A silicon–oxygen tetrahedron is the SiO4 anionic group, or a silicon atom with four surrounding oxygen atoms arranged to define the corners of a tetrahedron. This is a fundamental component of most silicates in the Earth's crust. A variety of silicate minerals can be identified by the way that the tetrahedra links differ, also by the cations present in the mineral. == Silicon–oxygen tetrahedra links == There are five common silicon–oxygen tetrahedra links: # Independent tetrahedra # Single chains # Double chains # Sheet silicates # Framework silicates 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Silicon–oxygen tetrahedron」の詳細全文を読む スポンサード リンク
