Hydrothermal Nanotechnology: Putting the Last First
Exploring the Realms of Nature for Nanosynthesis. Chapter. Hydrothermal Nanotechnology: Putting the Last First Bochenek et al. prepared BFN nanoceramics by high-energy ball milling. After 20 h of milling of the mixture of the starting powders pure BFN perovskite phase has been recorded. As the flowchart depicts BaO Ball milling enhances energy efficiency and also avoids toxic solvents/reagents (Xu et al., 2019). Such reactions along with microwave assistance do not require the influence of solvents and are also processed at ambient conditions. As it is simple and eco-friendly, this ball milling technique can also be represented as a greener A focus to green synthesis of metal/metal based oxide

Synthesis of nanomaterials using various top-down and
Mechanical milling or ball milling process of top-down techniques. The simplest and efficient mechanical process of the top-down approach is ball milling, which produces NPs by attrition. It is the process of transferring kinetic energy from the grinding medium to the material being reduced. A variety of NPs and metal alloys are created Wet ball or attrition milling techniques can be used for the synthesis of homogeneous powder mixture. Al 2 O 3 /SiC composites are widely prepared by this conventional powder mixing route by using ball milling [70]. However, the disadvantage in the milling step is that it may induce certain pollution derived from the milling media. Synthesis of Nanocomposites ScienceDirect
