Boehmite (AlOOH) is useful in several commercial applications. In the present work, AlOOH nano powder was synthesize via sol-gel method. The processes have been conducted from aqueous suspensions at 160 C for 72 h to 168 h with initial acidic or alkaline pH, without or with acetate ion. Scanning Electron Microscopy (SEM) was made by field emission JSM-7401F. Morphology, size, high resolution was viewed with Transmission Electron Microscopy (TEM) using a field emission JEOL JEM 2010F, X-Ray Diffraction (DRX) was obtained with a diffractometer Panalytical, Model: Xpert PRO, equipped with Cu Kα1 radiation and Fourier Transform Infrared (FTIR) was made by spectrophotometer Nicolet; Thermal Analysis TGA/DSC SDT Q600 in air atmosphere with a 10°C/min temperature rate. Ultrasonic studies of Silicon Carbide Nanosuspension were carried out by Pulser Receiver Method.
