The flame retardant effect of metal hydroxide is mainly the release of water by heat absorption and decomposition, when it is added to the polymer with high filling amount, the flame retardant polymer is brought by metal hydroxide when it is decomposed by heat – a series of physical effects: the release of water and […]

Highlights •Antimicrobial nanoparticles (NPs) are widely used in dental materials to improve their biological properties. •Magnesium Oxide (MgO) NPs are novel antimicrobial agents. •Incorporation of MgO NPs in dental cements aids in minimizing bacterial colonization at the restoration margin. •Zein polymer facilitates the dispersion of MgO NPs and avoid its agglomeration. •Zein polymer effectively enhances the

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

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.
