MgO nanoparticles with an average size of 30 nm were prepared by a traditional sol–gel method using magnesium chloride and NaOH aqueous solution as the raw materials. X-ray diffraction (XRD) and transmission electron microscopy (TEM) were used to characterize the products. The catalytic effect of the MgO prepared on the decomposition of ammonium perchlorate (AP) was investigated by differential thermal...
CaO-doped zirconia was synthesized by a traditional sol–gel method using both NaOH and ammonia solutions as precipitants. The high-temperature phase stability was investigated following calcining at 1000 °C for 2 h. XRD and Raman spectra were used to characterize the crystal form of the zirconia. The results indicate that the concentration of OH − introduced into the ZrO 2 lattice...
