%X Rates of volatilization of SnO from the binary silicate melts containing 60.60 to 91.00 wt.-% SnO were measured by the "Loss Weight" method. It was found that the logarithm of volatilization rate or vapour pressure of SnO is proportional to the composition of the melt. From these experimental results the activities of SnO and SiO_2 were calculated, and it occurred that they exhibit considerable negative deviation from Raoult's Law. Since the rate of volatilization varies exponentially with the SnO content in the binary melt, it is unlikely that this deviation is associated with the formation of compound between. SnO and SiO_2.
