abstract = {Magnesium carbonate powders are essential in the
manufacture of basic refractories capable of withstanding
extremely high temperatures and for special types of cement
and powders used in the paper, rubber, and pharmaceutical
industries. A novel synthesis route is based on CO2
absorption/sequestration by minerals. This combines the
global challenge of climate change with materials
development. Carbon dioxide has the fourth highest
composition in earth’s atmosphere next to nitrogen, oxygen
and argon and plays a big role in global warming due to the
greenhouse effect. Because of the significant increase of
CO2 emissions, mineral carbonation is a promising process in
which carbon oxide reacts with materials with high metal
oxide composition to form chemically stable and insoluble
metal carbonate. The formed carbonate has long-term
stability and does not influence the earth’s atmosphere.
Therefore, it is a feasible and safe method to bind carbon
dioxide in carbonate compounds such as magnesite. The
subject of this work is the carbonation of an olivine
(Mg2SiO4) and synthetic magnesia sample (>97 $wt\%$ MgO)
under high pressure and temperature in an autoclave. Early
experiments have studied the influence of some additives
such as sodium bicarbonate, oxalic acid and ascorbic acid,
solid/liquid ratio, and particle size on the carbonation
efficiency. The obtained results for carbonation of olivine
have confirmed the formation of magnesium carbonate in the
presence of additives and complete carbonation of the MgO
sample in the absence of additives},
