Magnesium oxide is considered an electrical insulating material that has a good heat transfer ability.[4]
Magnesium oxide as a refractory material, that is, a material that is It is stable physically and chemically at high temperatures. It has two useful features of high thermal conductivity and low electrical conductivity. By far the largest consumer of magnesium worldwide is the refractory industry, in the United States in 2004 about 56% of magnesium oxide was consumed in the refractory industry, with the remaining 44% in agricultural, chemical, construction, environmental, and other industrial applications. has been used MgO is used as a refractory raw material for the construction of furnaces and crucibles. Magnesium oxide is the main material for the production of fireproof materials in the construction materials industry. In the construction industry, magnesium oxide precast walls have several attractive properties: fire resistance, termite resistance, moisture resistance, rot and mold resistance, as well as good mechanical resistance. MgO is one It is one of the components of Portland cement in the drying process
Since magnesium oxide is a good acid buffer and also has a good effectiveness in stabilizing heavy metals soluble in water, it is widely used in soil amendment and It is used in groundwater treatment, wastewater treatment, drinking water treatment, air treatment and industrial water treatment. Many heavy metals such as lead and cadmium are present in acidic pH (below 6) and high pH (above They have more solubility in water than 11). The solubility of heavy metals affects the stimulation and type of life of biomass and their mobility in soil and underground water. Most metal species are toxic to humans in certain concentrations, so it is necessary to minimize their entry into water in the form of directly accessible biomass and mobility. Magnesium oxide in granular form is often mixed with soil and metal minerals. Others are mixed, usually with a low (acidic) pH to move the pH into the 8-10 range where most metals are at their lowest solubility. Metal hydroxide complexes tend to precipitate from aqueous solution in the range of pH 8-10. MgO is widely considered as the most effective stabilizing compound of metals in Portland cement, lime, foundry powders, power generation supplies and various specialized products due to its buffering properties, cheap price, and ease of transportation.
\r \nAnd very importantly, the products marketed for metal stabilization technologies do not create the appropriate pH conditions in groundwater aquifers, whereas MgO creates an ideal pH of 8-10. In addition, magnesium is an essential element for most biological systems in groundwater and soil, which restores and improves the population of microorganisms.
