• Inhalation Risk: A nuisance-causing concentration of airborne particles can be reached quickly when dispersed.
• Effects of Short Term Exposure: May cause mechanical irritation.
• Effects of Long Term Exposure: Lungs may be affected by repeated or prolongated exposure to dust particles.
• Properties and Applications: Magnesium oxide (MgO) is valued for its eco-friendly, economically feasible, and industrially important nanoparticles with various physicochemical behaviors. These include outstanding refractive index, corrosion resistance, thermal conductivity, physical strength, stability, flame resistance, dielectric resistance, mechanical strength, and optical transparency. It finds applications as semi-conducting materials, catalysts in organic transformations, sorbents for organic and inorganic contaminants from wastewater, electrochemical biosensors, photocatalysts, and refractory materials. Additionally, it possesses antibacterial, anticancer, and antioxidant properties.
• Surface Modification: Despite its excellent properties, the large crystalline size and low surface area of magnesium oxide nanoparticles limit their practical utility. Researchers are addressing this limitation by modifying surface area with particle size through morphological studies.
• Pollutant Removal: MgO is widely used for pollutant removal due to its fascinating properties. Its morphology and pore structure directly affect the removal capacity of anionic contaminants. Factors such as cation exchangeability and surface functional groups play a key role in removing heavy metals and dyes using MgO.
• Adsorbent of Choice: MgO has become a preferred adsorbent among metal oxides due to its cost-effectiveness, abundance, availability, and excellent adsorption properties. It is utilized in environmental applications owing to its non-toxicity, basic nature, and various surface vacancies, with nanomaterials proving particularly effective.
• Industrial Uses: MgO finds indispensable applications in agriculture, industry, medicine, chemistry, and refractories. In construction, reactive MgO serves as an expansive agent and binder. Its production mainly relies on the dry route, involving the processing of mineral resources like magnesite (MgCO3). However, challenges exist in achieving carbon neutrality due to CO2 emissions during calcination. The vast magnesium reserves in oceans and lakes offer potential solutions, with seawater alone capable of supplying MgO feedstocks for a significant duration.

Conversion of magnesium fluoride to magnesium hydroxide

10.1016/S0892-6875(03)00002-5

The research investigates the conversion of magnesium fluoride to magnesium hydroxide as part of a process to remove magnesium from zinc sulphate electrolyte in electrolytic zinc plants. The study aims to improve the conversion process to reduce the residual fluoride content in the magnesium hydroxide product, which is essential for its marketability. Experiments showed that optimizing operating conditions such as reaction temperature, stirring velocity, and leach concentration could not reduce the residual fluoride content to below 1 wt%. X-ray diffraction analysis indicated that the residual fluoride was incorporated into the brucite crystal structure. However, it was possible to reduce the fluoride content by calcining the magnesium hydroxide to magnesium oxide at temperatures above 1273 K, resulting in a saleable product with less than 1 wt% fluoride. The study concludes that while complete conversion to pure magnesium hydroxide is not feasible, thermal decomposition to magnesium oxide is a viable alternative for producing a marketable product.

Efficient synthesis of-Hydroxy sulfides and-Hydroxy sulfoxides catalyzed by Cu/MgO under solvent-free conditions

10.1080/00397910903219500

The research focuses on the efficient synthesis of β-hydroxy sulfides and β-hydroxy sulfoxides, which are important intermediates in the synthesis of pharmaceuticals and natural products. The study presents a method that utilizes Cu/MgO as a heterogeneous catalyst to achieve regio-, stereo-, and chemoselective ring opening of epoxides with thiols under solvent-free conditions at room temperature. The process yields the corresponding β-hydroxy sulfides and β-hydroxy sulfoxides in excellent yields within a short period.
