摘要： In one aspect, the present invention relates to a method of making multi-phase particles that include nanoparticulates and matrix, which maintains the nanoparticulates in a dispersed state. A flowing gas dispersion is generated that includes droplets of a precursor medium dispersed in a gas phase. The precursor medium contains liquid vehicle and at least a first precursor to a first material and a second precursor to a second material. The multi-phase particles are formed from the gas dispersion by removing at least a portion of the liquid vehicle from the droplets of precursor medium. The nanoparticulates in the multi-phase particles include the first material and the matrix in the multi-phase particles includes the second material.
