Improved compression properties of propyphenazone spherical crystals.

Spherical propyphenazone crystals were produced by an agglomeration technique using a three solvents system. After selecting the best propyphenazone solvent (ethyl alcohol), non-solvent (demineralized water) and bridging liquid (isopropyl acetate), several of their ratios were tested by a Sheffé ternary diagram. Micromeritic properties of agglomerates such… (More)
