Coupled A1/Si and O/N order/disorder in BaYb[Si4-xA1xOxN7-x] sialon: neutron powder diffraction and Monte Carlo simulations

Coupled A1/Si and O/N order/disorder in BaYb[Si4-xA1xOxN7-x] sialon: neutron powder diffraction and Monte Carlo simulations

The fractions of aluminium, [Al]/[Al+Si], and oxygen, [O]/[O] in crystallographically distinct sites of BaYb[Si4-xAlxOxN7-x] oxonitridoaluminosilicate (space group P63mc, No. 186) were refined based on the results of neutron powder diffraction for a synthetic sample with the composition of x 2.2(2)...
