Magnesium borates are excellent materials due to their thermal and mechanical properties. In this study, the thermal (solid-state) synthesis was used for the production of ton-hydrated magnesium borate minerals. In the X-ray diffraction results of thermal Synthesis, Kotoite (K) "01-075-1807, Mg-3(BO3)(2)"; Suanite (S) "01=086-0531, Mg-2(B2O5)" and (MgB1) "00-031-0787, VIg1,3407" and (MgB') "01-073-2232, Mg2B2O5" were produced. Higher XRD scores were seen at the molar ratios of 3:2 and 1:1. Materials, XRD scores increased With increasing temperature and time. Molar ratios, reaction temperature and time for the best crystal magnesium borate materials production were determined as 3:2-1:1, 1000 degrees C and 240 min. Products at the highest XRD scores were subjected to neutron permeability analyses. Menton permeability decreased With increasing thiclaie& of the,material:jncrease of molar ratio of the raw materials cohtributect to the neutron permeability of product. The lowest values of total macroscopic cross section and neutron permeability have been found for 3:2 of MgO:H3O3 ratio and 1.25 cm thickness.
