Abstract:

Using the gravimetrical method, the kinetics of the interaction of high-alumina concrete with the melt of fluoride KF-AlF(3) in the temperature range from 700 to 800 degrees C is considered. Such analysis allows one to observe the variation in the weight of the examined material placed into the molten salt mixture during the experiment and to calculate the rate of the weight increment. As a result of the investigations, the way the concrete binding material interacts with the melt is revealed. The character and kinetics of this interaction are affected by the concentration of dissolved Al(2)O(3), melt temperature, and preliminary thermal treatment of the concrete. After the experiments with the melt saturated by alumina (5 wt \% Al(2)O(3), T = 700 degrees C), the samples totally kept their form and sizes. When the alumina content in the melt is lower than 2.5 wt \%, the samples are subjected to corrosion. It is shown that it is possible to use high-alumina concrete as a construction material for electrolysis baths in the future, if potassium cryolite is used.
