Specification of 99% al2o3 High temperature small alumina ceramic crucible

This alumina ceramic crucible is made from 99% pure light weight aluminum oxide (Al2O3). It uses exceptional resistance to high temperatures. The maximum functioning temperature level is 1750 ° C (3182 ° F). It takes care of fast temperature level drops well, withstanding thermal shock. This crucible is very hard and sturdy. It won’t wear down quickly throughout usage. Its surface area is extremely smooth. This level of smoothness avoids examples from sticking. Cleaning is simple later. The product is really thick, around 3.8 g/cm THREE. This thickness stops gases and fluids from leaking with. It keeps your samples had safely. Chemical resistance is one more key strength. The crucible holds up against solid acids and alkalis. It won’t rust or pollute your products. It carries out reliably in oxidizing or reducing ambiences too.

This crucible is little, created for laboratory tasks. Usual dimensions range from 5ml to 30ml capacity. You locate it made use of in precise melting job. People melt percentages of steel or glass in it. It’s perfect for ashing natural samples for analysis. It functions well for sintering small powders. Warmth therapy of little parts is another usual task. Crucible form is easy, generally a cyndrical tube with a flat base. This shape allows steady positioning in heating systems. The crucible walls are thin but solid. Thin walls permit effective warmth transfer. You heat your sample promptly and equally. Its high purity means minimal micronutrient leach out. Your outcomes stay accurate and unpolluted. You get consistent performance batch after batch. Constantly pre-heat the crucible gradually before its very first high-temperature usage. This action prevents cracking. Manage it thoroughly with tongs when warm. Avoid unexpected effects when cool to avoid damaging. Store it in a clean, completely dry location. This crucible is a reliable device for demanding high-heat applications.

Applications of 99% al2o3 High temperature small alumina ceramic crucible

This little alumina ceramic crucible contains 99% Al2O3. It manages severe warmth well. This makes it best for requiring lab and commercial tasks. It holds up against temperature levels over 1700 ° C quickly. Various other products often fall short at these levels. Its high purity alumina building and construction ensures it remains strong. It doesn’t break quickly under sudden temperature level changes. This thermal shock resistance is crucial for repeated cooling and heating.

You’ll discover it vital in steel testing. Individuals utilize it for thawing small examples of alloys. It benefits rare-earth elements like gold and silver as well. The crucible withstands chemical attack. Molten metals do not adhere to it. This keeps your example pure. You obtain precise evaluation results.

Drug stores depend on it for catalyst studies. It holds stimulant powders throughout high heat calcination. The crucible doesn’t react with the driver. You see real stimulant actions. It’s likewise important for ash content testing. Location natural examples inside. Warm them strongly up until only ash remains. The crucible survives this extreme process. You get reputable ash weight measurements.

Product researchers use it for sintering tiny ceramic components. It holds powders firmly at really heats. The crucible itself does not contaminate the sample. Tiny set chemical reactions require stable containers. This crucible gives that security. It benefits flux blends and other intense procedures. Its small size is ideal for bench-top experiments. You conserve products and energy.

Compared to lower pureness crucibles, this lasts longer. It takes care of a lot more warm cycles. It provides better resistance to chemical wear. You prevent constant substitutes. This saves cash gradually. Its smooth surface area cleans simple. You can utilize it continuously. It’s a sensible tool for major high-temperature job.

5 FAQs of 99% al2o3 High temperature small alumina ceramic crucible

Here are 5 FAQs about our 99% Al₂O₃ High Temperature Small Alumina Ceramic Crucible:

What’s the highest temperature this crucible can handle?
This crucible withstands continuous use up to 1750°C (3182°F). It handles brief exposure to even higher temperatures. Check the specific product specs for exact limits. Never exceed the maximum rated temperature.

Will chemicals damage this crucible?
The 99% alumina ceramic resists most acids and alkalis well. It handles strong bases like sodium hydroxide. It handles strong acids like sulfuric acid. Avoid hydrofluoric acid and strong phosphoric acids. These chemicals attack alumina. Check chemical compatibility before use.

Can it handle sudden temperature changes?
Handle thermal shock carefully. Heat or cool it gradually. Avoid drastic temperature jumps. Putting a hot crucible directly on a cold surface risks cracking. Pre-heating helps prevent thermal shock damage.

Is this crucible fragile?
Alumina ceramic is hard and strong. It’s also brittle. Handle it carefully. Protect it from impacts and drops. Do not clamp it too tightly. Use proper tools. Avoid mechanical stress.

How do I clean this crucible?
Remove residues after each use. Use dilute acids or bases suitable for the material. Rinse thoroughly with distilled water. Dry it completely before reheating. Avoid abrasive cleaners. They can scratch the surface.
