Influence of the pH Value on the Changes in the Particle Size in the Process of Hydrolysis of Sulphated Zirconium

In this work, we studied the effect of the pH value on the change in particle size during the hydrolysis of sulfated zirconium. It has been established that mainly small particles are formed. The presence of large particles is also observed, which probably consist of smaller ones

STUDY OF THE EFFECT OF THE VALUE OF PH ON THE SHAPE AND SIZE OF ZIRCONIUM DIOXIDE PARTICLES STABILIZED WITH A MIXTURE OF REE

The work is aimed at investigating the pH value of precipitation on the size and shape of zirconium dioxide particles stabilized with a mixture of REE. It is shown that an increase in the pH value leads to a decrease in the average particle size, when the particle shape becomes more rough

INFLUENCE OF THE SALT BACKGROUND ON THE PROPERTIES OF LAYERED GADOLINIUM HYDROXONITRATES, OBTAINED BY THE PRECIPITATION METHOD AT A CONSTANT VALUE OF PH

The work shows that the salt background has a significant effect on the process of precipitation of gadolinium hydroxonitrate: at a salt concentration below 5 M, the formation of particles occurs in a layer-by-layer buildup mode; at a concentration above 5 M, layered build-up does not occur. The properties of gadolinium hydroxonitrate particles are also largely determined by the nature and concentration of the salt background

THE PRODUCTION OF LAYER YTTRIUM HYDROXONITRATES WITH CONTROLLED PROPERTIES

The work shows that the pH value of the precipitation has a significant effect on the yttrium hydroxonitrates properties. It is shown that at pH =8 particles have a regular shape close to spherical that is caused by layer-by-layer build-up of nucleus during precipitation

INFLUENCE OF pH ON THE STRUCTURING OF LAYERED GADOLINIUM HYDROXONITRATES

A study of the effect of pH on the formation process of gadolinium hydroxonitrate was made. As a result, it was found that precipitation at a constant pH in the range from 7,6 to 9,2 results in structured particles. While precipitation at higher or lower pH values results in the formation of gelatinous sediments

ANTIOXIDANT ACTIVITY OF CERIUM OXIDE NANOPARTICLES IN THE MALTODEXTRIN SHELL

The study on antioxidant activity of the maltodextrin-coated cerium oxide nanoparticles was carried out. CeO[под]2 nanoparticles exhibit properties that mimic natural antioxidant enzymes (catalase and peroxidase) and are capable of neutralizing hydroxyl radicals

STUDY OF THE EFFECT OF VALUE PH DEPOSITION ON THE PROPERTIES OF ZIRCONIUM DIOXIDE STABILIZED BY YTTRIUM OXIDE

The work is aimed at studying the influence of the pH value of precipitation of hydrated zirconia with the addition of yttrium as a stabilizing component. It was shown that the deposition pH affects the morphology and particle size distribution of the obtained oxides
