XTL sintyron 99% al2o3 aluminum oxide alumina ceramic crucible tray

Alumina tray crucibles are commonly used in laboratory settings for a variety of applications, such as

heating, melting, and analyzing materials. These crucibles are typically made of high-purity alumina,

a ceramic material known for its excellent thermal and chemical resistance.

The production process of alumina tray crucibles involves several steps. Firstly, high-purity alumina

powder is mixed with a binder material to form a slurry. This slurry is then poured into a mold to shape

the crucible. The mold is typically made of plaster or silicone, which helps to maintain the desired shape

of the crucible during the firing process.

Once the slurry has been poured into the mold, it is left to dry and harden. The crucible is then carefully

removed from the mold and placed in a kiln for firing. During the firing process, the crucible is heated to

high temperatures, causing the alumina powder to sinter and bond together, forming a strong and durable

ceramic material.

After firing, the alumina tray crucible is carefully inspected for any defects or imperfections. It is then ready

to be used in various laboratory applications, such as heating samples, melting metals, or performing chemical reactions.
