The effect of H2O fluid on relative component mobilities in a bimineralic reaction rim in the system CaO–MgO–SiO2 Joachim, Bastian; Heinrich, Wilhelm; Höschen, Carmen; Abart, Rainer. Gel stoichiometry and the reaction kinetics which control phase evolution are shown to be strongly dependent on the chemical composition of the reaction mix, while the main reaction product is a Na 2 O–Al 2 O 3 –SiO 2 –H 2 O type gel comprised of aluminium and silicon tetrahedra linked via oxygen bridges, with sodium taking on a charge balancing function. In this paper, we report that the NF3/NH3 dry cleaning process using down-flow plasma technique can cause significant surface modification on SiO2 depending on the NF3:NH3 ratio and plasma power of the plasma reaction before (NH4)2SiF6 by-product sublimation step. 2 h2 (g) + o2 (g) → 2 h2o (l) b. n2 (g) + o2 (g) → 2 no (g) c. 2 h2 (g) + o2 (g) → 2 h2o (g) d. h2o (l) + 1/2 o2 (g) → h2o2 (l) e. none of the above Fusion the reaction mixture.
