HIGH-TEMPERATURE MEASUREMENTS OF THE RATE OF UPTAKE OF RUBIDIUM CHLORIDE VAPOR BY SELECTED OXIDES
Abstract
In a program for the elucidation of the process of formation of radioactive fallout, the rates at which substrate samples of a clay loam and a calcium ferrite took up vaporized rubidium chloride were measured. The rate measurements were made in air from 1100 to 1450C and over a rubidium chloride partial pressure range of about 1 x 10 to the 6th to 5 x 10 to the -4th atm. The clay loam took up rubidium chloride vapor at a rate determined by the rate of diffusion of the rubidium chloride vapor through the surrounding air. The calcium ferrite took up the rubidium chloride at a slower rate which was governed by the rate of reaction of the rubidium chloride with the calcium ferrite at the substrate surface. The uptake of rubidium chloride vapor by a series of simple, unmelted oxides at 1400C was also measured. In general, the rubidium chloride reacted most with acidic oxides such as Nb2O5 and TiO2 and least with basic oxides such as SrO and MgO.
