Mgm. Vandervis et al., THE THERMODYNAMIC PROPERTIES OF TETRAETHOXYSILANE (TEOS) AND AN INFRARED STUDY OF ITS THERMAL-DECOMPOSITION, Journal de physique. IV, 3(C3), 1993, pp. 75-82
A review is given on the determination of the thermodynamic properties
of Si(OC2H5)4 (TEOS, tetraethoxysilane). In addition, the thermal dec
omposition of TEOS has been studied by in-situ IR spectroscopy. The de
composition products in the gas phase in the absence of oxygen are org
anic fragments (ethanol, ethanal, ethene, methane, carbon monoxide), a
nd in the presence of oxygen water, carbon dioxide, ethanal and methan
al. The results are compared with thermodynamic equilibrium calculatio
ns and kinetic models.
