Abstract

Single crystals of lead aluminosilicate hollandite, with composition Pb_0.8Al_1.6Si_2.4O₈, have been synthesized at 16.5 GPa and 1450°C. Crystals are tetragonal [space group I⁴, Z = 2, a = 9.414(3), c = 2.750(3) Å, V = 243.7(3) Å³]. Si and Al are disordered on the octahedral site. Pb is best modeled by two atom sites, one on the fourfold axis and the other split, lying off the fourfold axis. -from Authors
