Description and Uses
Barium nitride purportedly has the molecular
formula of Ba3N2 and the molecular weight of
439.9944 g/mol. Its CAS number is 12047-79-9. It is
offered for sale by several reputable manufacturers but
the actual composition and identity may not coincide
with the formula presented. Although Mg, Ca (and to
some extent Sr) forms a number of compounds based
upon the general formula M3N2, there is no report in
the literature that or Ba forms such compositions. The
literature is devoid of any data relating to Ba3N2 and
the subnitride is mentioned only in the presence of Sr2N.
Barium nitride has been reported to be metastable
and sublimes in the 915 to 1050 C temperature range.
The reported equation for this behavior is: log
P = 6.38 × 104/T(K) and it decomposes when heated
beyond this range to form the metal and nitrogen gas,
i.e. it is metastable. Thus, the existence of barium nitride
is doubtful and no report of its formation or properties
exists to date.
Barium nitride is a ceramic that finds use as a dopant in optical materials such as white emitting LEDs. Ba3N2 is also used as a synthetic precursor for ternary metal nitrides and as a flux growth medium for GaN.
