31. The planar process created a flat surface structure protected with an insulating silicon dioxide layer. 32. The smoky colour results from free silicon, formed from the silicon dioxide by natural irradiation. 33. Silicon dioxide acts as a Br�nsted Lowry acid.34. The soil type reflects a mixture of underlying limestone and clay, with very little Silicon dioxide . 35. Current designs use silicon dioxide insulators, which become unworkably leaky in the latest high-speed chip designs. 36. Silicon dioxide ( SiO 2 ) has been used as a gate oxide material for decades.37. The coarse character of the hairs is due to cystoliths of silicon dioxide and calcium carbonate. 38. Chemically, quartz is a compound called silicon dioxide . 39. One process is called thermal oxidation, which forms silicon dioxide on the surface of the silicon. 40. When fiberglass rots I assume the resin is what rots and not the silicon dioxide fiber.
