The general chemical formula of M-type hexaferrite can be written as MFe12O19 (M = divalent elements like Ba, Sr, Pb, Zn, Mg, Ni etc.) which is like the magnetoplumbite structure2. Due to prominent electrical, magnetic, optical, and electromagnetic properties, M-type hexaferrites ...
Detailed Studies of a High-Capacity Electrode Material for Rechargeable Batteries, Li2MnO3−LiCo1/3Ni1/3Mn1/3O2 Lithium-excess manganese layered oxides, which are commonly described by the chemical formula zLi2MnO3−(1 − z)LiMeO2 (Me = Co, Ni, Mn, etc.), are of ... N ...
The hydrothermal reactions of NaZr2(PO4)3 with Na2SiO3 in excess NaOH at 300°C have been investigated. The pure precursor phases have been obtained at the reactant ratio of NaZr2(PO4)3∶Na2SiO3 from 1∶1 to 1∶3.2. When the reactant ratio reached 1∶3.5 in the case of a large...
Classical Scherrer formula Eq. (1) is used to calculate the crystallite size of all samples [46].(1)τ=sλβcosθwhere τ signifies the crystallite size, s = 0.94 as indicates the shape factor, β denotes the full line width at half maximum intensity (FWHM), λ represents the ...
fiber, jute (71%) and hemp (88%) fiber31,84. However, using the well-known scherrer formula, the crystallite size (CS) of the KMnO4treated APFs was found to be 6.75 nm and it was higher than that of untreated (1.9 nm) AP fiber. The crystalline size value is lower than that of ...
Methane oxidation over the iron oxides started at as low temperature as [formula], at which the goethite changed to a hematite (α-Fe[sub 2]O[sub 3]). The conversion ratio was low by the acidic goethite, in spite of its low crystallinity and high specific surface area. The basic ...
