Methods： Nano-sized Cu1.5Mn1. 5O4 was synthesized by solid-state chemical reaction method and the influences of particle size and the optimum conditions were investigated by single factor and uniform design. The composite oxide particle size and characteristic of the product were obtained by XRD. Result： The optimum conditions for the product with the smallest particle size were： microwave heating time = 15 min, microwave power=540 W, thermal decomposition time = 2.0 h and thermal decomposition temperature = 370 ℃ by single factor and homogeneous design. The main phase of the product was Cu1. 5 Mn1. 5 04, which belonged to isometric system and the space group was Fd3m. Conclusions： Solid-state chemical reaction method is productive, environmental friendly and energy efficiency.
