Decomposition of mgco3
WebAug 14, 2014 · Magnesium carbonate MgCO3 (magnesite) was experimentally studied at pressures of 12–84 GPa and temperatures between 1,600 and 3,300 K. We applied the high-pressure technique using a multianvil press and a diamond anvil cell with laser heating. The phase relations and melting of magnesite were investigated by means of Raman … WebJun 1, 1989 · In the present study it is demonstrated that calcination of MgCO3 to produce MgO in the presence of biomass and waste plastics has resulted in up to 99% carbon di oxide and methane reduction.
