Abstract Objectives This study examined the antibacterial and antibiofilm properties of conventional glass-ionomer cement (GIC) modified by the addition of magnesium oxide (MgO) nanoparticles. Materials and methods MgO nanoparticles were characterised by XRD, FTIR, and SEM analysis and tested for its activity against Streptococcus mutans and Streptococcus sobrinus. MgO nanoparticles were incorporated into GIC powder (Ketac Molar Easymix) at different concentrations and the antibacterial […]

The preparation method of micro-nano magnesium oxide with the function of adjuvant and drug carrier involves a preparation method of micro-nano magnesium oxide, weighing MgCO in a beaker, heating with magnetic stirring; adding a mixed solution of oxalic acid/water (v/v=1/5) to the beaker drop by drop, stirring fully while adding drop by drop to make

Magnesium hydroxide and magnesium oxide are widely used in medicine, energy, aerospace, food, daily chemical, catalyst, refractory, flame retardant, heavy metal removal, smoke desulfurization, acid waste liquid neutralization and other fields. Among them, nano-grade magnesium hydroxide, magnesium oxide products have the highest added value. With our country becoming the second largest economy in the world,

In the preparation and production of some advanced ceramics, magnesium oxide is a common additive. What changes it will bring to the ceramics during the sintering process? Let\’s understand it by several cases. Magnesium oxide on alumina ceramics what are the influencing factors? 　　1, magnesium oxide on alumina ceramic sintering temperature and densification of the

The flame retardant mechanism of magnesium hydroxide as flame retardant is: when magnesium hydroxide is decomposed by heat, it releases water and absorbs a large amount of latent heat at the same time, which reduces the actual temperature that the resin bears in the flame and has the cooling effect of inhibiting the decomposition of

As an important chemical material, magnesium hydroxide is widely used in medicine, chemical industry, environmental protection, aerospace and food, etc. It is often used as flame retardant for polymer, neutralizer for acidic waste liquid of environmental protection and raw material for magnesium oxide production. Among many applications, magnesium hydroxide is most often used as a

Magnesium and magnesium alloys are widely studied as the \”green engineering materials of the 21st century\”. Magnesium compounds (later referred to as magnesium salts) are a class of inorganic salts of great importance, and are one of the most important products exported by China, bringing a certain economic value to the national income every year.

Magnesium oxide whiskers were prepared by precursor sintering method using low-priced magnesium sulfate and sodium hydroxide as raw materials. Firstly, a single phase of the precursor basic magnesium sulfate [MgSO4-5 Mg(OH)2-2 H2O] with good crystallization and fibrous shape was produced by normal temperature reaction and hydrothermal crystallization using magnesium sulfate and sodium hydroxide as raw

Magnesium hydroxide is an important chemical product and intermediate, which can be used as flame retardant of rubber, plastic, fiber, resin and other polymer materials, wastewater neutralizer, flue gas desulfurization agent or coal solid sulfur agent, also can be used as electronic materials or pharmaceutical preparations. In the above applications, except for wastewater neutralization agent
