In order to prepare these beads, a particular process is followed most of the time and it is called as the Stober process. In order to perform this process first a reaction mixture is created while taking water, ethanol as well as catalyst like particles of iron oxide. For this process, the silica precursor is also used. Due to the condensation and hydrolysis of these precursor monomers, silica oxide starts to deposit on the iron oxide. Now you can also avail top quality amine-terminated magnetic silica beads. These are used for a wide range of applications.
