1. The ball milling method consists of balls and a mill chamber. A ball mill usually contains stainless steel container and many balls made up of iron, hardened steel, tungsten carbide or silicon carbide which are made to rotate inside a mill. 2. The powder of material is taken inside the steel container and is converted into nanosize using the ball milling technique. 3.
For the preparation of ZnO nanoparticles both 'mechanical milling' (, Topdown or physical), solgel and autocombustion (, Bottomup or ... jar was then placed in a planetary ball mill PM 400/2 with a speed of 400 rpm for 50 h.
The silica nanoparticles have been prepared by bottomup as well as topdown approach. The bottomup approach is preferably used for the controllable synthesis of ordered SNPs. Solgel method due to its ability to produce monodispersed particles with narrowsize distribution using mild conditions is a frequently used process to synthesize SNPs.
Synthesis of nanomaterials by a simple, low cost and in high yield has been a great challenge since the very early development of nanoscience. Various bottom and top down approaches have been developed so far, for the commercial production of nanomaterials. Among all top down approaches, high energy ball milling, has been widely exploited for the synthesis of various nanomaterials, nanograins ...

A gel is a stiff mass of a continuous phase, more like a viscous liquid. The sol can be prepared by controlled hydrolysis and poly condensation reactions of alkoxides, which then form the network of the resultant glasses. Among the available wet chemical methods, the solgel process is undoubtedly the simplest and the cheapest one.

Nd2Fe14B hard magnetic nanoparticles were synthesized by chemical synthesis techniques. Nd−Fe−B gel was prepared using NdCl3·6H2O, FeCl3·6H2O, H3BO3, citric acid, and ethylene glycol (EG) by a Pechini type sol−gel method. This gel was subsequently annealed to produce mixed oxide powders. Nd2Fe14B nanoparticles were prepared from these oxides by a reduction−diffusion process.
