The potential involvement of polysulfide radical anions S n•− is a recurring theme in
discussions of the basic and applied chemistry of elemental sulfur. However, while the …

This review contains data on a wide class of microporous materials with frameworks
belonging to the sodalite topological type. Various methods for the synthesis of these …

The isomorphism of S-bearing feldspathoids belonging to the cancrinite, sodalite, tugtupite,
vladimirivanovite, bystrite, marinellite and scapolite structure types has been investigated …

Bystrite is redefined as a four-layer cancrinite-group mineral with the four-layer Losod-type
framework and the end-member formula Na7Ca (Al6Si6O24) S52–Cl–. The mineral is …

Surface heterogeneity of minerals can significantly affect the adsorption of collectors.
Petroleum sulfonate is widely used as a fluorite collector, but how the surface heterogeneity …

Two sodalite samples (sample I is Na8Al6Si6O24Cl2⋅ 0.4 H2O from the Kovdor alkaline
ultramafic massif with carbonatites in the Murmansk region, Russia, and sample II is …

Crystal-chemical features of a sulfide-bearing variety of the cancrinite-group mineral
balliranoite from the Tuluyskoe lapis lazuli deposit, Baikal Lake area, Siberia, Russia, have …

Lazurite and other lazurite-related minerals (LRMs) containing sulfur in both sulfate and
sulfide forms are sodalite-type compounds with various extraframework species, of which …

It is known that various polysulfide species determine the color of sodalite‐group minerals
(haüyne, lazurite, and slyudyankaite), and that heating induces their transformations and …

New data on the crystal structure and isomorphism of extra-framework components in the
cancrinite-group mineral tounkite have been obtained using chemical and single-crystal X …
