Preparation
To prepare trilithium phosphide, Li and red P are
fused in a crucible made of zirconium dioxide and lined with LiF. The crucible is hermetically sealed in an iron
crucible and heated to 680°C.
Very pure red-brown Li3P is obtained.
It is transferred from the crucibles to glass vessels provided with
ground stoppers and stored under Ar. The product should not
come in contact with air at any time.
