Silicon carbide (SiC) has high thermo-mechanical properties and high resistance for high temperatures. Therefore, it may be recognized for the improvement of the efficiency of electric energy production. SiC nanoparticles shows high surface area hence it may be applicable in power plants. High temperatures are needed for its synthesis. In the present work, SiC nanopowder is synthesize via sol-gel method. The mixture of SiO2:Mg in the molar ratio 1:2 heated in the furnace at 650°C for 6 hours. For an acid etching of the obtained product for 5 hour a mixture of HF 10% wt and HNO3 4 M were used. Then the mixture is washed with distilled water and dried at room temperature. The final product is SiC.The synthesized nanoparticles are characterized by X-Ray powder Diffractometer (XRD), Fourier Transform Infra Red Spectroscopy (FTIR). The ultrasonic velocity, density and adiabatic compressibility were analyzed and the results were discussed. Average particle size has been estimated by using Debye-Scherrer formula. It was found to be 30 nm. Thermo acoustic properties of nanomaterials related to the surface of nanoparticles and nanoparticle surfactant interactions. Material characterization of SiC nanofluid was studied by non-destructive technique at various molar concentrations, temperatures and frequencies. The molecular properties of ultrasonic waves in nanofluids undergo changes in highly associated systems and dependent on the cohesive properties of liquids. In the present investigation an attempt is made to study the thermoacoustic behavior of prepared nanofluids in methanol at various concentrations.
