Obtaining of Iron-containing Silicate Composites for

The maximum sorption of arsenic by the modified sample is 7.8 mg / g, which is significantly higher than that for natural palygorskite 0.2 mg/g. It has been shown that arsenic is removed by iron-containing silicate rather quickly and does not depend on the pH value of the aqueous medium in the range 3–8.

Iron-rich silicates in the Earth's D″ layer

2005-7-12  Although the densities of other lower-mantle silicates, including ferromagnesian silicate perovskite and CaCl 2-type and α-PbO 2-type SiO 2 (8, 21), cluster around 5.6 gm/cm 3 (±2%), the density of the iron-rich ppv silicate increases by as much as 20% depending on the iron content. Such high density in silicate would have a major impact on the seismic and geodynamic properties of the D″

2016-9-11  metal contamination on silicon wafer surfaces becomes more important. Contamination currently accounts for over 50% of the yield losses in semiconductor IC device manufacturing. Surface contamination concentration techniques such as SME-ICP-MS have been used to determine the purity of both the native and thermal oxide layer on silicon wafers.

Silica and its role in the production of iron and steel

SiO2 plays an important role in the production of hot metal (liquid iron) and liquid steel during primary steelmaking. In these slags it is present in the form of silicates and is an important component in determining the basicity (CaO/SiO2) of the slag.
