Overview of Corundum Crucible

Corundum crucibles, made from alumina (Al₂O₃), are highly valued for their exceptional thermal resistance and chemical stability. These crucibles are ideal for high-temperature applications, such as melting and annealing processes in laboratories and industrial settings. Corundum crucibles can withstand temperatures up to 1800°C and are resistant to most chemical reagents, making them indispensable in various scientific and manufacturing operations.

Features of Corundum Crucible

High-Temperature Alumina Ceramic Tray Crucible – 45g Fire Clay Refractory Container

Premium Material for Extreme Heat

This crucible is made from high-purity alumina ceramic mixed with fire clay. The blend gives it strong resistance to heat and thermal shock. It can handle temperatures up to 1600°C (2912°F) without cracking or deforming. That makes it ideal for melting metals, ash testing, and high-temperature lab work.

Sturdy and Reliable Design

The crucible holds 45 grams of material. Its walls are thick enough to support repeated heating and cooling cycles. The shape is simple—a shallow tray with straight sides—so you can easily load and remove samples. The surface is smooth inside and out, which helps prevent material sticking and makes cleaning easier.

Built for Lab and Industrial Use

Strong and chemically inert, this crucible won’t react with most acids, bases, or molten substances. It stays stable even during long exposure to harsh conditions. Labs use it for gravimetric analysis, loss-on-ignition tests, and sample preparation. Foundries and metalworkers rely on it for small-scale melting and holding of non-ferrous metals like aluminum, copper, and zinc.

Consistent Quality You Can Trust

Every unit is fired at high temperature to ensure full densification. This removes pores and boosts mechanical strength. The result is a uniform, durable container that performs the same way batch after batch. Each crucible is inspected for cracks, warping, and size accuracy before shipping.

Use this crucible when you need dependable performance under intense heat. It’s a practical choice for anyone working in materials science, metallurgy, ceramics, or quality control labs. Keep your processes clean, safe, and repeatable with a container built to last.

High-Temperature Alumina Ceramic Tray Crucible – Built for Demanding Conditions

Exceptional Heat Resistance and Durability

This 45g fire clay refractory ceramic crucible is made from high-purity alumina. It handles extreme heat without cracking or warping. The material stays stable even at temperatures above 1600°C (2912°F). That makes it ideal for labs, foundries, and industrial settings where consistent performance matters.

Perfect for Melting, Fusing, and Ashing

Use this crucible to melt metals like gold, silver, or aluminum. It also works well for fusing glass, firing ceramics, or ashing organic samples. Its dense structure prevents contamination. Your materials stay pure because the crucible does not react with most chemicals or molten substances.

Reliable Shape and Consistent Performance

The tray-style design gives you more surface area than standard cup-shaped crucibles. This helps with even heating and faster processing. Each unit is carefully formed and fired to ensure uniform thickness and strength. You get the same reliable results every time you use it.

Suitable for Repeated Use

This crucible resists thermal shock. You can heat it quickly and cool it down without damage. It lasts through many cycles of use. Just avoid sudden temperature changes beyond recommended limits. With proper handling, it remains intact and functional for a long time.

Trusted Across Industries

Researchers, jewelers, metallurgists, and ceramic artists all depend on this type of crucible. It meets strict quality standards for lab-grade and industrial applications. Whether you are running small-scale experiments or regular production batches, this container delivers dependable service under pressure. Its simple, no-frills design focuses on function—nothing gets in the way of your work.

5 FAQs of High Temperature alumina ceramic tray crucible 45g fire clay refractory ceramic crucible container

Frequently Asked Questions

What is this crucible made of?

This crucible is made from high-purity alumina ceramic and fire clay. These materials can handle very high temperatures without breaking down. They are strong, stable, and resist chemical reactions during heating.

How much material can it hold?

The crucible holds up to 45 grams of material. This capacity works well for small-scale melting, ash testing, or laboratory sample preparation. Always leave a little space at the top to avoid spills when heating.

What temperature can it withstand?

It can safely handle temperatures up to 1600°C (2912°F). This makes it suitable for use in furnaces, kilns, and other high-heat environments. Avoid sudden temperature changes, as they may cause cracks.

Is it safe for repeated use?

Yes. The crucible is built for repeated heating and cooling cycles. Clean it gently after each use. Let it cool fully before handling or storing. Do not drop it or expose it to sharp impacts.

How should I care for this crucible?

Handle it with clean tongs to avoid contamination. Never place a hot crucible on a cold surface—it may crack. Store it in a dry place away from moisture. If residue sticks inside, heat it again gently to burn off leftover material instead of scrubbing hard.
