Article
Full-text available
The electronic polarizabilities of most cations, such as Na+, Ca2+, Fe2+, Fe3+, and Zr4+, show a monotonic decrease as the cation coordination increases. However, polarizabilities of the ions [5]Ti4+, [5]V5+, and [6]V5+ show strong deviations from a regular decrease. In this paper we characterize the [5]Ti and vanadyl compounds by infrared frequenc...

Single crystals of ABW-type CsAlTiO4 (CAT), CsFeTiO4 (CFT), CsGaTiO4 (CGT), and ANA-type CsTi1.1Si1.9O6.5 (CST) were grown and characterized by electron microprobe analyses, single-crystal X-ray diffraction, thermal analyses, and spindle-stage optical investigations to determine the electronic polarizability of 4-coordinated Ti⁴⁺, α([4]Ti⁴⁺). The c...
Article
Within the last sixty years, several authors stated that they have synthesized iota-alumina (ι-Al2O3), the hypothetical endmember of the mullite compositional series Al2[Al2+2xSi2−2x]O10-x with x = 1. Iota-alumina is supposed to be a silica-free aluminate having a mullite-like X-ray diffraction pattern. However, no detailed information about its cr...

A single crystal (∼ 20 µm × 20 µm × 330 µm) of mullite-2c, a natural polytype of mullite, was separated from a radially grown cluster of acicular crystals from Ettringer Bellerberg (Quarternary Eifel volcanic fields, Germany). The chemical composition determined from electron microprobe analysis (EMPA) is Na0.01Mg0.05Al8.52Fe0.293+Si3.13Ti0.02O19.5...

Full-text available
It is shown here that the H2O content of hydrous minerals can be determined from their mean refractive indices with high accuracy. This is especially important when only small single crystals are available. Such small crystals are generally not suitable for thermal analyses or for other reliable methods of measuring the amount of H2O. In order to d...
Article
We have evaluated more than 7,000 crystal structures of zeolites in terms of the values of their bond lengths T-O (T = Si, Al, P, Zn, Be, Ge, B, As, Ga, Co) and their variability, as well as the flexibility of their bond angles O-T-O. Out of these known crystal structure descriptions of zeolites we have selected 1179 which have estimated standard d...

POLARIO is a computer program to calculate total electronic polarizabilities, refractive energies, and refractive indices of transparent minerals and synthetic crystalline compounds from their chemical composition and molar volume. If measured refractive indices or observed polarizabilities are entered, POLARIO also allows calculation of the deviat...
Article
Full-text available
Empirical electronic polarizabilities allow the prediction of total mineral polarizabilities and mean refractive indices of the vast majority of minerals and synthetic oxides. However, deviations from the valence-sum rule at cations in some minerals are associated with large deviations of observed from calculated total polarizabilities. We have ide...
Article
Full-text available
This is a comprehensive compilation of refractive indices of 1933 minerals and 1019 synthetic compounds including exact chemical compositions and references taken from 30 compilations and many mineral and synthetic oxide descriptions. It represents a subset of about 4000 entries used by Shannon and Fischer (2016) to determine the polarizabilities o...
Article
The crystal structure and disorder phenomena of Al4B2O9, an aluminum borate from the mullite-type family, were studied using automated diffraction tomography (ADT), a recently established method for collection and analysis of electron diffraction data. Al4B2O9, prepared by sol-gel approach, crystallizes in the monoclinic space group C2/m. The ab in...
