Abstract

Yttrium silicate is one of the promising environmental barrier coating materials used to protect ceramic matrix composites (CMCs) under specific operating conditions. In this paper, yttrium monosilicate (Y2SiO5, YMS) nanoparticles were synthesized using a molten salt method with a low synthesis temperature. To find the optimal experimental parameters, YMS nanoparticles were synthesized under different conditions using the molten salt method. The experimental parameters, such as different precursor/salt ratios, precipitants, calcination temperatures, and holding times, were studied. The samples were systematically characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), and BET method. The results showed that all the parameters we mentioned have effects on the synthesis of Y2SiO5 nanoparticles, especially the calcination temperature, the precipitant, and holding time.
