Magnesium sulfate is a small colorless crystal used as an anticonvulsant, a cathartic, and an electrolyte replenisher in the treatment of pre-eclampsia and eclampsia. It causes direct inhibition of action potentials in myometrial muscle cells. Excitation and contraction are uncoupled, which decreases the frequency and force of contractions.

Dolomite is a common rock-forming mineral. It is a calcium magnesium carbonate with a chemical composition of CaMg (CO 3) 2. It is the primary component of the sedimentary rock known as dolostone and the metamorphic rock known as dolomitic marble. Limestone that contains some dolomite is known as dolomitic limestone.

Using magnesium sulfate from a cost-effective source, dolomite, it was possible to create pure MgTiO 3 devoid of other phases. For making nano-MgTiO 3 in uniform nanostructures and tiny nanosizes, the technique adopted is thought to be excellent. The technique was cost-effective since it only required a temperature of 300 oC.

In general terms, magnesium dissolution is. Dolomite. Dolomite is a double carbonate (Bénézeth et al., 2018) often expressed with the chemical formula CaCO 3 *MgCO 3; it is essentially the interweaving of calcite CaCO 3 and magnesite MgCO 3. It has a crystalline form composed of alternating layers of Mg and Ca separated by layers of …
Dolomite can be used as a raw material (α-magnesium oxide) to produce magnesium oxychloride cement (MOC) (Altiner and Yildirim, 2017a, 2017b). Furthermore, owing to the low magnesium oxide content (about 20%) of dolomite, the carbon dioxide (CO 2) content released from the dolomite used to prepare MOS cement during the calcination …
