Ball Milling an overview ScienceDirect Topics
Ball milling technique, using mechanical alloying and mechanical milling approaches were proposed to the word wide in the 8th decade of the last century for preparing a wide spectrum of powder materials and their alloys In fact, ball milling process is not new and dates back to more than 150 years It has been used in size comminutions of ore, mineral dressing, preparing talc powders and many During the last decade numerous protocols have been published using the method of ball milling for synthesis all over the field of organic chemistry However, compared to other methods leaving their marks on the road to sustainable synthesis (eg microwave, ultrasound, ionic liquids) chemistry in ball mills is rather underrepresented in the knowledge of organic chemistsBall milling in organic synthesis: solutions and In this paper, to improve the poor wettability between the Carbon nanotubes (CNTs) and metal matrix, the mechanical alloying (MA) technique by the ball milling method was employed Also, the CNTs were precoated to improve the agglomeration of the CNTs with copper powder The main aim of this work i Synthesis of CuCNT nanocomposite powder by ball
