Causes of anomalous mineralogical diversity in the Periodic Table
Mineralogical magazine, 2015When crustal abundance (A, measured in atomic parts per million) of a chemical element is plotted vs. number of mineral species in which that element is an essential constituent (S), a significantly positive correlation is obtained, but with considerable

Thermal and thermodynamic data concerning the selenites from group IB in the periodic table
Thermochimica Acta, 1984Abstract The thermal dehydration of CuSeO 3 ·2 H 2 O, and the thermal dissociation of CuSeO 3 and Ag 2 SeO 3 are studied. The mechanism of these processes is suggested. The heats of phase transitions and the specific heats of the corresponding compounds are determined.

In the process of research [1], a study was made of electrical conductivity of polycrystals of the nitrites of lithium, sodium, potassium, rubidium, and cesium, as a function of temperature from −150 °C to their melting points: 222, 438, 283, 422, and 400 ° C, respectively.

Gas chromatography of chlorides and bromides of III-, IV- and V-group elements in the periodic table [PDF]
Fresenius' Zeitschrift f�r Analytische Chemie, 1975 The theory for the relation between retention volume and boiling point in gas chromatography was applied to the retention volumes for bromides of IV- and chlorides and bromides of III- and V-group elements in the periodic table, as an extension of the previous paper on chlorides of IV-group elements.
