Determination of specific surface area of thorium dioxide powder by multipoint BET method
Description
Thorium dioxide powder has seen important as a new nuclear fuel, which has better thermal conductance than uranium dioxide powder. Nitrogen adsorption is an effective method in the study of specific surface area of ThO2. Basing on the BET theory and studying the behavior of ThO2 powder absorbing N2 at liquid nitrogen temperature. It has been taking many studies on the sample volume, the time of desorption and the temperature of desorption to study the factors that influence the specific surface area of ThO2. Through orthogonal experiments, the best determination parameters were found and the determination method of specific surface area of thorium dioxide powder was established. The precision of this test method can be better than 2%. (authors)
