Molecular dynamics simulation of binary CaO–FeO, MgO–SiO2, FeO–SiO2, CaO–SiO2 and ternary CaO–FeO–SiO2 systems

Thermochimica Acta, 2001
Abstract Molecular dynamics models of binary CaO–FeO, MgO–SiO 2 , FeO–SiO 2 , CaO–SiO 2 and ternary CaO–FeO–SiO 2 systems were constructed at 1873 K using the Born–Mayer pair potentials. The potentials included the effective dipole–dipole interactions for Ca–Fe, Mg–Si, Fe–Si and Ca–Si pairs.

Raman spectra and structure of BaOSiO2 SrOSiO2 and CaOSiO2 melts to 1600°C

Chemical Geology, 1995
Abstract Raman spectra were collected for barium silicate, strontium silicate and calcium silicate melts at temperatures ranging from the glass transition region to temperatures as high as 1600°C. For melts less polymerized than disilicate, the spectra were used to determine the relative abundances of the Q3, Q2 and Q1 tetrahedra and the Si2O52 ...

Rheological behaviour of solutions affording SiO2 and SiO2/ZrO2 fibers

Journal of Non-Crystalline Solids, 1991
Abstract The rheological behaviour of solutions composed of silicon ethoxide (TEOS) or of TEOS and zirconium propoxide (TPOZ) in various ratios are studied as a function of hydrolysis conditions, concentration of acetylacetone, addition of dimethyldiethoxysilane (DEDMS) and nature of solvent.

Charge Trapping in SiO2

AIP Conference Proceedings, 1984
Avalanche injection techniques are extensively used to inject electrons and holes from silicon into the thin SiO2 layer of the type used in MOS transistors. This makes it possible to evaluate the electron and hole trapping kinetics in this material using only simple MOS devices.

Hydrogen chemisorption and mobility on Ru/SiO2, K/Ru/SiO2 and Ru-Ag/SiO2

1996
Abstract Microcalorimetry and 1 H NMR have been used to investigate hydrogen chemisorption on Ru/SiO 2 , K/Ru/S1O 2 and Ru-Ag/SiO 2 . Adding small amounts of K or Ag to Ru/SiO 2 significantly reduces the amounts of hydrogen adsorbed and eliminates intermediate (~50 kJ/mole) as well as weakly bound states ( 2 .
