Physical Properties

The crucible has a dense, non-porous framework. This prevents liquid or gas infiltration during heating. Its hardness is around 9 on the Mohs scale, supplying strong wear resistance. Regular density is 3.6 g/cm FOUR, and thermal conductivity is low– regarding 30 W/m · K at room temperature. These attributes assist it hold heat uniformly and reduce power loss.

Dimensions and Tolerance

Requirement sizes vary from 10 mL to 300 mL ability. Customized shapes and quantities are likewise readily available. Wall surface thickness is consistent, generally in between 2 mm and 5 mm, relying on dimension. Dimensional tolerance remains within ± 0.5 mm to make sure reputable suit basic lab tools.

Chemical Resistance

It stands up to strike from most acids, alkalis, and molten steels. Exceptions include hydrofluoric acid and solid antacids options at really high temperatures. This stability makes it risk-free for taking care of responsive materials without polluting samples.

Surface area End up

The internal and external surface areas are smooth and polished. This lessens deposit build-up and makes cleansing simpler after usage. The finish also lowers the chance of example attachment throughout heating or cooling cycles.

Applications of High Temperature Resistant Alumina Ceramic Crucible

Applications of High-Temperature Resistant Alumina Ceramic Crucible

Reliable Efficiency in Extreme Warmth

The high-temperature resistant alumina ceramic crucible manages warm up to 1,700 ° C without warping or damaging. This makes it suitable for jobs that require stable conditions under extreme thermal stress. Labs and manufacturing facilities depend on it for regular outcomes.

Steel and Alloy Handling

Shops and metalworking stores use this crucible to melt and cast metals like gold, silver, copper, and light weight aluminum. Its pure alumina make-up protects against undesirable responses with molten steel. That means cleaner thaws and less contaminations in the final product.

Glass and Glaze Production

Glassmakers depend on alumina crucibles when melting specialized glasses or ceramic glazes. The material withstands rust from hostile glass sets and preserves its shape even after repeated home heating cycles. This toughness minimizes downtime and substitute costs.

Study and Research Laboratory Use

In clinical labs, precision issues. Scientists make use of these crucibles for example prep work, ash testing, and high-temperature synthesis. The inert nature of alumina makes certain samples remain uncontaminated. It likewise endures thermal shock throughout rapid heating or air conditioning.

Ceramic and Powder Sintering

Throughout sintering of advanced ceramics or powdered metals, the crucible supplies a steady, non-reactive container. It supports consistent warm distribution and prevents sticking or chemical interaction with the material being refined.

Chemical Resistance for Harsh Settings

Solid acids and alkalis do not conveniently damage this crucible. That makes it appropriate for managing corrosive materials in both commercial and lab setups. Customers benefit from lengthy life span even in aggressive chemical conditions.

Its combination of warm resistance, purity, and mechanical toughness makes the high-temperature resistant alumina ceramic crucible a go-to selection across numerous demanding areas.

5 FAQs of High Temperature Resistant Alumina Ceramic Crucible

High Temperature Resistant Alumina Ceramic Crucible – Frequently Asked Questions

What is an alumina ceramic crucible made of?

This crucible is made from high-purity aluminum oxide (Al₂O₃). The material is shaped and fired at very high temperatures. This gives it strong resistance to heat and chemicals.

How hot can it get before it fails?

It can handle continuous use up to 1700°C (3092°F). Short-term exposure may go even higher. Its structure stays stable without melting or cracking under normal lab or industrial conditions.

Why choose alumina over other ceramic materials?

Alumina has better thermal stability than many other ceramics. It also resists corrosion from acids, bases, and molten metals. Plus, it does not react easily with most samples, so your results stay accurate.

Can I use it in a reducing atmosphere?

Use it mainly in oxidizing or neutral atmospheres. In strong reducing environments—especially above 1500°C—alumina may slowly degrade. Always check your process conditions before use.

How do I clean and reuse the crucible?

Let it cool fully after use. Remove residue with a soft brush or scraper. For stubborn deposits, soak it in dilute acid or water, then rinse well. Avoid sudden temperature changes. Do not use metal tools that can scratch or chip the surface. With proper care, it can be reused many times.
