1. What does "dry method" refer to and is there any more information that can be given regarding the preparation method? Unfortunately, no other information can be provided regarding the preparation method. Its a trade secret!

2. Does ACS give a classification of the crystal structure of the powder? It is a hexagonal crystal system.

3. Is any information available about specific surface area and bulk density regarding this material? BET was not tested, bulk density is 0.57g / cm³ and tap density is 1.08g / cm³.
