Silicon wafers have been utilized richly in microelectronics and MEMS as a stage for manufacture. A fascinating variety of the standard Diced silicon wafer with a dry oxide coating is the SOI substrate. To deliver these wafers, two silicon wafers are reinforced together, utilizing silicon dioxide of around 1�2 �m thickness as a bond layer. One of the silicon wafers is weakened to a thickness of 10�50 �m.

Most of these strategies of iron oxide beads coated with silica incorporate a pretreatment step in which the outside of iron oxide particles is altered in a way that expands their strength in fluid arrangements. Here we propose that by diminishing the underlying centralization of the impetus for a brief period to limit nucleation by decreasing forerunner hydrolysis rate and afterward steadily expanding the fixation to the ideal level to permit silica arrangement to continue typically it might be conceivable to forestall total without surface change.
