Ball mass is an important parameter that is known to have an influence on the outcome of a mechanochemical reaction induced by ball milling. A standard way of modifying the ball mass is to change the size of the ball made of the same material. In this case however a change in mass is accompanied by a simul Editor's Collection Mechanochemistry The Solid State of

2022 4 1 The influence of the piezoelectric effect on the degradation efficiency is investigated by using Rh B as a target degradation pollutant and a planetary ball mill is used as an excitation source in which different revolving speeds of 200 400 and 600 rpm are set Fig. 4 a 4 d . The degradation can be neglected when there is without CBO under 200 rpm however the

A vibrating frame grinder has been instrumented for evaluating the amplitude and frequency of ball oscillation as a function of the amplitude of vibration of the frame and of the ball mass. Based on such measurements it is found that Ni x Zr y compounds become fully amorphized provided the specific milling intensity is greater than a temperature and composition dependent

I. INTRODUCTION BALL milling has been used to induce chemical reactions and alloying in a variety of powder mixtures. The process is called mechanochemical synthesis when applied to the preparation of inorganic or organic materials. 1–5 An especially promising application is mechanical alloying whereby oxide dispersion strengthening atomic level alloying and

The ball milling induced reduction of MoS2 by Al has been investigated. Although this is a highly exothermic reaction that based on its thermodynamic properties should progress as a self sustaining process ignition could not be achieved by ball milling. In order to identify the reason XRD particle size distribution SEM and DTA measurements were carried out on a series of
