  The viability of ultrasonic sonochemistry is investigated in the context of
delivering air-stable metallic Al rich-PVP composite. The parameters
investigated are; sono-(1) process intensification, (2) crystallization, (3)
agglomeration, and (4) fragmentation, respectively. The conventional solvent of
n-hexadecane is employed as the sonotrode generated pressure transmitting
medium to carry out the above experiments. Two precursors, (1) Poly
(vinylpyrrolidone) (PVP) and (2) Aluminum chloride (AlCl3) are chosen to
evaluate and demonstrate the viability of the ultrasonic induced processing.
Temperature controlled investigations at RT and higher temperature help in
achieving; (a) PVP-graphitization, and (b) Al-crystal growth phenomenon,
respectively. The current experiments aid in helping to isolate and identify
actual mechanistic happenings. The investigation, thus, has a fabrication
protocol of shortened processing-duration, native amorphous oxide-free,
metal-rich air-stable product that leads to 10 g of composite product for fuel
applications.
