills. It keeps metal hot inside longer. This is essential for careful casting work. The stopper fits the crucible opening tightly.

How do I care for this crucible? Let it cool down slowly after use. Don’t quench it in water. Thermal shock damages graphite. Clean out leftover metal slag gently. Store it in a dry, safe place. Avoid dropping or hitting it. Inspect it before each use for cracks. Proper care makes it last.
