What is a ceramic cup?

In general, the crucible is a container or food used to hold a sample in a high temperature furnace. The ceramic cup is made of ceramic material, such as clay on the furnace. Ceramic cups are chemically and physically stable at high temperatures and are therefore used to work with materials that must be handled at very high temperatures such as metals and glasses. They are also common tools in the research environment in fields such as material science, science of country and engineering. Krucible can also be found in use in art, either for working with metals or pigments. This allows melting and handling the material inside the crucible without destroying the container. Being physically and chemicals at high temperatures is also referred to as refractory. Ceramics is commonly known in the context of ceramics and is characterized by their smooth, relatively inert surface. The inert surface or the non -peractive surface is not only useful but is essential for the cup. If the sheet ish reactive, the materials inside the crucible can start to mix with the cup content at high temperatures.

Ceramic crucible can be made of various starting materials, including silica, zircon, spinel, aluminum oxide and magnifying. The required chemical composition of the ceramic crucible depends on the application because each composition reacts differently to temperature and pressure. In particular, they are mainly oxid crucible because they are relatively cheap and can withstand a wide range of temperature environments.

Regardless of the application, a number of characteristics should be considered when choosing a ceramic cup. The chemical composition is usually the most important characteristic, as it most directly affects temperatures and pressures at which the crucible will be useful. Other relevant characteristics include total capacity, overall shape and wall thickness and bottom.

ceramic cups are used to work with metals from approximately 5000Ex. It is used in the melting of copper, tin and iron in history, the design of the cups has changed and evolved as metallurgical techniques developed. The fact that the design and use of cups has changed over time makes them historically interesting and quite useful for archaeologists. Early crucibles had irregular shape, often inconsistent in thickness and were usually not extremely refractory. The more modern circular is produced on an almost unlimited set of specifications and are used at higher temperatures and pressures than it would once be possible.
