Mineralogy of Sulfides [PDF]

open access: yesElements, 2017
Metal sulphides are the most important group of ore minerals. As shown in this brief introduction, much is known about their compositions, crystal structures, phase relations and paragenesis. Much less is known about their surface chemistry and, in particular, about their biogeochemistry, and about the formation and behaviour of ‘nanoparticle ...

Synthesis of Sulfide Perovskites by Sulfurization with Boron Sulfides

open access: yesInorganic Chemistry, 2022
Chalcogenide perovskites (CPs), with the general composition ABX3, where A and B are metals and X = S and Se, have recently emerged as promising materials for application in photovoltaics. However, the development of CPs and their applications has been hindered by the limitations of available preparation methods.
