ABSTRACT:
The phosphorus effusion cell arrangement according to the present invention comprises a first vacuum container for red phosphorus, a second vacuum container for white phosphorus, said first and second vacuum containers being interconnected, means for providing vacuum, a thermal cracker in connection with said second vacuum container, as well as a control valve between said second vacuum container and said thermal cracker. The present invention is characterized in that it further comprises a separating valve between said first and second vacuum containers, provided that there is no direct connection between said first vacuum container and said thermal cracker. The invention also relates to a method for producing molecular phosphorus P2.
