Abstract

The effect of the conditions of synthesis on the formation of micro- and nanoparticles of zirconium dioxide from a fluoride solution has been studied. It is shown that the finest particles are formed by precipitation from dilute solutions with a zirconium concentration of 0.02–0.04 mol/L and impurities of polyvinyl alcohol at a mass ratio of mZr : mPVC 1 : 0.1. To sinter ZrO2 nanoparticles, it is proposed to use the electroconsolidation method in a vacuum to obtain ceramics with high values of the hardness and elastic modulus.

氟化溶液中ZrO2微粒子和纳米粒子合成粉体的形成和烧结研究
研究了合成条件对氟化物溶液中二氧化锆微粒子和纳米粒子形成的影响。结果表明,在锆浓度为0.02 ~ 0.04 mol/L的稀溶液中,以mZr: mPVC 1:1 .1的质量比沉淀聚乙烯醇杂质,可得到最细的颗粒。为了烧结ZrO2纳米颗粒,提出了在真空条件下采用电固结法制备高硬度和高弹性模量的陶瓷。

期刊介绍: Journal of Superhard Materials presents up-to-date results of basic and applied research on production, properties, and applications of superhard materials and related tools. It publishes the results of fundamental research on physicochemical processes of forming and growth of single-crystal, polycrystalline, and dispersed materials, diamond and diamond-like films; developments of methods for spontaneous and controlled synthesis of superhard materials and methods for static, explosive and epitaxial synthesis. The focus of the journal is large single crystals of synthetic diamonds; elite grinding powders and micron powders of synthetic diamonds and cubic boron nitride; polycrystalline and composite superhard materials based on diamond and cubic boron nitride; diamond and carbide tools for highly efficient metal-working, boring, stone-working, coal mining and geological exploration; articles of ceramic; polishing pastes for high-precision optics; precision lathes for diamond turning; technologies of precise machining of metals, glass, and ceramics. The journal covers all fundamental and technological aspects of synthesis, characterization, properties, devices and applications of these materials. The journal welcomes manuscripts from all countries in the English language.
