21. Oxidised silicon is quartz, i . e . silicon dioxide , the primary component of glass. 22. Iron and silicon dioxide together also act as a catalyst for formation of the structures. 23. The oxide growth rate is limited by the diffusion of the oxidants through silicon dioxide . 24. Obsidian consists mainly of SiO 2 ( silicon dioxide ), usually 70 % or more. 25. The oxygen in the water molecule reacts within the silicon wafer to form silicon dioxide . 26. Silicon dioxide is acidic, and thus the alkali metal hydroxides can also attack silicate glass.27. We will consider an example of a MOS capacitor based on silicon and silicon dioxide . 28. Egian would not identify the brand name, source or amount of the silicon dioxide delivered. 29. The oxidation of silicon during this stage occurs at the silicon / silicon dioxide interface. 30. Filamentous carbon can also form when acetylene decomposes on films of palladium and silicon dioxide .
