sorosilikaadiühiku
A sorosilikaadiühik refers to a fundamental structural unit found in certain silicate minerals. Silicates are a major class of rock-forming minerals characterized by the presence of silicon and oxygen in their chemical composition. The basic building block of all silicate structures is the silicon-oxygen tetrahedron, denoted as [SiO4]4-. In a sorosilikaadiühik, two of these [SiO4]4- tetrahedra are linked by sharing one oxygen atom. This sharing creates a distinct structural unit with the formula [Si2O7]6-.
The presence of these linked tetrahedra influences the physical and chemical properties of minerals that contain
