You have synthesized solid electrolytes in the presence of argon. Dispersion in a mill followed by granulation is a continuation of the chemical process. Small particles of the substance are more active in the reaction than normal particles, so you need to continue grinding and granulating in argon.

The answer is yes

So, I need to assemble the pelletiser inside the glove box?

Yes, in the conditions when synthesized

Yes. All your stage most be done in argon condition. Becauos your reaction can carry moisture

Because your substance is sensitive, all reaction related to these material must be done at inert atmosphere for getting high percent of reaction
