Evaporation Boats

   

The tungsten, molybdenum, tantalum evaporation boats have a high melting point, good electrical conductivity and low vapor pressures. These charcterissitics make them as the excellent evaporation source for materials evaproation.  Due to the low vapor pressure of our boats, there is no tungsten, tantalum and molybdenum particles will enter the vapor or contaminated the evaporation materials during application.  AEM provides high qulaity evaporation boats with customized sizes.

Applications of Evaporation Boats

1. As a container, evaporation boats are used for the analysis of materials and products;
2. Designed for burning solid materials.

Precautions to Use of Evaporation Boats

1. Put the items that need to be analyzed then heat them into the crucible or sagger;
2. The heating temperature increase and decrease are according to the characteristics of equipment and products;
3. Too quick heating or cooling will lead to cracking of the evaporation boat. The best way is slowing down the heating process, which can prolong the life of combustion boats.
