Gamma-Densitometer for Studies of High-Temperature Metal Melts
2018
The set-up for the measurement of the density of high-temperature melts by means of penetrating gamma-radiation is described. The modern device base, which makes it possible to automatize the work, is the main difference from the earlier existing gamma-densitometers. The key characteristics of the absolute measurements with the use of very exact values of the mass attenuation coefficient for the gamma-quanta beam are described and the accuracy of measurements is estimated. The results of the density measurement of the molten aluminum, cadmium, tin, and bismuth are presented; they confirm the a priori estimate of the error.
