The kinetics of volatilization of phosphorous oxide from phosphosilicate glassceramic powders prepared by a sol-gel process were investigated at a given temperature. The rate of P2O5 vaporization increased with the P2O5 concentration in the phosphosilicate powder. Vaporization from the powder containing 46% P2O5 was analyzed using a kinetic model for diffusion limited evaporation. The diffusion through phosphosilicate glass in the surface of each particle in the temperature range 800~85$0^{\circ}C$ are presented.
