High-yield synthesis of silicon carbide nanowires by solar …

We report a reasonably high yield (∼50%) synthesis of silicon carbide (SiC) nanowires from silicon oxides and carbon in vacuum, by novel solar and lamp photothermal ablation methods that obviate the need for alysis, and allow relatively short reaction times (∼10 min) in a nominally one-step process that does not involve toxic reagents. The one-dimensional core/shell β-SiC/SiOx

(Silicon carbide crystals.Shutterstock) Silicon atoms outnuer carbon atoms in the Earth''s crust more than 1,000-fold, yet the two elements are remarkably alike, chemically speaking. In fact, they''re stacked right atop one another on the Periodic Table. Yet life as

Cast iron - Wikipedia

Cast iron is a group of iron-carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the

Fly ash - Wikipedia

Fly ash material solidifies while suspended in the exhaust gases and is collected by electrostatic precipitators or filter bags. Since the particles solidify rapidly while suspended in the exhaust gases, fly ash particles are generally spherical in shape and range in size from 0.5 µm to 300 µm. The major consequence of the rapid cooling is

working of ball mill pdf

The working principle of ball mill - Meetyou Carbide The ball mill consists of a metal cylinder and a ball. The working principle is that when the cylinder is rotated, the grinding body (ball) and the object to be polished (material) installed in the cylinder are rotated by the cylinder under the action of friction and centrifugal force.

Microstructure and mechanical properties of liquid phase …

Silicon carbide (SiC) composites were prepared by hot-press sintering from α-SiC starting powders with BaAl 2 Si 2 O 8 (BAS). The effects of additives on densifiion, microstructure, flexural strength, and fracture behavior of the liquid phase sintered (LPS) SiC composites were investigated.

Boron-doped hydrogenated amorphous silicon carbide (a-SiC:H) thin films are deposited using high frequency 27.12 MHz plasma enhanced chemical vapor deposition system as a window layer of silicon heterojunction (SHJ) solar cells. The CH 4 gas flow rate is varied to deposit various a-SiC:H films, and the optical and electrical properties are investigated.

Siloxane - Wikipedia

A siloxane is a functional group in organosilicon chemistry with the Si−O−Si linkage. The parent siloxanes include the oligomeric and polymeric hydrides with the formulae H(OSiH2)nOH and (OSiH2)n.[1] Siloxanes also include branched compounds, the defining feature of which is that each pair of silicon centres is separated by one oxygen atom
