Experimental Preparation of Magnesium Oxide Board

Abstract:

In the present, global production of magnesium oxide (MgO) boards comes exclusively from China. However, Slovakia is one of the leading countries in the mining of magnesite. Therefore, an experiment of MgO board preparation from local resources was realized. The experimental board was made from the calcined magnesite mined out in Hačava in Eastern Slovakia. The paper describes the production process of the MgO board in laboratory conditions. In order to compare the experimental MgO board with a MgO board from China, the tensile strength in bending was examined. The experiment demonstrates that the tensile strength of the experimental MgO board in bending in one direction is higher than the declared strength of the commercial board, but in the second direction it is nearly a half of the declared strength of the commercial MgO board. The results of this paper confirm the potential of the MgO board production from local resources.
