Specification of High Purity Cylindrical Al2o3 Ceramic Corundum Aluminum Oxide Crucible for Laboratory Melting

This ceramic crucible handles severe warmth in labs. It’s made from pure aluminum oxide, additionally called alumina or corundum. The product grade is high purity, commonly 99.5% Al2O3 or higher. This purity issues. It means less pollutants get into your thaw. High pureness alumina endures temperatures over 2000 ° C. This makes it excellent for melting steels, alloys, or preparing various other high-temperature materials.

The crucible form is round. This layout gives excellent stability on a lab bench or inside a furnace. It heats up evenly. The thick walls include stamina. They stand up to thermal shock far better than thinner crucibles. Abrupt temperature modifications occur. This crucible handles them well. It will not fracture quickly.

Chemical resistance is one more crucial quality. Alumina resists assault from many acids and bases. It also resists molten steels and slags. This resilience suggests the crucible lasts longer. You get more usages from it. It saves cash in time.

These crucibles come in various sizes. Usual sizes hold from 5ml up to 500ml or more. Select the size matching your example quantity. The smooth interior surface is essential. It protects against product sticking. Cleansing is much easier after usage. You just clear the melt. The crucible surface stays tidy.

Its high melting point and security make it ideal for demanding applications. Utilize it in electrical resistance furnaces, induction furnaces, or muffle heaters. Typical jobs include melting precious metals like silver or gold. It helps platinum team steels also. It thaws numerous alloys. It prepares specialized glasses or crystals. This crucible supplies dependable efficiency.

5 FAQs of High Purity Cylindrical Al2o3 Ceramic Corundum Aluminum Oxide Crucible for Laboratory Melting

Here are 5 common questions about our High Purity Cylindrical Al2O3 Ceramic Corundum Aluminum Oxide Crucibles for lab melting:

What’s the highest temperature this crucible can handle? It withstands temperatures up to 1750°C continuously. Short bursts up to 1800°C are possible. Exceeding this limit risks damage. Always check your specific material’s melting point first.

Can this crucible handle sudden temperature changes? Yes, it resists thermal shock very well. This crucible cools down or heats up quickly without cracking usually. Avoid plunging it directly from extreme heat into cold water. Let it cool naturally for best results.

What chemicals or materials should I avoid melting in it? Do not use strong alkalis like sodium hydroxide or hydrofluoric acid. These chemicals attack the alumina. Avoid highly reactive metals like titanium or zirconium. They can react with the crucible material. Stick to common metals, oxides, and salts.

How do I clean the crucible after use? Let the crucible cool completely first. Remove loose residue with a brush or compressed air. Soak it in warm, dilute hydrochloric acid or nitric acid if needed. Rinse it thoroughly with pure water afterward. Dry it completely before the next use. Never use abrasive cleaners.

How many times can I reuse this crucible? It depends heavily on the materials melted and the operating temperatures. Used carefully with compatible materials, it lasts for many heating cycles. Inspect it closely before each use. Look for cracks, chips, or significant wear. Replace it immediately if you see damage. Its lifespan is long with proper care.
