摘要: Binary calcium aluminate glasses containing 59–70 mol % CaO have been formed, as a series of in which CaF2 replaces CaO. The transformation range viscosity and glass temperature the binary decreases concentration increases, whereas thermal expansion coefficient, refractive index, infrared cutoff wavelength increase. substitution for results decrease viscosity, temperature, an increase coefficient electrical conductivity, no detectable change wavelength. Magic angle spinning nuclear magnetic resonance indicates that aluminum ions these are tetrahedral coordination. These will be discussed terms structures glasses.
