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.  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.

Jan 02, 2021 More than 85% of this historic town is a National Historic District, and it is renowned for its architecture and its long mining history.Before Europeans settled here in 1821, Native Americans mined the area for over a thousand years, and they brought the mineral galena, a lead oxide, out of the earth.
Jul 06, 2013 Concern about security of supply of critical elements used in new technologies, such as the Rare Earth Elements (REE), means that it is increasingly important to understand the processes by which they are enriched in crustal settings.High REE contents are found in syenite-dominated alkaline complexes intruded along the Moine Thrust Zone, a major collisional zone in north-west Scotland.
Lead Powder Mill Lead Acid Battery Manufacturing.In the ball mill, lead is converted to lead oxide, by grinding and oxidation process, which is an exothermic process in this process, heat is generated and temperature of oxide is increased, to control the temperature with in the operating range of to c, the ball mill temperature is controlled .
Mar 18, 2015 This study presents the use of TiO 2 nanoparticles with Tm as photoelectrodes in DSSCs.The nanoparticles were annealed at 1173 K and the predominant TiO 2 phase was rutile.XRD and Raman spectroscopy revealed the presence of a crystalline pyrochlore phase of the mixed oxide Tm 2 Ti 2 O 7.
Mar 18, 2020 Agro-industrial biomass residues (peanut shells, cocoa husks, sugarcane bagasse and coconut mesocarp) were converted into magnetic adsorbents by deposition of maghemite (γ-Fe2O3), employing the combustion synthesis method as a single step route.The resultant magnetic materials were characterized by XRD, TEM, nitrogen adsorption, and magnetization measurements.
Milled in a centrifugal ball mill, Retsch S100, with 20-mm-diameter agate balls for 100 h.This treatment leads to a smaller and more homogeneous particle size.The size after 30-h milling was about 130 nm and slightly smaller after 60- and 100-h milling.
