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

Specifications of Factory Supply High Temperature Resistant Machining 99% Al2O3 Alumina Ceramic Crucible

Factory Supply High-Temperature Immune 99% Al Two O ₃ Alumina Ceramic Crucible

Material and Pureness

This crucible is made from 99% pure alumina (Al two O TWO). The high pureness provides it outstanding resistance to chemical rust and thermal shock. It stays secure even when exposed to hostile compounds or severe heat.

Temperature level Resistance

The crucible can manage constant usage at temperature levels up to 1700 ° C (3092 ° F). It preserves its shape and stamina without splitting or flawing. This makes it optimal for melting, sintering, and high-temperature evaluation in labs and industrial setups.

Physical Qualities

It has a dense, non-porous structure that avoids contamination of examples. The surface area is smooth and very easy to clean. Its solidity is around 15– 17 Grade point average on the Vickers scale, which means it resists wear and scratching during routine handling.

Typical Applications

Individuals use this crucible in research laboratories for ash screening, sample fusion, and high-temperature reactions. Industries additionally depend on it for steel spreading, glass handling, and ceramic firing. It works well with platinum, gold, and other noble metals due to the fact that it does not respond with them.

Readily Available Dimensions and Custom Options

Requirement sizes vary from 10 mL to 500 mL capacity. Shapes include round, conical, and flat-bottom layouts. If you need an unique dimension or shape, custom-made orders are approved. Just give your exact measurements and use conditions.

Quality Assurance

Every crucible experiences rigorous high quality checks prior to delivery. We evaluate for purity, density, and thermal security. Each batch fulfills international requirements for lab and industrial ceramics. Factory-direct supply guarantees constant top quality and competitive rates.

Applications of Factory Supply High Temperature Resistant Machining 99% Al2O3 Alumina Ceramic Crucible

High-Temperature Applications of 99% Alumina Ceramic Crucibles

Dependable Efficiency in Extreme Heat

Our factory-supplied 99% Al two O ₃ alumina ceramic crucibles are constructed for demanding high-temperature settings. They manage warm up to 1750 ° C without bending, splitting, or shedding structural stamina. This makes them perfect for procedures that require constant performance under intense thermal stress.

Metal Melting and Casting

These crucibles are widely utilized in factories and steel labs. They securely have molten metals like gold, silver, copper, and light weight aluminum. The high purity of the alumina product stops undesirable reactions with the melt, making certain clean, uncontaminated results each time.

Glass and Luster Handling

Glass suppliers count on these crucibles for melting and homogenizing glass sets. Their smooth interior surface area decreases residue build-up, while their thermal shock resistance allows duplicated heating and cooling down cycles without failing. Potters and ceramic musicians also utilize them for small-batch polish preparation.

Lab and Research Usage

In research laboratories, precision matters. These crucibles supply superb chemical inertness, so they do not interfere with delicate analytical treatments. Scientists utilize them for ash screening, sample combination, and high-temperature synthesis where contamination should be prevented.

Industrial Warmth Therapy

Warmth therapy facilities utilize these crucibles to hold products throughout sintering, annealing, or calcination. Their dimensional security ensures components preserve form and integrity throughout the procedure. The crucibles also resist corrosion from many hostile ambiences and slags.

Built for Longevity
Made from thick, fine-grained 99% alumina, each crucible provides consistent wall surface thickness and very little porosity. This layout reduces the threat of leakages and extends service life– even under daily commercial usage. Our factory guarantees rigorous quality assurance so every system satisfies exacting requirements for integrity and safety.

5 FAQs of Factory Supply High Temperature Resistant Machining 99% Al2O3 Alumina Ceramic Crucible

Frequently Asked Questions

What is this crucible made of?

This crucible is made from 99% pure alumina (Al₂O₃) ceramic. It contains almost no impurities. That makes it very strong and stable at high temperatures.

How hot can it get before it fails?

It can handle continuous use at temperatures up to 1700°C (3092°F). Short-term exposure can go even higher. The material stays solid and does not melt or deform under normal high-heat conditions.

Why choose alumina over other ceramics?

Alumina has excellent thermal stability and chemical resistance. It does not react with most acids, bases, or molten metals. This makes it safe for lab work and industrial melting processes where purity matters.

Is this product suitable for repeated heating and cooling?

Yes. The crucible resists thermal shock well. You can heat it and cool it many times without cracking—so long as you avoid sudden temperature changes. Always let it heat up and cool down slowly.

Do you offer custom sizes or shapes?

We provide standard sizes for quick delivery. Custom shapes and dimensions are also available. Just share your drawing or specifications. Our factory will produce exactly what you need for your application.
