DEAGGLOMERATION OF KAOLIN BY HIGH-ENERGY, IONIZING RADIATION. Annual Technical Status Report No. 1 Covering the Period 1 April 1959 to 31 March 1960
The objective of this research program is to investigate the possibilities of using high-energy ionizing radiation to reduce agglomerates of kaolin plates to discrete particles. Samples of a well-crystallized kaolin from Washington County, Georgia, were subjected to both x and gamma radiation. The results of physical tests made on the samples irradiated with the gamma research irradiator and a sample given a total energy dose of 1 x l0/sup 21/ ev per gram with a 150-kv x ray machine indicate that kaolin stacks can be deagglomerated with high-energy ionizing radiation. The data from x-ray- diffraction studies show a definite decrease in the degree of crystallinity for kaolin subjected to high-energy ionizing radiation. Research in the immediate future will be concerned with further evaluation of the samples irradiated to date, particularly with respect to particle size, reflectance, and electron- diffraction studies. In view of some of the results contained in this report, grinding studies cf kaolin before and after irradiation have become of prime importance. These studies will begin early in the next year. Future experiments will be designed to obtain more information as to the processes that take place when kaolin is subjected to high-energy ionizing radiation. (auth)
