抄録

On the basis of a TTT diagram during solidification of a melt in the system SiO2-Al2O3-MgO-MgF2-K2O-B2O3, the effect of the heat treatment conditions on grain size, morphology and crystallization degree of fluor-phlogopite is discussed. By isothermal heat treatment in the range 1253 to 1473 K, fluor-phlogopite as spherical grains was crystallized directly from a supercooled liquid. Below 1253 K, spinodal decomposition-type phase separation occurred as a prelude to crystallization. Energy dispersive X-ray analysis suggested that the growth rate was controlled by diffusion of Mg ions. A linear relationship between the spinodal wave length and the plate diameter was obtained.
