摘要	We herein report a novel carbon-coated coprecipitation method to synthesize non-agglomerating submicron/nano-beta-Yb2Si2O7 powders. Yb(C2H3O2)(3)center dot 4H(2)O and silica sol (alkaline) were chosen as the ytterbium source and silicon source, respectively. A carbon surface layer is processed using sucrose as carbon source to hinder the contact and sintering of beta-Yb2Si2O7 particles during heat treatment under a protective atmosphere, and then the carbon layer could be completely removed by inletting air at 900 degrees C during cooling process. The as-synthesized Yb2Si2O7 powders demonstrate an average size of 271 nm with a narrow distribution of 142-531 nm. The results show that the carbon layer could successfully solve the severe agglomeration or sintering of nanometer beta-Yb2Si2O7 particles during the calcination process. The as-developed carbon-coated coprecipitation technique is an effective method to fabricate high purity submicron/nano-Yb2Si2O7 powders.
