Ballmill perovskite

Mar 01, 2019 Thus, ball milling reactions cannot be safely assumed to proceed at room temperature, unless the temperature inside the ball mill is being actively monitored. In spite of all the benefits of synthesizing halide perovskites by solid-state methods compared to solution methods, solid-state methods are so far incompatible with film fabrication
