Abstract


Turkey has the largest borax, ulexite and colemanite reserves in the world. All the countries are dependent upon colemanite and ulexite reserves of Turkey. In this study depending on the ability of neutron absorption of secondary ulexite mineral, the structural and physical properties are examined. Firstly, the sieve analysis of secondary ulexite mineral is made then four different particle sizes of secondary ulexite minerals are selected, prepared and X-Ray Diffraction of secondary ulexite minerals is made for structural analysis. After that, B2O3 contents of secondary ulexite minerals are analyzed experimentally. After these examinations X-Ray Florescence analysis is made for the determination of Zn, and Fe and Ar contents.  Thermal analysis of secondary ulexite minerals is performed for obtaining the energy and weight changes with temperature. For this aim, the method of Differential Thermal Analysis and Thermal Gravimetry is used. Afterwards, secondary ulexite mineral is tested in the Howitzer equipment for the nuclear absorption and confront with the colemanite mineral that is mostly used in the experiments at this field of study
