What is Alumina's cup?

Crucible alumin is a type of crucible made of aluminum oxide or aluminum oxide - the same material used to produce aluminum metal. Krucibles are used in chemical laboratories as containers for extremely hot chemical compounds and are made of high temperature materials. The ceramic form of alumin is commonly used due to its low cost, strength and ability to withstand temperatures up to 3272 ° F (1800 ° C). Oxide rings come in various shapes and varieties and have applications in laboratory research, academic community and industry. After several cleaning processes, a substance called calcinated alumin, which usually contains alumin oxide with certain dirt, especially sodium oxide, is obtained. Calcinated aluminum oxide is often used to produce cups. Aluminum oxide with high purity can also be produced using similar processes and is often preferred in industrial laboratories due to its greater resistance to extreme heat. The melting point of alumin is approximately 3760 ° F (about 2071 ° C).Since the clay of aluminum oxide is not made of pure aluminum oxide-any high purity container can approach 100% of the aluminum oxide content can withstand temperatures so high, but can usually be trusted above 3000 ° F (about 1649 ° C).

For various uses, there is a wide range of shapes and sizes of refractory containers. For example, a high -form alumin crucible is a common accessory in many academic laboratories. The high alumin-containing cup looks like a deep, narrow cup and is often used to melt or heat the chemical on the burner Bunsen-Labor-Lobering equipment with gas flame-or in the oven. Rectangular and cylindrical options are altac commercially selling. All crucibles are used with a lid made of the same material and are processed with pliers and gloves to avoid burning or other accidents.

refractory containers useYou are usually small in academic or research laboratories, with a diameter of smaller than the size of the human hand, reflecting a small amount of chemicals that they must hold. The aluminum oxide industrial crucible that can be used for metal melting and alloys can be much larger and must be installed in a furnace with sufficient space and external support for use. Industrial containers can also be selected on the basis of the thickness of their parties, as the stronger cups tend to be more durable and have a longer life.
