To investigate the effect of different passivators on the fixation of phosphorus in soil, MgO, ammonium alum and their mixtures were added to the soil in different proportions in an indoor incubation test to study their effects on the phosphorus content and phosphorus fraction of 0.01 mol-LCaCl leaching and 0.5 mol-LNaHCO leaching. The results showed
Both spherical alumina and spherical magnesium oxide are developed continuously with the technological development of electronic industry. At present, spherical alumina is still the main force of commercial thermal conductive filler, but the thermal conductivity of spherical magnesium oxide can reach as much as 1.5 times that of spherical alumina, which greatly enhances the flexibility

Spherical magnesium oxide was prepared by aerosol-assisted method using magnesium chloride as the magnesium source and urea as the precipitant. The precursors and magnesium oxide samples prepared at different reaction temperatures were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), infrared spectroscopy (IR) and nitrogen adsorption-desorption. The experimental results showed that the specific surface
Active magnesium oxide is also called lightly burned magnesium oxide or caustic magnesium oxygen, is calcined below 900 ℃ magnesium compounds formed magnesium oxide, the chemical activity of magnesium oxide can be expressed by the iodine absorption value (adsorption performance index), the greater the chemical activity, the greater the iodine absorption value, the more lightweight.

Polyethylene (PE) is a thermoplastic resin obtained by polymerization of monomer ethylene, with good cold resistance, good mechanical strength, dielectric properties, widely used in cables, films, pipes, packaging, containers, medical appliances and other products. However, PE has an oxygen index of 17.4%, which is a flammable material. PE materials burn quickly, generate heat/smoke, and melt

The change of refractive index of magnesium oxide with uniaxial and biaxial pressurization was calculated by using the first nature principle, and it was found that the dielectric constant decreased by pressurization, and the biaxial pressurization changed magnesium oxide from negative uniaxial crystal to positive uniaxial crystal. Magnesium oxide has many excellent properties, such as

The article reports a facile method to prepare a novel 3D flexible multifunctional nitrogen-doped carbon nanotube electrode. The carbon nanotubes were simultaneously modified by MgO nanosheets. The researchers prepared CF@CNTs/MgO complexes by using a facile liquid-phase impregnation/adsorption method in combination with the pyrolysis of commercially available inexpensive melamine foam (MF). This method allows for efficient
