Which of the following statements regarding soda glass is incorrect? The modifying cations break the tetrahedral silicate network and make it easier to form glass objects Soda glasses are utilized for flat glass and hollow glass products The modifying cations occupy interstitial spaces in the silicate network Soda glasses contains mixtures of alkali and alkaline earth oxides that result in much more stable glasses than alkali silicates alone The modifying cations lower the melting point and increase the viscosity of the glass

Crystal Lattices and Unit Cell

Consider a crystal. The regular and repeating pattern of constituent particles is the most distinguishing feature of crystalline solids. A crystal lattice is formed when these particles are replaced with representative points. The three-dimensional arrangement of constituent particles is known as a crystal lattice. Unit cell is that the smallest portion of a space lattice which when repeated in several directions, generate the whole lattice. Unit cell is a building block of a lattice. It is the smallest unit of cell.
