Measure modified SiO2
at different amount from absolute PVB, and blend it under the influence of ultrasonic.
In order to separate calc-alkaline series with low potassium, average potassium and high potassium and shoshonite ones,  diagram is used that is based on K2O quantities in SiO2
LIM resource definitions includes Hi-SiO2
ores (>=50% Fe =50% Fe, <=18% SiO2
BIF 2 domain is parallel to BIF 1 with lower Fe grades and higher SiO2
and Al2O3 contents.
According to Mir-Sa'sa'ani, the use of SiO2
nanoparticles with initial size of 10 nm and the use of argon laser to cure the composite instead of using common systems such as halogen lamps is among the unique characteristics of this system, to the extent that the plan to produce dental nanocomposite based on (Bis-GMA + TEGDMA + SiO2
) cured by argon laser has been granted in Iran Patenting Organization (IRIPO).

The concentrate grades (Fe, V2O5, TiO2, SiO2
, Al2O3, P, LOI, CaO, K2O, MgO, Mn, Na2O and S) were then back calculated from these estimates.
cables have replaced standard engine wire harnesses on MD-11 aircraft, as well as several 747-400 aircraft.
