Vapor Pressure Data - Selection-Guides -

The following table contains general recommendations of suitable crucible/source combinations for the most commonly used evaporation materials. These recommendations base on scientific knowledge partly verified and amended by our own experience and customer feedback.

Where more than one source or crucible are suggested for particular evaporants, the choice has to be made based on the specific requirements of the customer’s application. Please inquire in case of doubt.

Important note: Due to the great diversity of applications and system conditions, we take no responsibility for the correctness of the suggestions below.
The values in the table below are quoted from, respectively calculated on the basis of “Karlsruher Nuklidkarte” by Magill, Pfennig, Galy and the IUPAG Periodic Table of Elements. We take no responsibility for the correctness of the given values.
