title: Influence of crystal form on tensile strength of compacts of pharmaceutical materials.
abstract: The tensile strengths of compacts of different crystal forms of aspirin, sulfathiazole, and barbital were determined with a modified tablet hardness tester. For each material, the tensile strength could be correlated with the amount of plastic flow and/or crushing undergone by each crystal form during compression.
