Silica fume, a byproduct of silicon and ferrosilicon alloy production, is a fine, amorphous powder that possesses pozzolanic properties, meaning it can react with calcium hydroxide in the presence of water to form additional cementitious compounds.
It is obtained as a byproduct in electric arc furnaces used for producing metallic silicon or ferrosilicon alloys.

Remanufacturing aims at the goal to restore the products to the state of a new one in all aspects, and to examine the quality of the remanufactured products according to the criteria of a new one so that the consumers can be supplied with the remanufactured products with high value and the remanufacturing enterprises ears higher benefits.
Fig.2 Classification of key technology for remanufacturing The key technique of remanufacture engineering includes many types, in which the advanced and compound surface techniques play an important role in repairing and strengthening the failure surfaces of waste and old parts.
The Ni-Al alloy coatings was chosed as remanufacting materials.
It can be seen that the surface cylinder ektexine have been repaired and covered with one Ni-Al alloy coatings.
This technology is carried out mainly for axle and hole component, such as recovery the size of crankshaft flange locating surface by using the technology of oxyacetylene flame spraying; anti-hole-corrosion for cylinder jacket by spraying nickel-base alloy; recovery the side surface of main bearing cover in crankcase, camshaft journal and bearing fitting surface of various drive devices by using the technology of electroplating; pile weld the case by applying the argon-arc welding and supplementary process.

Conclusion This work was aimed to studying the adsorption of chromium (VI) on natural and/or modified kaolinite.

Effect of replacing vanadium by nobium and iron on the tribological behavior of HIPed titanium alloys.

By varying the plasma power and pressure, the research aims to elucidate the relationship between the treatment conditions and the resulting film characteristics, particularly the transition from amorphous to crystalline phases.

Such species can oxidize various organic compounds leading to complete mineralization of these compounds.
This work is therefore aimed at comparing on the structural and morphological properties of the anodic oxides formed on these foils in a bath consisting of varying amounts of F-.

Traditionally, when extracting oil, I use special granular proppants: coarse quartz sand, aluminum and its alloys, crushed coke, glass beads, proppants, etc.
There are many studies aimed at obtaining proppants from magnesium-containing materials.
As a result, the phase composition of the fired proppant is represented by magnesium metasilicate in the form of protoenstatite and clinoenstatite, and, to a lesser extent, quartz, cristobalite and a number of ferruginous compounds.
However, in large-scale production, the use of these compounds increases the cost of production.
The chemical compounds that make up the polymer film interact with the gel breakers, gradually decreasing the concentration of breakers in the fracturing fluid.

On the other hand, copper could be detected in many of the industrial wastewater effluents sources including printed circuit board manufacturing, metal finishing industry e.g. pickling of copper and its alloys, electroplating and electro-less plating, electro polishing, paint manufacturing, wood preservatives and printing operations.

Removal of nickel ions by cementation on zinc from NiSO4 solution in presence of accelerator non-toxic organic compounds.

The elastic module of GO (230 GPa) is slightly higher than that of steel and its alloys (190-214 GPa), but comparable to that of Zirconia (160-241 GPa) and Cobalt alloys (200-248 GPa).
Therefore, natural antifouling compounds like papain, butenolide or cardenolides have been studied, however, those still have some technical limitations.
