...Dušan Radusinović; Cvetko Markov Abstract Macedonite, PbTiO 3 , occurs as tiny grains and crystals in the amazonite quartz syenite veins in Crni Kamen near Prilep, Macedonia, Yugoslavia. It is tetragonal: a, 3.889 ± 0.024 Å; c 4.209 ± 0.036 Å. The strongest X-ray powder diffraction lines are (Å...

... compositions) minor macedonite. Electron microprobe analyses of the hollandites indicate that there is a continuous series of compositions between the two hexatitanate end-members, Ba(Ti 6 Fe 2 3+ )O 16 and Pb(Ti 6 Fe 2 3+ )O 16 . The crystal structure of one intermediate member was refined by the Rietveld...
