Specification of Refractory 5ml 25ml 50ml 100ml 300ml al2o3 alumina ceramic melting crucible with cap lid

These crucibles are for melting materials at high temperatures. They are made from alumina ceramic, specifically Al2O3. The purity is 99.7%. This high purity makes them very strong. They resist chemical attack well. You can use them with metals, salts, and glasses. They handle temperatures up to 1750 degrees Celsius. That’s very hot. This makes them good for many lab and industrial jobs.

You get them in several sizes. Choose 5ml, 25ml, 50ml, 100ml, or 300ml. Each size comes with its own cap lid. The lid helps control the melt. It also keeps things clean. The dense structure stops leaks. It also prevents the material from sticking inside.

These crucibles handle sudden temperature changes well. That’s thermal shock resistance. It means you can heat them up fast. You can cool them down fast too. They won’t crack easily. This saves time and money.

They are ideal for melting small amounts. Use them in research labs. Use them in jewelry making for precious metals. They work for small-scale alloy production too. Schools and universities use them for experiments. They are simple to use. Just put your material inside. Heat it with a torch or furnace. The alumina won’t contaminate your melt.

The surface is smooth inside and out. This makes cleaning simple after use. They are generally white or off-white in color. They arrive packed safely. Expect them in sturdy boxes. Each crucible sits in protective foam or padding. This prevents damage during shipping. The lid fits snugly on its matching crucible.

Applications of Refractory 5ml 25ml 50ml 100ml 300ml al2o3 alumina ceramic melting crucible with cap lid

These alumina ceramic melting crucibles come in handy sizes. They range from small 5ml to large 300ml. Each crucible has a matching cap lid. These lids are important. They help contain melts and reduce contamination. Alumina ceramic is a special material. It is very strong and handles high heat well. This makes it perfect for melting things.

People use these crucibles in many places. Laboratories find them very useful. Scientists melt samples for analysis. Jewelry makers use them too. They melt precious metals like gold or silver. The crucibles work well for platinum group metals. These are metals like platinum or palladium. They also work for other high-temperature metals. People use them for melting small amounts of glass. Glass artists or researchers might do this. The crucibles handle the intense heat needed.

The alumina material has great qualities. It resists very high temperatures easily. It won’t melt itself at typical furnace heats. The material is also chemically stable. Harsh chemicals or molten materials usually don’t damage it. This stability is crucial. It keeps the melted substance pure. Contamination ruins experiments or precious metals. The smooth surface helps too. It prevents samples from sticking inside. Cleaning becomes much easier later.

The cap lids are a key part. They fit snugly on the crucibles. This seal protects the melt inside. It stops dust or other stuff from getting in. It also reduces loss from spattering or fumes. Using the lid improves results. The crucibles come in different sizes for flexibility. A 5ml size is good for tiny precious samples. A 25ml or 50ml size suits many lab tests. The 100ml and 300ml sizes handle bigger batches. Jewelers melting more metal might pick these. Researchers needing larger samples choose them too.

These alumina crucibles are dependable tools. They offer a clean, stable melting environment. Their high-temperature resistance is reliable. Chemical inertness protects your materials. The cap lids provide extra safety. Choosing the right size depends on your needs. They serve well in precise melting work.

5 FAQs of Refractory 5ml 25ml 50ml 100ml 300ml al2o3 alumina ceramic melting crucible with cap lid

What sizes do your alumina ceramic crucibles come in?
We make crucibles in five useful sizes. You can choose 5ml, 25ml, 50ml, 100ml, or 300ml. Pick the size that fits your material amount best. Each one has a matching lid.

How hot can these crucibles get?
This crucible handles temperatures up to 1800°C. It works well for melting metals, alloys, or other high-heat jobs. Check your specific material’s melting point first. Make sure it’s below 1800°C.

Do I need the lid?
Yes, use the lid. It keeps heat inside the crucible better. This helps your material melt evenly. The lid also stops spills and protects against splashes. Always put the lid on during heating.

How do I handle the crucible safely?
Be careful with thermal shock. Avoid sudden temperature changes. Never put a hot crucible straight into cold water. Let it cool down slowly inside the furnace. Use proper tongs for moving it.

Can I reuse this crucible?
Yes, you can use it multiple times. Alumina ceramic is very tough. It resists wear from chemicals and high heat well. Clean it carefully after each use. Check for cracks or damage before reusing. Replace it if you see any damage.
