The crystal chemistry of silica-rich alkali-deficient
Coarse crystals of an extremely silica-rich potassium-deficient nepheline have been synthesized hydrothermally with albite. Electron microprobe analysis yielded the formula 1.76Ko.24Na6.00Al6.24-Si9.76O32. A crystal structure analysis of this nepheline has revealed (1) a disordered Si-Al distribution (2) full occupancy of the smaller cavity site by sodium atoms and (3) the larger cavity is

common form of silica is sand but it also occurs in nature in a crystalline form known as quartz. Pure silica can produce an excellent glass but it is very high-melting (1 723 o C or 3 133 o F) and the melt is so extremely viscous that it is difficult to handle. All common glasses contain other ingredients that make the silica easier to melt and the hot liquid easier to shape.
