Alumina Crucible– High-Purity Porous Aluminum Oxide

Product and Purity

This crucible is made from aluminum oxide (Al ₂ O FIVE) with a purity of 99.5%. The high pureness makes sure minimal contamination during high-temperature applications. It includes very few contaminations, which assists preserve the stability of delicate materials during processing.

Porosity and Framework

The crucible includes a regulated permeable framework. This design enables much better gas exchange and lowers thermal stress and anxiety during heating and cooling cycles. The porosity also sustains uniform warm distribution, which is necessary for consistent cause lab or industrial setups.

Temperature Resistance

It withstands temperatures as much as 1700 ° C (3092 ° F). This makes it suitable for melting, sintering, calcining, and other high-heat processes. The product remains secure also under duplicated thermal biking, using lengthy service life without fracturing or flawing.

Chemical Security

Light weight aluminum oxide is extremely immune to acids, alkalis, and molten metals. It does not respond conveniently with a lot of chemicals, which shields both the crucible and the example inside. This chemical inertness is especially valuable when working with reactive or corrosive compounds.

Physical Characteristics

The crucible has high mechanical strength and excellent dimensional security. Its surface area is smooth yet robust, decreasing the risk of damaging during handling. Criterion sizes are available, and customized forms can be generated upon demand.

Usual Applications

These crucibles are extensively used in study laboratories, metallurgy, porcelains, and products science. They function well for ash screening, sample prep work, crystal development, and high-temperature responses. Their reliability makes them a trusted selection throughout many technical fields.

5 FAQs of Al2o3 99.5% porous aluminum oxide crucible aluminum oxide crucible Alumina Crucible

Frequently Asked Questions About 99.5% Al₂O₃ Porous Aluminum Oxide Crucibles

What is a 99.5% Al₂O₃ porous alumina crucible?

This crucible is made from aluminum oxide (Al₂O₃) with a purity of 99.5%. It has small open spaces inside, which makes it “porous.” This structure helps with gas flow and thermal stability during high-temperature use.

Why choose a porous alumina crucible over a dense one?

Porous crucibles allow gases to pass through more easily. This is useful in processes like sintering or ash testing where trapped gases can cause problems. The porosity also reduces thermal shock risk compared to fully dense versions.

What temperatures can this crucible handle?

It works well up to 1700°C (3092°F). At this temperature, it stays strong and keeps its shape. Always stay below the maximum rating to avoid damage or contamination.

Is it safe to use with reactive materials?

Yes, but with limits. High-purity alumina resists most acids, bases, and molten metals. However, avoid contact with strong alkalis like sodium hydroxide or hydrofluoric acid. These can attack the crucible and shorten its life.

How do I clean and reuse the crucible?

Let it cool completely first. Remove residue with a soft brush or compressed air. For tougher buildup, heat it gently in a furnace to burn off organics. Never use water on a hot crucible—it can crack from sudden cooling. Store it dry and away from dust when not in use.
