In this study, diasporic bauxite was mechanically activated for different durations (15, 30, 60, 90 and 120 min) by the planetary mono mill. The speed of the main disk and ball-to-mass ratio were kept constant at 600 rev ...

The kinetics of grain growth in 1-4 wt. % TiO2-doped ZnO was studied using the simplified phenomenological grain growth kinetics equation together with examination of microstructure and densification of the sintered samples. ...

Nickel is essential metal due to usage area as stainless steel, non-ferrous alloy production, electroplating and chemical industry. Degradation of nickel sulphides leads to extraction of nickel from laterites. High cost ...

The study was designed to test the efficiency of of Silybum marianum in different doses to treat carbon tetrachloride (CCl4) induced liver damage. Thirty-five Wistar albino rats were divided randomly into five groups as ...

The decomposition and acid leaching has been investigated of alunite ore activated mechanically by grinding in a planetary ball mill in air atmosphere for 0, 15, 45 and 90 min. The mechanical activation appears to decrease ...

The effects of mechanical activation on the soda roasting of chromite were investigated in this study. Structural changes in mechanically activated chromite were examined using X-ray diffraction analysis (XRD), surface ...

In this study, mechanical activation process was used for intimate mixing as well as producing finely ground particles, increased surface area and improved chemical reactivity of milled materials for producing SrTiO3 from ...

The alkali-fusion method was carried out by reacting chromite concentrate with molten sodium hydroxide under oxidizing conditions to form sodium chromate. The fusion product was leached with methanol to remove the unreacted ...

In this study, fine grained SiO2 was exposed to CRN, and then Si3N4 ceramic powders were produced. Initially, 5wt% Li2O-5 wt% Y2O3 (based on the final product) and carbon black were added to SiO2, and then powder samples ...
