Abstract

This review is devoted to describing the main synthesis methods, the properties of MgO nanoparticles, and their areas of application, such as the creation of coatings for transformer and other types of steels, coatings on glass to control the energy of transmitted solar radiation, the creation of transparent and translucent one-component ceramics, the creation of multicomponent ceramic compositions, in medicine to make antibacterial agents, etc. The main methods of obtaining MgO nanoceramics are considered: sintering at low temperatures under high pressure, high-temperature sintering, the spark plasma sintering (SPS) method, and obtaining MgO melt in plasma in a cooled crucible followed by crystallization and the formation of dense ceramics. It is shown that variations in the conditions for the synthesis of nanosized MgO powders make it possible to obtain precursors that, upon sintering, form ceramics with a density close to the theoretical one.

纳米氧化镁粉末的获得、性质和应用:概述

摘要

这篇综述专门描述了主要的合成方法、MgO 纳米粒子的性质及其应用领域,例如为变压器和其他类型钢制造涂层、在玻璃上涂层以控制透射太阳辐射的能量、制备透明和半透明的单组份陶瓷,制备多组份陶瓷组合物,在医药上制造抗菌剂等。 获得 MgO 纳米陶瓷的主要方法被认为是:低温高压烧结、高温烧结、放电等离子烧结 (SPS) 方法,在冷却的坩埚中获得等离子中的 MgO 熔体,然后结晶并形成致密的陶瓷。结果表明,纳米级 MgO 粉末合成条件的变化使得获得前体成为可能,这些前体在烧结后形成密度接近理论密度的陶瓷。
