Process for making silver metal filaments

A process for making silver metal particles from silver salt particles having the same morphology, comprising the steps of:

• a) providing precursor silver salt particles selected from the group consisting of silver acetate end silver sulfide having a selected morphology;
• b) containing said precursor silver salt particles in a reactor vessel having means for supporting said particles in an air suspension to prevent the agglomeration of said particles;
• c) flowing air through said reactor vessel at e flow rate sufficient to suspend said particles in said reactor vessel;
• d) heating said suspended precursor silver salt particles simultaneously with said flowing step to a processing temperature and at a heating rate below which physical deterioration of said suspended precursor silver salt particles takes place;
• and
• e) maintaining said suspended precursor silver salt particles at said processing temperature for a period of time sufficient to convert said particles into silver metal particles having the same morphology as said precursor silver salt particles.
