Figure 3.1.1: The silica tetrahedron, the building block of all silicate minerals. (Because the silicon ion has a charge of +4 and the four oxygen ions … WebThe tectosilicates or framework silicates have a structure wherein all of the 4 oxygens of SiO 4-4 tetrahedra are shared with other tetrahedra. The ratios of Si to O is thus 1:2. Since the Si - O bonds are strong covalent bonds and since the structure is interlocking, the tectosilicate minerals tend to have a high hardness. new vision tv uk
