Fluorescence of silicates is the main problems when silicates are analysed.
Let us suppose a temperature of T0 ≃ 300 K (a commonly adopted value in many dissolution experiments) and that the main component of silicate is olivine.
We conclude that carbon compounds in impactors are likely to be oxidized by oxygen derived from SiO2, the main component of silicate, within planetary-scale vapor plumes produced by hypervelocity impacts regardless of impact velocity as long as silica is vaporized.
The main components of bioactive silicate glasses are SiO2 Na2O CaO P2O5, having <55%% SiO2 in weight percentage.
Therefore, the addition of nanomagnetite powder did not affect the main hydration products (calcium silicate hydrates and portlandite).
The self-hydration products analyses indicated that the main products were calcium silicate hydrate, calcium aluminosilicate hydrate (C-A-S-H), hydrotalcite, akermanite and calcite.
This type of cement consists of four main components, including Tricalcium Silicate (C3S), Dicalcium Silicate (C2S), Tricalcium Aluminate (C3A), and Tetracalcium Aluminoferrite (C3AF), which give certain functionally to the cement such as enhancing the strength or changing the hydration rate.
This is due to the fact that the quartz reacts with the sodium hydroxide and forms [H2SiO4]2− which is the main component of sodium silicate, and that the K-feldspar has the ability to provide additional alkaline.
Due to thermal treatment, two main crystalline phases: lithium di-silicate and lithium alumina-silicate were obtained in glass ceramic materials.
We assume Mg-bearing glass as the main component of the amorphous silicate core (see Jessberger et al., 1988; Kimura et al., 2003).
