Figure 1: Experimental schemes of slow addition (on the left) and of parallel addition by a mixing system (on the right).
Figure  2: Diffractogram of a product (addition mode: parallel with mixing system, C MgCl2 , 6H2O =0.81 mol/L) get by X-Ray diffraction at 0.154 nm (Cu) (measurement   step=0.0334   °2theta;   duration measurement=50 secondes).
Figure 4 shows that both products have micro-pores: gas is absorbed at very low relative pressures
Figure 6 (on the right): Sampling time influence on particle size distribution (addition mode: parallel addition with mixing system, C MgCl2 , 6H2O =0.81 mol/L)
