1.	After drying process the liquid phase is removed from the gel and ___________ is performed.(a) Calcination(b) De-oxygenation(c) Oxygenation(d) HydrogenationI got this question in an internship interview.I'd like to ask this question from Sol-Gel Method and Chemical Reduction Method topic in chapter Nano Materials of Applied Chemistry
Answer» Right ANSWER is (a) Calcination The best I can explain: After drying process the liquid phase is removed from the GEL and calcination is PERFORMED in order to enhance the MECHANICAL properties. Alcohol is used as a solvent.
