Specification of Cylindrical corundum semicircle / porcelain 99% alumina al2o3 high temperature resistance crucible

This crucible is created high warmth job. It’s shaped like a cyndrical tube cut in half lengthwise. Think of a tube cut down the center. This semicircle form is sensible. It lets you quickly put materials inside or remove residues after heating. You get excellent accessibility without a full cylinder shape.

The material is premium. It uses 99% pure alumina (Al two O FIVE). This is additionally called diamond or high-alumina porcelain. Such high pureness is key. It offers the crucible its stamina and resistance. It takes care of severe temperatures easily. Anticipate reputable performance as much as 1800 ° C (3272 ° F). This makes it perfect for labs and industry requiring extreme warmth.

Durability is a major plus. The high alumina material implies it is difficult. It stands up to damage from continuous use. It takes care of abrupt temperature level changes well. You will not see splits from heating or cooling also quickly. Chemical resistance is an additional advantage. Acids and bases will not damage it quickly. This keeps your examples pure. There’s no contamination from the crucible itself.

Regular dimensions are simple. Usual inside sizes are around 50mm, 60mm, or 70mm. Heights are often 70mm, 80mm, or 100mm. Wall surface density is solid, generally 5-7mm. These dimensions supply good capacity and stability. You recognize it will sit safely on a heating system rack.

Use this crucible for numerous requiring tasks. It’s ideal for melting steels like gold or silver. It benefits sintering ceramic powders. It’s terrific for high-temperature chemical evaluation. Heating system work including ash testing or fluxing is not a problem. It takes care of calcination processes accurately. Its shape streamlines packing powders or small parts. Cleaning after usage is straightforward.

Applications of Cylindrical corundum semicircle / porcelain 99% alumina al2o3 high temperature resistance crucible

These round corundum semicircle crucibles are made from 99% pure alumina (Al2O3). This product is incredibly difficult. It handles extreme warm quite possibly. You need crucibles that won’t fall short under heats. These are excellent for that. They resist temperature levels far past what numerous steels thaw at. Assume platinum or other precious metals. Labs use them frequently for melting and screening.

Thermal shock resistance is another huge plus. The crucible won’t split conveniently if you heat it quick or trendy it down rapidly. This is essential for numerous industrial work. Unexpected temperature changes happen usually. You require devices that can take it. These crucibles can.

Chemical inertness is crucial as well. The 99% alumina does not react with most things. Acids, bases, molten salts, slags– they typically do not affect it. Your example stays pure. The crucible doesn’t pollute your products. This is crucial for precise evaluation or making pure products.

The semicircle form is practical. It fits well in round heaters. Heat transfers equally. Handling is easier too. You see them utilized in many places. Research study laboratories examine ores or develop new alloys. Universities teach students high-temperature chemistry. Metallurgical plants fine-tune steels. Ceramic manufacturing facilities fire unique glazes or parts. Jewelers thaw silver and gold. Glassmakers try out brand-new formulas.

Longevity matters for price. These crucibles last a lot longer than less expensive alternatives. You replace them much less often. This saves cash gradually. They stand up to repeated heating cycles well. Regular performance is assured. You get reliable results batch after batch.

High purity alumina makes sure marginal communication. Your procedures remain cleaner. Material loss is reduced. The crucible surface area remains smooth. Absolutely nothing sticks quickly. Cleaning up is less complex after usage.

5 FAQs of Cylindrical corundum semicircle / porcelain 99% alumina al2o3 high temperature resistance crucible

What material is this crucible made from?
It uses 99% alumina. Alumina is Al2O3. This is very pure ceramic. It is a type of corundum. Porcelain describes its smooth, hard finish. This material handles extreme heat well.

How hot can this crucible get?
It withstands very high temperatures. Use it safely up to 1700°C (3092°F). It handles short bursts even hotter. This crucible resists thermal shock reasonably well. Avoid sudden temperature jumps. They can cause cracks.

Why is it shaped like a semicircle?
The semicircle shape offers advantages. It fits snugly against furnace walls. This improves heat transfer inside the furnace. It saves space too. The shape also makes pouring melted materials easier. Less spills out.

Will chemicals damage this crucible?
It resists chemical attack strongly. Acids and alkalis generally don’t harm it. Strong acids like hydrofluoric acid will damage it. Strong molten alkalis can also attack it. It works well with metal melts and most fluxes. Check compatibility for your specific chemicals.

How should I handle this crucible?
Handle it carefully. Alumina ceramic is strong but brittle. Avoid impacts and drops. Support it fully during heating and cooling. Don’t place it on cold surfaces when hot. Let it cool down slowly inside the furnace. Clean it gently after use. Avoid harsh abrasives. Proper care extends its life.
