Alumina ceramic crucible With Lids

Alumina ceramic crucible With Lids

Alumina ceramic crucibles are high-temperature resistant containers used primarily for melting metals, glass, and raw materials, withworking temperatures often exceeding
1700°C

. Their high chemical stability and thermal shock resistance make them essential for lab analysis, sintering ceramic powders, and industrial casting of precious metals, such as gold and platinum.

Alumina ceramic crucible With Lids

Usage: Under normal circumstances most of the material will be analyzed and used to bake saggar made from different materials within the system first and then placed into the crucible or analysis or fired for heating equipment.
According to the speed and heating equipment and temperature characteristics of the product with drawal, some are faster and some are slower.
Because of the crucible and saggar made from different materials with thermal expansion materials.
Crucible easily lead to excessive heating or cooling cracking so it is best to slow down and saggar made from different materials. This will extend the life of crucible and saggar made from different materials.

Specifications:
Cones and arc-shaped, cylindrical, oval, square and rectangular shapes
By the capacity of speakers, from 5 ml to 2000 ml of irregular shape,
Greater capacity can be customised.
