WebFigure 10.38 (a) Silicon dioxide, SiO 2, is abundant in nature as one of several crystalline forms of the mineral quartz. (b) Rapid cooling of molten SiO 2 yields an amorphous solid known as “fused silica”. Crystalline solids are generally classified according to the nature of the forces that hold its particles together. These forces are ...
