Nesosilicates
The nesosilicates (orthosilicates of many authors) are characterized by the presence of [SiO4]4– tetrahedra that do not share any of their four... -
Crystal Structure of Oxide Ceramic Coatings Obtained On Alloys with High Silicon Content
Crystal structure of oxide ceramic coatings obtained on AK9M2 and AK12 alloys is determined. Already after 5 min of processing the AK9M2 alloy by...

Inosilicates
Inosilicates are also known as chain silicates because of the corner-sharing chains of silicate tetrahedra along z-direction. Apices of adjacent... -
Sorosilicates and Cyclosilicates
When two silicate tetrahedra are linked with each other via a bridging oxygen an [Si2O7]6– oxyanion results. The presence of osxyanion does not... -
Naturally occurring van der Waals materials
The exfoliation of two naturally occurring van der Waals minerals, graphite and molybdenite, arouse an unprecedented level of interest by the...
-
Phyllosilicates
The basic unit of silicates, silicon tetrahedron, is linked to other tetrahedra by sharing all three basal oxygens in such a cyclic manner that these... -
Oxygen Solubility in Ni–Co Melts at Complex Deoxidation with Aluminum and Silicon
AbstractNi–Co alloys are broadly used in various industries. One of the harmful impurities in these alloys is oxygen, which is found in metals in...
