The Silicon-oxygen Structure

There is no reason why, instead of losing its hydrogen, one of the oxygens attached to a silicon cannot attach itself to another silicon. This 

In Fig. XXVI-1 we show the (SiO -4 and (Si207) 6 ions, which are found in ionic crystals, occurring in nature as minerals. The positive ions found associated with them include a variety of metallic ions, such as

Here again the silicon-oxygen structure is continuous and the metallic cations are iaserted according to the requirements of electrical...
