“…The micrographs reveal that strontium hexaferrite annealed at 1,000°C as in Figure 3 shows the presence of hexaferrite indicating a proper c-axis orientation of nanoparticle. Nanoparticles annealed at 1,000°C possess a uniform hexagonal shape with narrower particle size distribution hence narrow size distribution leads to lower porosity [55]. When particles are annealed at 1,300°C the nanoparticles illustrate an increase in the average grain sizes with calcination temperature due to the fusion of smaller grains into larger grains [56][57][58].…”

In this study, strontium hexaferrite nanoparticles synthesized by sol–gel autocombustion method and the effect of high annealing temperature on produced nanoparticle have been studied. Powders were annealed at 1,000 and 1,300°C. Structural properties of synthesized powders were analyzed by X-ray diffraction (XRD). Hexagonal structure and shape of SrFe12O19 nanoparticles were analyzed from field-emission scanning electron microscope and transmission electron microscope figures. Fourier-transform infrared spectroscopy confirmed the formation of an M-type hexagonal structure. The thermal behavior of nanoparticles has been investigated by thermogravimetric analysis (TGA and DTG). Height measurement of nanoparticles with 2D and 3D images of the surface obtained from atomic force microscopy. XRD pattern of strontium hexaferrite nanoparticle was used for determining the crystal structure and examining the effect of high annealing temperature on powders by finding lattice parameters, densities, crystallite size, specific surface area, and strain. Crystallite size, strain, and bulk density decreased when produced nanoparticles annealed at 1,000°C with decreased porosity when nanoparticles were annealed at 1,300°C. The specific surface area was found to be increased when nanoparticles were annealed at 1,000°C. In this study, influence of high temperature on the structure of SrFe12O19 nanoparticles was studied.

“…Majouli et al [ 14 ] fabricated tubular microfiltration membranes from Moroccan perlite for water purification. Other researchers have employed low-cost materials such as fly ash [ 15 ] and industrial waste [ 16 ] as fillers for the fabrication of ceramic membranes. Ben Amar and Oun [ 17 ] used Tunisian mud as a low-cost material for the fabrication of tubular ceramic ultrafiltration membranes for removing pollutants from wastewater.…”

In this study, a method for fabricating tubular ceramic membranes via extrusion using economical and locally available bentonite–silica sand and waste palm leaves was developed as a tool for conducting the necessary task of purifying water polluted with oil and suspended solid materials produced via various industrial processes. The developed tubular ceramic membranes were found to be highly efficient at separating the pollutants from water. The properties of the fabricated membrane were evaluated via mechanical testing, pore size distribution analysis, and contact angle measurements. The water contact angle of the fabricated membrane was determined to be 55.5°, which indicates that the membrane surface is hydrophilic, and the average pore size was found to be 66 nm. The membrane was found to demonstrate excellent corrosion resistance under acidic as well as basic conditions, with weight losses of less than 1% in each case. The membrane surface was found to be negatively charged and it could strongly repulse the negatively charged fine bentonite particles and oil droplets suspended in the water, thereby enabling facile purification through backwashing. The obtained ceramic membranes with desirable hydrophilic properties can thus serve as good candidates for use in ultrafiltration processes.
