Abstract

• The stability and the thermo-elastic behaviour of a natural londonite ½1a ðCs0:36K0:34Rb0:15Ca0:04Na0:02ÞR0:91 4eðAl3:82Li0:05Fe0:02ÞR3:89 4eðBe3:82B0:18ÞR4 12hðB10:97Be1Si0:01ÞR11:98O28? has been investigated up to 1,273(3) K (at 0.0001 GPa) and up to 4.85(5) GPa (at 298 K) by means of in situ X-ray powder diffraction. Up to 973 K, no evidence of phase transition or anomalous thermo-elastic behaviour was observed. At T[973 K, londonite shows the first evidence of an irreversible structure destabilisation. The volume thermal expansion coefficient between 298 and 973 K is a0 = 2.38(6)?10-5 K-1. Londonite shows an elastic behaviour up to 4.85 GPa. No phase transition has been observed within the pressure range investigated. P-V data fitted with a second-order Birch-Murnaghan equation of state give V0 = 389.1(1)A° 3 and KT0 = 280(12) GPa. On the basis of the good thermo-elastic behaviour, substantiated by the significantly low compressibility, the modest thermal expansion up to 1,000 K and the significantly high amount of boron (B2O3 * 50wt%), londonite-type materials could be considered as potential inorganic host for 10B in composite neutron-absorbing materials.
