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.

High-Purity Graphite Crucibles for Steel Melting

Our high-purity graphite crucibles are constructed for significant steel melting job. They are available in 3 standard dimensions: 3kg, 5kg, and 10kg capacity. Each crucible is made from premium-grade graphite that provides strong performance under intense warmth.

Trick Includes

Extreme Warm Resistance: These crucibles deal with temperatures as much as 3000 ° C without splitting or deforming. That makes them suitable for melting gold, silver, copper, light weight aluminum, and other usual metals.

Pure Graphite Product: We make use of just high-purity graphite with minimal contaminations. This keeps your melted metal tidy and devoid of unwanted contamination during the procedure.

Durable Building and construction: The dense framework of the graphite gives these crucibles superb thermal shock resistance. They last much longer, even with duplicated heating and cooling cycles.

Smooth Inside Surface Area: The inside wall surface is finely completed to reduce metal sticking. This helps you pour cleanly and recuperate more of your product after each thaw.

Available Sizes

• 3kg Crucible: Finest for small-scale casting, jewelry making, or laboratory usage.
• 5kg Crucible: Great for medium workshops and regular melting tasks.
• 10kg Crucible: Designed for industrial applications or high-volume production runs.

All crucibles are ready to utilize ideal out of package. No pre-firing or special treatment is needed. Simply place in your heater, include your steel, and start melting. Their regular quality ensures dependable results each time.

High-Purity Graphite Crucibles for Metal Melting

Constructed for Performance and Dependability

These graphite crucibles are made from high-purity graphite. They handle extreme warm without breaking down. That makes them perfect for thawing steels like gold, silver, copper, light weight aluminum, and more. Each crucible is created to hold 3kg, 5kg, or 10kg of molten metal, so you can choose the dimension that fits your job.

Why pick these crucibles?
They warm up quickly and keep temperature stable. This conserves time and gas during melting. The material stands up to thermal shock, so it won’t fracture when heated or cooled promptly. Their smooth inner surface helps put metal easily and lowers waste.

Long lasting and lasting
High-density graphite implies much less wear gradually. These crucibles last much longer than standard ones, despite having daily use. They additionally withstand chemical reactions with a lot of steels, maintaining your thaw tidy and pure.

Developed for real-world use
Each crucible has a strong shape that fits common heating systems and tongs. The rim is strengthened to avoid cracking throughout handling. Whether you run a little foundry, fashion jewelry workshop, or laboratory, these crucibles offer regular outcomes each time.

Use them for spreading, refining, or alloying. They work well in induction heating systems, gas-fired configurations, and electrical melters. Just match the crucible dimension to your batch requires– 3kg for little jobs, 5kg for medium runs, and 10kg when you require higher outcome.

Clean them after each usage by cleaning off deposit. Stay clear of sudden temperature level modifications to obtain one of the most life out of them. With appropriate care, they supply trusted efficiency day after day.

5 FAQs of graphite crucible high purity 3kg melting metal 5kg 10kg graphite crucibles for

Frequently Asked Questions About High-Purity Graphite Crucibles

What is a high-purity graphite crucible used for?

These crucibles melt metals like gold, silver, copper, and aluminum. They handle high temperatures without breaking down. People use them in foundries, labs, and jewelry making.

Why choose high-purity graphite?

High-purity graphite resists chemical reactions. It keeps your metal clean during melting. Lower purity can add impurities to your melt. That affects quality and color, especially with precious metals.

What sizes do you offer?

We offer 3kg, 5kg, and 10kg capacity crucibles. The size tells you how much metal it can hold when melted. Pick the one that fits your usual batch size. A larger crucible gives room for safe pouring.

How long does a graphite crucible last?

Life depends on use and care. Avoid sudden temperature changes. Do not drop or hit the crucible. With proper handling, it can last many melts. Always preheat slowly before full use.

Can I use the same crucible for different metals?

It’s best to use one crucible for one metal type. Mixing metals can cause cross-contamination. Leftover traces from one metal may affect the next melt. This is very important for pure or precious metals.
