Sol–gel process - Wikipedia
The Stöber process is a well-studied example of polymerization of an alkoxide, specifically TEOS.The chemical formula for TEOS is given by Si(OC 2 H 5) 4, or Si(OR) 4, where the alkyl group R = C 2 H 5. Alkoxides are ideal chemical precursors for sol–gel synthesis because they react readily with water. The reaction is called hydrolysis, because a hydroxyl ion becomes attached to the silicon,CHAPTER- I INTRODUCTION TO NANOMATERIALS 1.1,Ex: Lithography, Ball milling, Epitaxy, etc. e) Porosity – It is the ratio of pore volume to its total volume. Here, pore volume is the difference between the total volume and solid volume. f) Pore diameter - The average or effective diameter of the openings in a membrane, screen, or other porous material is known as pore diameter.Journal of Nanoscience and Nanotechnology,Ball Milling of Copper Powder Under Dry and Surfactant-Assisted Conditions—On the Way Towards Cu/Cu 2 O Nanocatalyst Katalin Musza, Márton Szabados, Adél Anna Ádám, Zoltán Kónya, Ákos Kukovecz, Pál Sipos, and István Pálinkó J.
