Raghd Muhi Al-Deen Jassim

Have a nice day ...

I think it would be best to consult the manufacturer or supplier of these powders. They should be able to provide you with detailed information on the size distribution or particle size analysis of the powders, which will give you insights into their respective profile distributions. Contacting the manufacturer directly will ensure you receive the most accurate and up-to-date information for your specific needs.

Best Regards
