A new technique for specimen preparation of metal or ceramic powders for transmission electron microscopy (TEM) is presented. The powders were dispersed into ductile metal powders such as Al or Cu etc., which easily agglomerate to fragments or balls when submitted to ball milling. Specimens are then easily obtained from these agglomerates using conventional TEM specimen preparation methods. The procedure was shown to be a versatile means of obtaining accurate and representative specimens of powders for TEM.
