Phase diagram applications  

Use phase diagrams when experimenting or researching thermal-barrier coatings, nuclear reactors, photovoltaics, pigments, fuel cells, catalysts, capacitors, transducers, thermoluminescence, molten-salt batteries, photovoltaics, electrolytic refining, and more.


New phase diagram CD content includes:

Oxide and mixed systems with oxides – electrode processing, catalysis, electroceramics, magneto-resistors, thermistors, capacitors, nuclear fuel and nuclear waste, ionic conductors, fuel-cell electrolytes


Chalcogenides – semiconducting sulfides, selenides and tellurides for thermoelectrics, optoelectronics, photovoltaics


Pnictide systems – nitrides, phosphides, arsenides, bismuthides, and antimonides for bandgap-engineered optical materials, electron-transport devices, sensors, detectors, photovoltaics, thermoelectrics

Actinides – (U, Pu, Th)


Actinide-surrogates – (Ce)


Oxycation systems – molybdates and vanadates


Semiconductors – Si, Ge, Sn


Group 3 systems – B, Al, Ga, In, Tl


Salts – including mixed systems with salts


Security update for 4.0 owners  

Version 4.0 utilizes Java for the diagram viewer functionality. The security certificate has recently expired, which will prevent you from viewing diagrams. We apologize for this inconvenience as we work through unanticipated issues encountered with this first release of the all-new PED software. A one-time fix will easily remedy this situation and restore full functionality, but please let us know if you still have trouble viewing. Here’s how to update the Java certificate:

  1. Open Java Configuration
  2. Select the Security tab
  3. Click the “Edit Site List…” button. Click the “Add” button and type the following web address, then click OK: http://localhost:7000 
    1. It will tell you that it isn’t a good idea.  Do it anyway.  There is no risk to your computer.
  4. Click the “OK” button in the Java Control Panel

If you’re having trouble, visit this site for detailed instructions and screen shots.
