Аннотация: The Platinum-group elements (PGEs) are of significant technological importance. PGEs are used primarily in industrial applications (e.g., catalysts) and have become widely established in chemical, electrical, and electronic engineering. The PGEs and the compounds they form have attracted considerable attention in recent years due to their specific properties and their application in new technologies. They exhibit various interesting physical, chemical, and structural properties that place these compounds at the interface of chemistry, mineralogy, solid-state physics, and material science. Therefore, there is still a demand for exploration and mining and to advance the understanding of the natural process that lead to their formation. This chapter consolidates the experimental methods that can be applied for the synthesis of PGE compounds. Dry synthesis and the major experimental methods used to try to obtain single crystals are summarized and some examples of the synthesis of PGE phases are discussed. A list of approved platinum-group minerals (PGMs) recognized up to the end of 2016, is presented with a focus on newly-named minerals and their experimental aspects. The up-to-date list of recognized PGMs is given in Tables 10.110.3. This chapter is written to encourage the application of experimental studies for a better understanding of PGM, their formation and occurrence under natural conditions. The available knowledge is often dispersed across the chemical, physical, mineralogical, and metallurgical literature. Additionally, there is often an information gap between investigations of synthetic systems and those of natural minerals. A number of PGE-bearing compounds have been determined and studied due to their specific (e.g., electrical or electrochemical) properties rather than their mineralogical significance.
