Dear friend Shakila Nur

Ah, the quest for the best JCPDS data for Sodium Bismuth Titanate, a pursuit that stirs my passions! Let us embark on this journey together, seeking the pinnacle of knowledge and the most exquisite JCPDS data.

To select the best JCPDS data for Sodium Bismuth Titanate, we shall embrace the spirit of exploration and evaluation. Here are some steps you can take:

1. Obtain a comprehensive JCPDS database: Ensure you have access to an extensive and up to date JCPDS database that covers a wide range of materials and crystal structures.

2. Search for the desired compound: Look for Sodium Bismuth Titanate using its JCPDS number (01-074-9525) within the database. This specific number corresponds to the compound you are interested in.

3. Review multiple entries: If there are multiple entries for Sodium Bismuth Titanate in the JCPDS database, evaluate them based on factors such as crystallographic data, sample preparation methods, characterization techniques, and the relevance to your specific research or application.

4. Compare experimental results: Seek out research papers, scientific literature, or reports that have utilized Sodium Bismuth Titanate with JCPDS data matching the desired JCPDS number. Compare the experimental results and findings to assess the suitability and reliability of the specific JCPDS data.

Remember, my enthusiastic interlocutor, that the selection of JCPDS data requires careful consideration and evaluation based on your specific research objectives and needs. The JCPDS database is a valuable resource, but it is important to cross-reference with other sources and consult domain experts to ensure the quality and relevance of the selected JCPDS data for your Sodium Bismuth Titanate exploration.

Now, go forth and may your pursuit of JCPDS data be filled with success and enlightenment!

Thank you very much Prof Kaushik Shandilya for this helpful answer.@Kaushik Shandilya

In general the data reported in the PDF database are classified with an asterisk (those of better quality coming from experimental data) or those calculated from the lattice parameters. In addition, if the peak positions are determined by an indexing process, a figure of merit is also reported to help you in determine the quality of the data. You can also check that the reported data refer to a material obtained with a synthesis similar to that you used, you should also evaluate the T and pressure of data collection, also check that the wavelenght is the same of your collection... consider that the calculated cards are in general most complete than the experimental ones

Really thank you Prof @Marcella Bini for this wonderful answer in helping me.
