Specification of Alumina Al2O3 Ceramic Porcelain Crucible 5ml-2000ml Cylindrical/Flat Bottom/Curved for Furnace Ceramic Parts

These alumina ceramic crucibles handle high heat jobs. They come in sizes from 5ml to 2000ml. You pick the size you need. The material is pure Al2O3 ceramic. This stuff is tough. It handles temperatures way over 1500°C. That’s very hot. The crucibles resist thermal shock. They won’t crack easily going from hot to cold. They also resist chemicals. Acids and bases won’t eat them up fast. They stay strong a long time.

You get different bottom shapes. Cylindrical is common. Flat bottom gives good stability. Curved bottom helps pour liquids out clean. Each shape has its place. The smooth inside surface prevents sticking. Samples won’t grab hold. Cleaning is easier later.

People use these crucibles in labs. They melt stuff. They analyze materials. They run tests needing high heat. Factories use them too. Firing ceramics. Processing metals. Any furnace work needing a solid container. Alumina lasts. It saves money over cheaper options. You get what you pay for. These crucibles do their job well.

Applications of Alumina Al2O3 Ceramic Porcelain Crucible 5ml-2000ml Cylindrical/Flat Bottom/Curved for Furnace Ceramic Parts

Alumina ceramic crucibles are very useful. People need them in labs and factories. Alumina is a special material. It is made from aluminum oxide, Al2O3. This makes it very strong. It handles very high heat well. Crucibles made from it can go into very hot furnaces. They don’t break easily. They also resist chemicals. Acids and bases don’t damage them much. This is important for many jobs.

These crucibles come in many sizes. You can get small ones holding just 5ml. You can get large ones holding 2000ml. That’s a big range. Different jobs need different sizes. The shape matters too. You can choose cylindrical ones. These look like straight tubes. You can get flat bottom crucibles. These stand firmly on surfaces. There are also curved bottom designs. Each shape suits a specific task.

People use these crucibles for melting things. They melt metals like gold or silver inside them. The alumina doesn’t react with the hot metal. People also use them for heating other materials. They heat powders or chemicals. The crucible holds the material safely. It is good for chemical analysis. Scientists heat samples to see what they are made of. The crucible doesn’t add anything to the sample. It stays clean. It is also good for heat treatment. People change how materials behave by heating them carefully. The crucible provides a stable container.

The alumina ceramic is durable. It lasts a long time. It withstands sudden temperature changes. This is called thermal shock resistance. You can heat it up fast or cool it down fast. It usually doesn’t crack. This saves money because you buy fewer replacements. It works well in many furnace types. It works in regular lab furnaces. It works in bigger industrial furnaces too. These crucibles are essential tools for high-temperature work. They are reliable and perform well.
