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 Al2O3 crucible Alumina cylindrical ceramic crucible 6060mm ( diameterheight) with optional lid

Alumina Ceramic Crucible – 60 mm Diameter × 60 mm Height

Premium High-Purity Construction

This cylindrical crucible is made from 99.5% pure aluminum oxide (Al₂O₃). The material offers excellent resistance to high temperatures, thermal shock, and chemical corrosion. It maintains structural integrity even under extreme heat conditions, making it ideal for demanding laboratory and industrial applications.

Standard Dimensions with Optional Lid

The crucible measures 60 mm in diameter and 60 mm in height, providing a balanced capacity for melting, calcining, or heating small to medium sample volumes. An optional matching lid is available to help contain materials, reduce contamination, and improve temperature uniformity during use. The lid fits securely but allows for easy removal when needed.

Reliable Performance Across Applications

Thanks to its high melting point (over 1700°C) and low thermal expansion, this alumina crucible performs well in furnaces, kilns, and other high-temperature environments. It works reliably with metals, oxides, salts, and many reactive substances. The smooth interior surface minimizes residue buildup and supports easy cleaning after use.

Durable and Reusable Design

Crafted through precision sintering, the crucible features dense, non-porous walls that resist cracking and wear. This design ensures long service life and consistent results over repeated heating cycles. Users can reuse the crucible many times without significant degradation in performance.

Quality You Can Trust

Each unit undergoes strict quality checks to meet industry standards for purity, dimensional accuracy, and mechanical strength. The clean white finish reflects the high-grade alumina used in production. Whether you work in research, metallurgy, or materials science, this crucible delivers dependable support for your high-temperature processes.

High-Purity Performance for Demanding Applications

This cylindrical crucible is made from high-purity aluminum oxide (Al₂O₃), also known as alumina. It measures 60 mm in diameter and 60 mm in height, offering a reliable container for high-temperature processes. The optional lid helps control the internal atmosphere and reduces contamination during use.

Built to Withstand Extreme Conditions
Alumina crucibles handle temperatures up to 1700°C (3092°F). They resist thermal shock, chemical corrosion, and mechanical wear. This makes them ideal for melting metals, firing ceramics, ash testing, and laboratory sample preparation. Their stability ensures consistent results even under repeated heating and cooling cycles.

Clean and Inert Surface
The smooth, non-reactive interior prevents unwanted reactions with sensitive materials. This purity is essential when working with rare earth elements, oxides, or analytical samples where trace contamination must be avoided. The crucible does not release impurities, so your results stay accurate.

Versatile and Easy to Use
Designed for compatibility with standard lab equipment like muffle furnaces and tube furnaces. The uniform shape allows stable placement and easy handling. Choose the version with or without a lid based on your process needs—both options maintain the same high quality.

Trusted in Professional Settings
Researchers, metallurgists, and quality control labs rely on these crucibles daily. They meet industry standards for purity, dimensional accuracy, and performance. Each unit is carefully manufactured to ensure reliability batch after batch.

5 FAQs of Al2O3 crucible Alumina cylindrical ceramic crucible 6060mm ( diameterheight) with optional lid

Frequently Asked Questions: Alumina Ceramic Crucible (60×60 mm)

What is this crucible made of?

This crucible is made from high-purity aluminum oxide (Al₂O₃), also called alumina. It contains at least 99.5% alumina. This material gives the crucible strong heat resistance and chemical stability.

What temperature can it handle?

It can safely work at temperatures up to 1700°C (3092°F). It keeps its shape and strength even under long-term high-heat conditions. This makes it ideal for melting, sintering, or ashing in labs and industrial settings.

Does it come with a lid?

Yes, a matching lid is available as an option. The lid helps reduce contamination and loss of sample during heating. You can choose to buy the crucible with or without the lid based on your needs.

Is it safe for reactive materials?

Yes. Alumina is highly inert. It resists attack from most acids, alkalis, and molten metals. However, avoid using it with hydrofluoric acid or strong alkali fluxes like sodium peroxide at high temperatures, as these can damage the ceramic.

How should I handle and clean it?

Always handle the crucible with clean tongs. Sudden temperature changes can cause cracks, so heat and cool it slowly. For cleaning, rinse with distilled water and dry thoroughly. If needed, use mild acid washes followed by thorough rinsing. Never use abrasive tools that can scratch or weaken the surface.
