The initial models were refined to R values of 0.06-0.08 , which is rather typical of the determination of the Aurivillius structures from X - ray ( and sometimes neu- tron ) powder diffraction data [ 23 , 24 , 26–28 ] .

The unit cell parameters of the phases were tenta- tively refined by least - squares calculations based on full - profile experimental data using the PowerTool pro- gram [ 6 ] and then ultimately refined using the DBWS- 9411 program [ 7 ] ...
