Abstract The effects of the ratio of the monomer to crosslinker on the process and property of BeO nanopowders were investigated. The results show that the sulfate salt is disintegrated by the auxiliary three-dimensional (3D) tangled network of polymers, so its thermo-decomposing temperature declines obviously. When the ratio of the monomers and cross linker is 6 : 1, the decline degree of the thermo-decomposing temperature is the highest which is around 177oC; the average particle size of the powders with narrow particles distribution and less aggregation is the smallest which is about 16 nm. When the ratio deviates from 6 : 1, the decline degree of the thermo-decomposing temperature becomes smaller, and the average particle size of the powders increases.
