Mechanochemistry using ball mills is a promising technique with applications in organic and inorganic chemistry as well as material sciences 14.During ball milling, up to 80 of the energy that is generated in the mill is dissipated as heat.This is why measurement and control of the temperature in the ball mills is important, for example, if heat-sensitive products are formed that.
It is shown that mechanical treatment in a ball mill leads to a decrease in the defects level, an increase in the curie point and a demagnetizing factor of ferrite ceramics.The growth of the demagnetizing factor is associated with an increase in the porosity of ferrite ceramics samples pre-grinded in ball.
