Specification of Cylindrical Alumina Ceramic Crucible , Al2o3 Crucible, Refractory Crucible

Round alumina ceramic crucibles use trusted performance for demanding high-temperature jobs. These crucibles are mainly made from light weight aluminum oxide, known as Al2O3. Common purity degrees range from 95% to 99.5%. Higher pureness usually implies far better chemical resistance and longer life span. The material features high thickness. This thickness supplies superb resistance to chemical attack from many molten metals, salts, and slags. It likewise reduces contamination of your sample product.

These crucibles are formed like cylinders. They can be found in numerous conventional dimensions. Usual capabilities include 5ml, 10ml, 25ml, 50ml, 100ml, and bigger. You can discover them with various wall thicknesses. Thicker walls offer higher strength. Thinner walls enable quicker cooling and heating. Both the within and outside surface areas are smooth. This smooth finish helps protect against product sticking. It additionally makes cleansing less complicated after usage. Crucibles frequently have a flat bottom. This level base makes certain secure positioning on heating system surfaces or lab devices.

Alumina ceramic crucibles take care of severe heat effectively. They resist thermal shock properly. This suggests they can make it through quick temperature changes without fracturing. The maximum continual usage temperature is commonly around 1650 ° C to 1750 ° C. Short-term exposure to also greater temperatures is often possible. Crucibles keep excellent mechanical strength also near their top temperature restrictions. They withstand deformation under tons at high warmth. Reduced thermal conductivity aids preserve energy during home heating procedures.

Individuals utilize these crucibles in many commercial and research study settings. Typical applications entail melting metals like gold or platinum. They appropriate for alloy preparation. Ceramic crucibles work well for sintering powders. They are utilized in analyzing mineral examples. Crucibles offer in chemical synthesis reactions calling for high temperatures. They are necessary for ash content screening in different materials. Laboratories rely on them for sample fusion and fluxing procedures. Heating systems frequently utilize alumina crucibles for holding molten products.

5 FAQs of Cylindrical Alumina Ceramic Crucible , Al2o3 Crucible, Refractory Crucible

Cylindrical Alumina Ceramic Crucible FAQs

What temperature can this crucible handle?
Our cylindrical alumina crucibles withstand extreme heat. They work reliably up to 1750°C (3182°F). This makes them perfect for high-temperature melting, calcination, and sintering tasks. They resist deformation at these levels.

Can it handle sudden temperature changes?
Yes, it handles thermal shock well. The high-purity alumina material resists cracking from rapid heating or cooling cycles. This toughness is important for many lab and industrial processes. Avoid very extreme, uncontrolled temperature swings.

What chemicals won’t damage it?
Alumina ceramic resists many corrosive substances. It handles strong acids, strong bases, and molten salts very well. Hydrofluoric acid and strong phosphoric acid will attack it. Certain molten metals can also cause damage. Check compatibility for your specific materials.

How do I clean it after use?
Cleaning is straightforward. Let the crucible cool completely. Remove residue mechanically first. Use a non-abrasive tool. Soak it in a suitable acid or base solution if needed. Rinse it thoroughly with pure water. Dry it completely before reheating. Avoid thermal shock during cleaning.

How long will it last?
Crucible lifespan depends heavily on use. Factors matter: maximum temperature, thermal cycling rate, materials processed, handling care. Used correctly within its limits, it offers excellent durability. Avoid physical impacts and thermal extremes to maximize its life. Inspect it regularly for cracks or wear.
