Gunpowder, also known since the late 19th century as black powder, was the first chemical explosive and the only one known until the mid-1800s.It is a mixture of sulfur, charcoal, and potassium nitrate (saltpeter)—with the sulfur and charcoal acting as fuels, while the saltpetre works as an oxidizer.[2] [3] Because of its burning properties and the amount of heat and gas volume that it .

Hydrated aluminum oxide (Al 2 O 3.3H 2 O) and a mixture of phosphorus pentoxide (P 2 O 5) and hydrated aluminum oxide were used by Zhang et al.(2004) to modify talc particles and study its effects on filler retention in the papermaking system.The talc modification had great impact on filler retention.

In order to modify the shape of the obtained silicon-based particles, a dry-milling step is performed.The powder obtained after plasma synthesis is thus milled in a Simoloyer high-energy ball-mill using a rotation speed of 800 rpm, a ball-to-powder mass ratio (BPR) of 20:1 and a milling time of 495 minutes.

In this study, high-energy ball milling was applied to synthesis in situ nanostructured copper based composite reinforced with metal carbides.Cu, M (M=W or Ti) and graphite powder mixture were mechanically alloyed for various milling time in a planetary ball mill with composition of Cu-20vol%WC and Cu-20vol%TiC.
