Hydrothermal Alteration of Glass to Chrysotile [PDF]
Journal of the American Ceramic Society, 2012 Chrysotile fibers were synthesized from glass in hydrothermal conditions. The starting materials were first held at 1650°C and then rapidly quenched down to room temperature. The resulting glass, after the addition of mineralizing agents, was hydrothermically altered in the following conditions: temperature 300 °
