Welcome to a database that provides thermochemistry
for gas-phase and condensed species relevant to a wide range of
high-temperature processes, including chemical vapor deposition (CVD),
chemical vapor infiltration (CVI), catalysis, combustion, materials
corrosion, and aerosol processing. Thermochemistry is the foundation
for understanding chemical reactions and as such is essential to the
development of predictive models for many high-temperature processes.
The database includes thermodynamic data (heats of formation, enthalpies,
entropies, and heat capacities) for gas and condensed-phase species,
thermodynamic models for specific condensed-phase material systems that
account for non-ideal behavior in those systems, and a wide range
of calculated molecular properties for gas-phase species.

The database is an expanding document.
Data for additional compounds will be added periodically and we will post
a notice whenever the website has major additions.
We strongly encourage
join mailing list
for two reasons:
1) to be notified
automatically of any major additions and 2) to be alerted if any modifications
are made to existing data or any problems are discovered.
Your email address will not be provided to anyone unconnected
with the database, and we do not anticipate sending more than a few emails per year.
Questions and comments regarding the database can be sent to
