How to choose evaporation boat

Date of release:2019-01-10 Author: Click:

How to choose evaporation boat and tungsten-molybdenum crucible in the process of coating is one of the problems often encountered in the coating work of tungsten crucible manufacturers.


This document describes the properties of various materials, including density, melting point, evaporation temperature, selection of evaporation boat, selection of crucible for electron beam evaporation, and precautions for coating.


The evaporation boat is the most widely used evaporation source because of its simple structure and convenient use. Commonly used materials are tungsten, molybdenum, tantalum, niobium, graphite, conductive boron nitride and other conductive ceramic materials. Tungsten, molybdenum and tantalum are brittle due to recrystallization when heated to high temperature.


Crucibles include tungsten crucible, molybdenum crucible, tantalum crucible, copper crucible, graphite crucible, alumina crucible, conductive boron nitride crucible and quartz crucible.


The data and contents in this paper refer to many books, together with the author's personal experience, for reference only. If you have any questions or questions, please contact the author. We will update it.


The characteristics of another compound and the selection of evaporation boat and crucible will be introduced later. We look forward to helping you with your work.
