Description and procedure to access databases
This is a portal to a series of forms-based calculators for retrieving thermodynamic properties of endmember phases and reactions between phases. You may also calculate the location of univariant reactions in temperature-pressure space. This functionality is supported using server-side PHP scripts that query a MySQL database of property tables; calculations are performed using web services documented elsewhere on at this site. These web services are available for use on your own web pages or in applications that consume web services, like Microsoft™Office.
At the present time only the Berman (1988) database is online. As time and resources permit, additional databases will be activated. We could use some assistance with this effort, and if you are interested in helping, please contact us.
To access a specific calculator choose an internally consistent thermodynamic database from the table below by clicking "Go To" in the Select column (NYI indicates that the service is not yet implemented):
