Authors: HUFFMAN M. , NAVROTSKY A. , PINTCHOVSKI F. S. 
Published: May 2016

AbstractTwo kinds of low pressure CVD SiO2 samples, heterogeneous film and homogeneous powdery deposit ("snow"), have been collected on stainless steel at three different deposition temperatures: 523, 643,and 703 K. Both film and "snow" samples are metastable (in terms of enthalpy relative to bulk SiO2 glass) by up to 101 kJ mol′ l. The excess enthalpy increases with decreasing deposition temp. and gradually disappears on annealing at high temperatures.
