Experimental design methodology is applied to optimise MgO production. This is a two-step process through an intermediate product (Mg(OH)2). A fractional factorial design and a centred composite one are used to establish experimental conditions for Mg(OH)2 obtention. The favourable conditions for the second step to obtain MgO were determined using a fractional factorial design. The decomposition and crystallisation of Mg(OH)2 was analysed by DTA/TGA and XRD. The morphological properties of the MgO were examined by SEM.
