The experiments have been carried out under the conditions of 0.75 M, 0.5 M and 0.25 M NaOH solutions; solid/liquid ratios of 1/60 and 1/80; 150 ℃, 180 ℃ and 210 ℃; and vapor pressures. Experimental results show that the amount of nuclei versus time plots manifest a normal distribution curve. The concentration of dissolved glass in the solution increases with time until it attains the maximum where the amount of analcime nuclei reaches its maximum as well. Under high dissolution conditions, the solution concentration will attain its maximum when the dissolution is near complete, and nucleation will occur no more when the solution concentration drops to a steady state. To the contrary, the solution concentration will attain its maximum before complete dissolution, and nucleation will not happen any more when the solution concentration drops to steady state at complete dissolution under slow dissolution conditions.application/pdf18082 bytesapplication/pdfzh-TW國立臺灣大學地質科學系暨研究所reporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/11723/1/882116M002021.pdf
