Summary

Composite powders of MgO. nAl2O3(n = 1,2,3) have been synthesized hydrothermally using commercially available hydroxide reactants. The synthesis was carried out in an aqueous suspension using a pilot plant installation operating at 4 MPa and the corresponding steam temperature of 523 K. Powder characterization has shown that the particle size ranges from 2 to 10 μm. Sintering of preformed green bodies was carried out at 1873 K in inert gas, resulting in a dense material. Structure and microstructure have been studied by XRD and electron microscopy.
