Abstract
In the present paper, we report data on the influence of choice of dispersion medium-precipitating agent pair on sol–gel process for lead zirconate-titanate ceramic precursor manufacturing. Acetic acid and 2-methoxyethanol were studied as dispersion media, whereas ethylene glycol and water as respective precipitating agents. Changes in optical, rheological properties and particle size distributions during the sol–gel transition were studied at different concentrations of precipitating agents. It was shown that the nature and relative concentration of dispersion medium and precipitating agent provide wide-range control of lead zirconate-titanate sol and gel properties as well as the rate of sol–gel process, mechanism of formation and structure of the gels.
期刊介绍：
Colloid Journal (Kolloidnyi Zhurnal) is the only journal in Russia that publishes the results of research in the area of chemical science dealing with the disperse state of matter and surface phenomena in disperse systems. The journal covers experimental and theoretical works on a great variety of colloid and surface phenomena: the structure and properties of interfaces; adsorption phenomena and structure of adsorption layers of surfactants; capillary phenomena; wetting films; wetting and spreading; and detergency. The formation of colloid systems, their molecular-kinetic and optical properties, surface forces, interaction of colloidal particles, stabilization, and criteria of stability loss of different disperse systems (lyosols and aerosols, suspensions, emulsions, foams, and micellar systems) are also topics of the journal. Colloid Journal also includes the phenomena of electro- and diffusiophoresis, electro- and thermoosmosis, and capillary and reverse osmosis, i.e., phenomena dealing with the existence of diffusion layers of molecules and ions in the vicinity of the interface.
