CuO (card number 48-1548)

Bi5Cu3O12 (card number 40-0216)

CuBi₂O₄ (card number 52-1730)

Those who paid the license fee for the database have access. It is not free for all. The folks at ICDD will provide information on a limited number of phases if you ask them. However, I am sure they need to recover their costs for maintaining the database or the it will go away or raise the costs for those of us who subscribe.

Alvena Shahid please reconsider if you should be sharing those files. Did you buy a license or are you sharing from someone else's database?

Muhammad Panachikkool @Warren Straszheim

I previously shared JCPDS information. However, I’ve recently been reminded that these files are part of a licensed database maintained by the ICDD and should not be distributed without proper authorization.

I’ve removed the file to respect licensing terms and strongly encourage others to consult ICDD directly or access the data via institutional subscriptions.

Thank you for your understanding.

Alvena Shahid I am so sorry for the trouble. Thank you for trying to help me.
