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.

Specifications of 1 to 30kg Graphite Melting Crucible With Ceramic sleeve Set
1 to 30kg Graphite Melting Crucible with Ceramic Sleeve Establish
Solid and Trusted Design
This graphite melting crucible holds from 1 to 30 kilograms of steel. It functions well for melting gold, silver, copper, light weight aluminum, and various other non-ferrous metals. The crucible is made from high-purity graphite. This material provides it fantastic heat resistance and lengthy life span. It can manage temperatures up to 3000 ° C without splitting or deforming.
Integrated Ceramic Defense
Each crucible comes with a matching ceramic sleeve. The sleeve fits snugly around the exterior. It adds extra strength and safeguards the graphite from abrupt temperature level modifications. This aids prevent breakage during heating or cooling. The ceramic layer additionally decreases direct contact with fires or warm surface areas, which keeps the crucible in far better form in time.
Smooth Putting and Easy Handling
The crucible has a well-shaped putting spout. This allows you put molten steel easily and securely. There are no harsh edges or weak points near the lip. The design makes it very easy to regulate the circulation and avoid spills. Many individuals discover it basic to raise and turn using basic tongs or a crucible holder.
Consistent Efficiency Throughout Sizes
We offer this embeded in multiple sizes– from 1kg completely approximately 30kg. Every dimension follows the same quality standards. The wall surface thickness, shape, and spout angle are very carefully matched to each capacity. This makes sure stable performance whether you melt tiny precious jewelry sets or bigger commercial loads.
Fits Usual Heating Systems
The outer dimensions match most typical induction and gas furnaces. You can drop it in without custom-made modifications. The ceramic sleeve additionally aids facility the crucible inside the chamber, giving also warmth distribution. This brings about faster melting and much less thrown away energy.
Keep in mind: Constantly preheat the crucible slowly prior to complete use. This removes moisture and protects against thermal shock. Handle with tidy devices to stay clear of contamination of your melt.

5 FAQs of 1 to 30kg Graphite Melting Crucible With Ceramic sleeve Set
Frequently Asked Questions
What is this graphite crucible set used for?
This set melts metals like gold, silver, copper, and aluminum. It works in high-temperature furnaces. The graphite crucible holds the metal. The ceramic sleeve protects it and helps keep heat inside.
How much metal can it hold?
The set comes in sizes from 1 kg to 30 kg. That means it can melt between 1 and 30 kilograms of metal at once. Choose the size that fits your work needs.
Why use graphite and ceramic together?
Graphite handles very high heat and spreads it evenly. But it can break if hit or cooled too fast. The ceramic sleeve adds strength. It also reduces direct contact with flames or furnace walls. This combo makes melting safer and more efficient.
How long does the crucible last?
Life depends on how you use it. Avoid sudden temperature changes. Do not drop it or scrape it hard. With proper care, one crucible can be used many times. Always let it cool slowly after use.
Can I use it with any furnace?
Yes, as long as your furnace reaches the needed melting temperature. Most common electric and gas furnaces work fine. Make sure the crucible fits inside your furnace chamber. Also check that the ceramic sleeve sits securely around the crucible before heating.
