XTL sintyron refractory high purity al2o3 alumina ceramic crucible

These crucibles are made from a special type of alumina ceramic material that can withstand extremely high temperatures, typically up to 1800°C or even higher, depending on the specific composition and manufacturing process. This high level of heat resistance allows the crucible to maintain its structural integrity and resist cracking or breaking when exposed to intense heat.

XTL sintyron refractory high purity al2o3 alumina ceramic crucible

The refractory alumina crucible is used for melting and holding materials at high temperatures. To use it, first heat the crucible slowly and evenly to prevent cracking. Once it reaches the desired temperature, carefully place the material to be melted into the crucible using tongs or a spatula. Allow the material to melt and then cool before removing it from the crucible.

It is important to handle the crucible with care, as it can become very hot during use. Always wear proper protective gear such as gloves and goggles when handling the crucible. Avoid sudden temperature changes, as this can cause the crucible to crack. Clean the crucible thoroughly after each use to remove any residue that may affect future melts. Store the crucible in a cool, dry place when not in use to prevent damage.
