Abstract:

The transformation of sunflower oil (SO) and waste cooking oil (WCO) into green diesel over co-precipitated nickel–zirconia catalysts was studied. Two series of catalysts were prepared. The first series included catalysts with various Ni loadings prepared using zirconium oxy-chloride, whereas the second series included catalysts with 60–80 wt % Ni loading prepared using zirconium oxy-nitrate as zirconium source. The catalysts were characterized and evaluated in the transformation of SO into green diesel. The best catalysts were also evaluated for green diesel production using waste cooking oil

The paper presents the results of research on the production of dense ceramics based on zirconium dioxide powder, the results of tests to study the physical and mechanical characteristics of samples, and microstructure studies. Experimentally, the composition of a suspension of zirconium dioxide powder on a water basis was selected. The apparent density of the samples obtained from the suspension after sintering was 5.91 g/cm3, the relative density was 97.7 %. The linear shrinkage of the sintered samples was 22 – 24 %. The bending strength of sintered prismatic samples reached 547 MPa. The mic

Abstract:

BACKGROUND: In recent years, zirconia prostheses have gradually become a mass type of orthopedic treatment. The production of zirconium dioxide blanks for dentistry has also been launched in our country. In recent years, the possibility of speed sintering of dental prostheses made of zirconia has been widely calculated, which makes it possible to reduce the process of manufacturing structures by four to five times. AIM: To investigate the effect of high-speed sintering on important properties, such as strength characteristics during three-point bending and color parameters at 10 differen

Abstract:

Zirconium amides have become increasingly popular and useful due to their widespread use as precursors to other zirconium complexes and their use in the production of solid oxide fuel cells (SOFCs). Herein we report the molecular structure of tris(dimethylamido)bis(dimethylamine)zirconium(IV) iodide, [Zr(C2H6N)3(C2H7N)2]I. The bond lengths and bond angles are consistent with a slightly distorted trigonal–bipyramidal coordination geometry around the metal atom. N...I contacts of 3.6153 (15) and 3.5922 (14) Å are consistent with the presence of N—H...I interactions. These N—H...I interactions li

Abstract:

The results of measuring the shrinkage of samples from ultrafine powders of zirconium oxides, aluminum and their mixtures in continuous air heating at a rate of 10 degrees /min in the range from 20 to 1650 oC are presented. The shrinkage curves and its rate are discussed from the perspective of the probable mechanisms of solid-phase sintering for each type of oxides and their mixtures. It was revealed that a solid solution of partially stabilized zirconium dioxide with yttrium oxide has increased activity to diffusion processes. This is manifested at a relatively low temperature of the beginni

Abstract:

Zirconium dioxide is a material known over 60 years, used for the production of ceramic and hybrid bearings and in dentistry: bows, crowns, and bridges. For testing the strength of zirconium dioxide, normative samples were made, which were subjected to strength tests. Microscopic analysis of sample fracture was performed. In addition, zirconium oxide is an easy to process material. Zirconium dioxide is a polymorphic material exhibiting three phases: monocyclic, cubic and tetragonal. In addition, during propagation of cracks, the material shows a strengthening transformation; replacement of pha

Abstract:

To date, reactor-grade zircon is produced on an industrial scale using metallothermic and electrochemical methods. Electrolytic production of reactor-purity zirconium in a sealed electrolyzer is more cost-effective than metallothermic production, as it does not require iodide refining and the use of reducing metals (Na, Mg, and Ca). Despite the importance of this production, its features are not fully described in the literature. This study presents the results of industrial tests of the electrolysis process in a sealed electrolyzer with a current load of 10 kA from the molten electrolyte KCl–

Abstract:

In ceramic industry, zircon sand is widely used in different applications because zirconia plays a role as common opacifying constituent. In particular, it is used as a basic component of glazes applied to ceramic tiles and sanitary ware as well as an opacifier in unglazed bulk porcelain stoneware. Natural zircon sands are the major source of zirconium minerals for industrial applications. In this paper, long, medium, and short range studies were conducted on zirconium minerals originated from Australia, South Africa, and United States of America using conventional and less conventional techni
