WebA novel precipitation mechanism of CCSH phases was hypothesized, where crystals precipitated directly from solution when Ca2+ ions react with polymerized, aqueous silica. Direct precipitation was found to be dependent on the dissolution rate of the reactants, the concentration of NaOH, the starting phase of CO2 (gas vs carbonate salt), and time. WebCrystalline silicon or ( c-Si) Is the crystalline forms of silicon, either polycrystalline silicon (poly-Si, consisting of small crystals), or monocrystalline silicon (mono-Si, a continuous crystal ). Crystalline silicon is the dominant semiconducting material used in photovoltaic technology for the production of solar cells.
