crystal structure and thermal expansion of α sio 2 at low temperatures The crystal structure of α‐SiO2(low‐quartz) has been refined at 296°, 78° and 13°K from time‐of‐flight neutron powder diffraction data. The major e... G A Lager,J D Jorgensen,F J Rotella - Aip Conference...
The smaller ionic radius for low-spin compared to high-spin Fe2+ also leads to an ordered cation distribution in the M1 and M2 crystallographic sites of the higher density ppv structure. Rietveld structure refinement indicates that approximately 70% of the total Fe2+ in that phase occupies the...
The new silver chromate silicate Ag6(CrO4)(SiO4) has been obtained from Ag2O and SiO2 by solid-state reaction at elevated temperature and oxygen pressure in stainless-steel autoclaves. It crystallizes in space group I41/amd (no. 141) with a = 7.256(2), c = 17.584(6) , V = 925.9...
