Then, the refractory combination powders had been placed inside a steel mildew and combined with an organic binder (ethylene glycol at 2 wt. %) to be uniaxially pressed (UP) at one hundred MPa for two min, so four batches of samples have been compacted.
If the brick is of the density required by the operator, the operator will assume that the strain generated by the toggle press or friction press is passable. Due to this fact, based on the earlier bodily and microstructural results, in magnesia samples (i.e., 100 wt. % MgO), a microstructure with small grains was observed, as a result of the temperature used to sinter this green compacts was not high enough to activate both the thermal technique of mass switch and the stable diffusion of the particles to acquire a rough grained material or a densified material, for the reason that theoretical sintering temperature of MgO (1800 °C) is higher than that used.
