Thermal behavior of muscovite sheet mica
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1963 The three spectral types of muscovite sheet mica, i.e., very pink ruby, light green, and dark green, were subjected to heat treatments at temperatures up to 600 °C. The changes in the apparent optic axial angle and in the absorption spectra (0.3 to 15 μ) were studied along with color.
