METAL-WATER REACTIONS: IX. THE KINETICS OF METAL-WATER REACTIONS- FEASIBILITY STUDY OF SOME NEW TECHNIQUES
A feasibility study was carried out which demonstrated the ability of the Thermodot, a commercial radiometer, to follow temperature transients occurring as the result of the zirconium-steam reaction. The instrument was employed to measure surface temperature at 1600 to 2300 tained C; the instrument is capable of covering a much wider range of temperature. In the study of the Thermodot, electromagnetic levitation melting of zirconium was developed. Zirconium was melted while suspended in a radiofrequency field. The design of coils required to obtain symmetric and relatively quiescent melts is discussed. Emissivities of oxidized and non-oxidized zirconium surfaces were measured at 0.65 ation , with an optical pyrometer and at 2.3 ation with the Thermodot modified with a special filter. The considerations important in the interpretation of temperature measurements in regard to reaction rates are discussed. Suggestions for additional studies are made. (auth)
