Cerium hydrothermal
WebMicrowave-assisted hydrothermal synthesis followed by high-temperature (1050 degrees C) calcination was used to prepare pure and cerium-doped zinc orthosilicate (Zn2SiO4) pigments. Nanoscale Zn2SiO4 and Ce-Zn2SiO4 powders were blended with potassium silicate (K2SiO3) and then applied to the aluminum substrate to obtain thermoregulating … Webof the nanostructure with respect to their bulk like materials. The solvent composition and the cerium source are of importance in the final product morphology (Chowdhury, 2011; Lin, 2010). The reaction temperature, concentration of the cerium source, and reaction time has a significant influence on the yield of CeO 2 nanorod
