Abstract
Using a synchrotron radiation source and a diamond anvil cell, we measured the pressure dependence of the lattice parameters of a recently discovered phase,
Ta
4
Al
C
3
. This phase adopts a hexagonal structure with the space group
P
6
3
∕
mmc
; at room conditions, the
a
and
c
parameters are 3.087(5) and
23.70
(
4
)
Å
, respectively. Up to a pressure of
47
GPa
, no phase transformations were observed. Like
Ta
2
Al
C
, but unlike many related phases such as
Ti
4
Al
N
3
,
Ti
3
Si
C
2
,
Ti
3
Ge
C
2
, and
Zr
2
In
C
, the compressibility of
Ta
4
Al
C
3
along the
c
and
a
axes are almost identical. The bulk modulus of
Ta
4
Al
C
3
,
261
±
2
GPa
, is
≈
4
%
greater than that of
Ta
2
Al
C
. Both, however, are
≈
37
%
lower than the
345
±
9
GPa
of TaC.
