Specification of High 99 Alumina corundum ceramic crucible

This High Pureness 99% Alumina Diamond Porcelain Crucible is made for demanding high-temperature tasks. It endures extreme heat incredibly well. Its maximum service temperature level reaches 1800 ° C (3272 ° F). Short-term usage can handle also greater spikes. The crucible resists abrupt temperature adjustments efficiently. It won’t crack conveniently from quick heating or air conditioning. This thermal shock resistance is essential for many lab and commercial processes.

The product boasts outstanding chemical security. It strongly resists assault from acids, alkalis, and numerous liquified steels. This inertness ensures your examples continue to be uncontaminated. The crucible will not react with the materials you refine inside it. You get trusted outcomes every time. Its high density, around 3.9 g/cm ³, contributes to this strength and chemical resistance. The securely loaded corundum framework inconveniences.

Mechanical strength is an additional essential function. This alumina ceramic possesses high firmness and good resistance to wear. It lasts longer under severe problems compared to reduced purity options. Surface coating is typically really smooth. This minimizes material sticking and simplifies cleansing after usage. Crucibles can be found in numerous basic shapes and sizes. Common options consist of tall form, low form, and boat styles. Customized sizes are commonly offered. The crucible features a level, secure base for secure placement in furnaces or kilns. Its walls are uniformly thick for constant home heating. This crucible works accurately in air, inert gas, or vacuum cleaner settings. It’s necessary tools for melting, calcining, sintering, and high pureness sample analysis. Its performance justifies the financial investment for crucial applications. You require a crucible that executes continually under extreme heat and chemical exposure. This High 99 Alumina crucible delivers that integrity. Your products stay pure inside it.

Applications of High 99 Alumina corundum ceramic crucible

High 99 alumina diamond ceramic crucibles are important devices. They handle extreme conditions many materials can not. Their near-pure alumina composition is essential. This provides exceptional properties. These crucibles endure incredibly high temperatures quickly. Temperatures over 1700 ° C are no problem. They withstand abrupt temperature level modifications well. This thermal shock resistance issues for repeated home heating and cooling down cycles.

Chemical inertness is one more major benefit. High-purity alumina resists strike from many rough materials. Acids, bases, and molten salts typically do not harm it. This makes the crucibles secure for aggressive chemical procedures. You obtain very little contamination of your samples or thaws. Product purity remains high.

These residential or commercial properties open lots of uses. Crucibles work flawlessly for melting rare-earth elements like gold and platinum. Jewelers and refiners rely on them. They are crucial in innovative material research. Researchers utilize them to establish brand-new alloys and porcelains. Semiconductor production requires them for refining high-purity silicon and various other electronic materials. Analytical labs depend upon them for precise sample prep work and screening. Heat treatment processes for specialized steels utilize them too. They manage unusual earth aspects efficiently.

Mechanical toughness is necessary. Alumina diamond crucibles are difficult and durable. They stand up to wear and abrasion. This expands their useful life. Cautious handling is still required. Prevent sharp influences. Follow recommended heating and cooling rates. This prevents thermal stress cracks. Correct use makes sure dependable efficiency over time. You obtain value from your investment. These crucibles are a practical choice for demanding high-temperature work.

5 FAQs of High 99 Alumina corundum ceramic crucible

What exactly is High 99 Alumina ceramic?
It’s a super pure ceramic. Over 99% of it is aluminum oxide. This makes it incredibly hard. It handles extreme heat very well. This purity is key for crucible performance.

How hot can these crucibles safely get?
They handle very high temperatures. The maximum continuous use is around 1750°C. Short bursts can reach 1800°C. This suits most demanding lab and industrial melting jobs. Check the specific grade for exact numbers.

What chemicals won’t damage the crucible?
It resists many harsh substances. Acids and alkalis struggle to attack it. Molten metals like gold or platinum don’t react with it well. Strong bases might cause some etching over time. Avoid hydrofluoric acid completely.

Will the crucible last a long time?
Yes, it’s very durable. The high purity alumina resists wear and thermal shock better than cheaper ceramics. Its lifespan depends on how you use it. Extreme temperatures, rapid cooling cycles, or rough handling shorten its life. Treat it carefully for maximum use.

Is special care needed when using it?
Handle it gently. Avoid bumps or drops. Thermal shock is a risk. Heat it up slowly. Let it cool down slowly too. Sudden temperature changes can cause cracks. Use proper tools designed for ceramic crucibles. Don’t use metal tools inside it.
