99% Alumina Ceramic Crucible– High-Performance Refractory Service

Product Composition and Pureness

This crucible is made from 99% pure alumina (Al ₂ O TWO). The high purity level makes certain superb resistance to chemical attack and thermal shock. It includes minimal pollutants, which assists keep sample integrity during high-temperature procedures.

Temperature level Resistance

The crucible can withstand constant use at temperatures up to 1750 ° C (3182 ° F). It stays stable even under quick home heating or cooling down cycles. This makes it ideal for demanding applications like ash testing, fusion, and high-temperature sintering.

Physical Residences

It features a thick, non-porous framework that stops contamination and absorption of products. The surface is smooth and very easy to clean. Its mechanical stamina stays high also when exposed to severe warmth over extended periods.

Chemical Stability

99% alumina ceramic stands up to corrosion from most acids, antacid, and molten steels. It does not respond with most research laboratory reagents or samples. This inert behavior makes sure exact and repeatable cause logical and commercial setups.

Typical Applications

These crucibles are commonly used in research laboratories, metallurgy, and materials study. Normal usages consist of loss-on-ignition tests, sample preparation for XRF evaluation, melting precious metals, and shooting ceramics or powders. Their integrity makes them a standard choice in quality assurance and R&D environments.

Available Sizes and Shapes

Standard choices consist of round and conelike types with abilities ranging from 10 mL to 300 mL. Customized measurements can be generated upon request to fulfill details procedure requirements. Each unit is meticulously examined for splits, warping, or surface area flaws prior to delivery.

Handling and Treatment

Constantly pre-heat the crucible gradually to stay clear of thermal shock. Usage correct tongs and put it on a heat-resistant surface after use. Avoid sudden temperature level modifications or mechanical effects, as these may trigger fracturing in spite of the material’s durability.

Applications of 99% Alumina Ceramic Crucibles

High-Temperature Material Handling

99% alumina ceramic crucibles handle extreme warm without damaging down. They work well in melting steels like gold, silver, and platinum. Labs and shops utilize them due to the fact that they remain steady even over 1700 ° C. Their strong framework stands up to thermal shock during rapid heating or cooling.

Chemical and Lab Usage

These crucibles stand up to most acids, alkalis, and corrosive chemicals. That makes them optimal for sample prep work, ash testing, and chemical evaluation. Scientist depend on them for precise outcomes because they do not respond with the materials inside. The high purity of 99% alumina means virtually no contamination occurs during experiments.

Glass and Ceramic Production

In glass production, these crucibles hold liquified glass without adding contaminations. Artists and suppliers rely on them for small-batch glasswork and specialty porcelains. Their smooth indoor surface protects against sticking and permits simple pouring. Duplicated usage does not wear them out promptly.

Metallurgy and Alloy Development

Engineers utilize 99% alumina crucibles to check brand-new metal alloys. The crucibles sustain accurate control over structure and temperature level. Since they do not take in or release components, the final alloy remains true to layout. This reliability matters in aerospace, automotive, and electronics industries.

Heat Therapy and Sintering

During sintering of powders or warm treatment of components, these crucibles give a tidy, inert atmosphere. They aid keep constant quality in innovative ceramics and digital elements. Their resilience means less substitutes and reduced lasting expenses.

These crucibles are produced tough jobs where performance and pureness can not be compromised. Users pick them repeatedly since they provide constant results under demanding conditions.

5 FAQs of 99% alumina ceramic crucible 99 refractory ceramic crucible ceramic crucible

Frequently Asked Questions About 99% Alumina Ceramic Crucibles

What is a 99% alumina ceramic crucible?

A 99% alumina ceramic crucible is made mostly from aluminum oxide (Al₂O₃). It contains at least 99% pure alumina. This high purity gives it strong heat resistance and chemical stability. People use it in labs and industries for melting, heating, or holding materials at very high temperatures.

Why choose 99% alumina over other ceramics?

99% alumina has better performance than lower-grade ceramics. It can handle temperatures up to 1750°C (3182°F) without deforming. It resists corrosion from acids, bases, and molten metals. Its low thermal expansion also means it won’t crack easily during fast heating or cooling.

Can I use this crucible with all types of samples?

Most samples work well with 99% alumina crucibles. However, avoid using them with strong alkalis like sodium hydroxide or potassium hydroxide at high heat. These can react with alumina and damage the crucible. Also, do not use with hydrofluoric acid—it will eat through the material.

How do I clean and maintain the crucible?

Let the crucible cool down fully before cleaning. Use a soft brush to remove loose residue. For stuck-on material, soak it in diluted acid (like nitric acid) or water, then gently scrub. Never use metal tools—they can scratch or chip the surface. Store it in a dry place to prevent moisture buildup.

How long does a 99% alumina crucible last?

Its life depends on how you use it. With proper handling—avoiding sudden temperature changes, mechanical shock, and reactive chemicals—it can last for many uses. Inspect it regularly for cracks or glaze changes. Replace it if you see any damage to keep your results accurate and safe.
