Glass transition temperature studies of planetary ball milled glasses: Accessing the rapidly cooled glassy state in Na4P2S7-xOx, 0 ≤ x ≤ 7, Oxy-thio phosphate glasses
Source abstract
Abstract
Abstract This report details the very first in-depth study of the glass transition temperature (Tg) for planetary balled milled (PBM) Na4P2S7-xOx (NaPSO), where 0 ≤ x ≤ 7, glasses. For 0 ≤ x ≤ 5, fully amorphous, homogeneous, and chemically reacted compositions can be prepared. For samples with 5 5, both Tg and Tc decrease sharply, becoming nearly identical at x = 7 where glass formation essentially ceases. For smaller values of x, Tc increases with both chain length and the structural complexity of the composition but decreases sharply for glass-ceramics of x > 5.
