High Heat Resistant Alumina Products 99% Alumina Crucible Ceramic For Laboratory

Alumina ceramic crucible is a kind of high-temperature resistant container made of high-purity alumina, which is widely used in laboratory and industrial fields. They are famous for their excellent heat resistance, and can usually withstand high temperatures as high as 2072℃. This crucible has high thermal conductivity and can transfer heat quickly and evenly, which is very suitable for rapid heating and melting of materials.

The chemical stability of alumina ceramic crucibles makes them resistant to most acids and alkalis, which makes them particularly useful in chemical analysis and metal melting. In addition, their thermal expansion coefficient is low, which helps to reduce deformation during heating, thus improving the accuracy and repeatability of the experiment.

These crucibles also have good wear resistance and corrosion resistance, and their service life is prolonged. Alumina ceramic crucible has a variety of purity grades to choose from, ranging from 90% to 99% to meet the needs of different applications. They are usually designed as smooth surfaces, which are easy to clean and help to keep the experimental environment clean and hygienic.

However, it should be noted that the alumina ceramic crucible is not suitable for the environment containing fluoride, because fluoride may corrode the crucible. In addition, avoiding the sharp change of temperature is also the key to prolong the service life of crucible. Generally speaking, alumina ceramic crucible is an indispensable tool in high temperature experiment and industrial application.
