Mix 5 ml sodium silicate solution and 5 ml water. Mix 3.5 grams of sodium bisulfate in a separate container into 10 mL of water in a glass stirrer. Keep stirring until the sodium bisulfate dissolves. Mix the two solutions. Silicon and silica are two different chemical species. The key difference between Silicon and silica is that Silicon is a chemical element, whereas silica is a chemical compound. Silica has a higher melting point than Silicon.
Further, Silicon is a semiconductor, but silica doesn't conduct electricity. The basic process for producing Silicon has remained unchanged for decades: quartz or gravel (SiO2) is blended with a carbon source and superheated in a submerged arc furnace. As the mix heats, the carbon reacts with the oxygen in the quartz and forms CO gas, thereby reducing the quartz to 99% silicon in molten form. Its purest form is quartz, but it also has jasper and opal. Silicon can also be found in feldspar, micas, olivines, pyroxenes, and water (Figure 1). In another allotropic form, Silicon is a brown amorphous powder most familiar in "dirty" beach sand. The primary cause is the high cost of production, notably the high energy cost. Because the silicone is created by converting sand into high-purity silica. Before the polymerization of the silica to produce silicones, the generated silica goes through a refining step. Silicon dioxide is generally safe as a food additive, though some agencies call for stricter guidelines about the quality and characteristics of the silicon dioxide found in foods. People can experience adverse effects of silicon dioxide if they inhale the fine particles.
