Preparation of molecular alloys by the ball-milling technique

Ball milling is a technique used extensively in metallic powders to obtain adequated properties for their applications. In this study we show that this technique is also useful for preparing organic molecular alloys. Pentaglycerin/Pentaerythritol alloys have been obtained mechanically at room temperature. Calorimetric and crystallographic characterizations establish that the mechanically obtained alloys have the same solid crystalline structure and transform to the plastic phase as the conventionally prepared alloys from the melt of the pure compounds.
