To improve impregnation of the carbon-graphite by an autoclave-free technique, coatings that form the eutectic with aluminum were used. Investigation of the effect of impregnation temperature showed that increasing the impregnation temperature with AK12 alloy to 750°C led to filling of 43.57% of the open pores of the carbon-graphite pre-plated with copper, while for nickel-plated samples this value was 37.32%. With a further increase of the temperature to 800°C, pore filling increased to 72.27% for the copper-preplated samples and to 66.25% for the nickel-plated samples. Using an Al–Mg–Zn–Cu alloy at an impregnation temperature of 750°C, pore filling of the pre-coppered samples reached 56.87%, and of the pre-nickel-plated carbon-graphite samples 49.25%. It was found experimentally that the copper coating is more effective at improving infiltration of the matrix aluminum alloys than the nickel coating. Analysis of the chemical composition of carbon-graphite impregnated with the Al–Mg–Zn–Cu alloy revealed chemical inhomogeneity of the metal alloy composition in the pores, manifested as segregation of the more active elements (magnesium, zinc) of the matrix alloy toward the interfacial zone with the carbon-graphite. It was established that with increasing degree of pore filling by the matrix alloy, the physicomechanical properties increase (compressive and flexural strength, wear resistance, and specific electrical resistivity of the composite).","PeriodicalId":586,"journal":{"name":"Inorganic Materials: Applied Research","volume":"17 5","pages":"1434 - 1440"},"PeriodicalIF":0.4,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149022983","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In another case, the graphene sheets were deposited on ceria nanocrystallites by combining the suspensions of ceria and graphene in an isopropanol-aqua mixture. It was found that the introduction of less than 1 wt % graphene leads to a decrease in the sintering temperature of nanocrystalline ceria by 175°C if the composite was obtained from a Ce-containing sol, and by 212°C if a nanocrystallite ceria was used for this purpose.

The composition was supplemented with TiO2 nanoparticles measuring ~200 nm. Polysaccharide-based films containing TiO2 nanoparticles exhibit enhanced strength properties compared to the original films.

The samples are synthesized using a two-stage solid-state reaction method with preliminary mechanoactivation. X-ray diffraction analysis reveals that all samples feature a perovskite-like structure with minor impurity phases. Increasing the Zr4+ concentration leads to broadening of diffraction peaks and the appearance of diffuse maxima; this may indicate modulation effects and inhomogeneous cation (Zr4+, Ti4+, Nb5+) distribution.

The shape, size and number of Bi nanocrystals were determined by intelligent image analysis. Most Bi nanocrystals condensed at 10 s deposition time on the sapphire (1(bar {1})02) substrates exhibited hexagonal and rhombohedral shapes, indicating the influence of a low temperature gradient at the nanocrystal–substrate interface and of physicochemical interaction with the sapphire substrate, which has a similar structure. The increase of the deposition time from 10 to 20 s increased the sizes of most condensed Bi nanocrystals from 20–40 to 30–90 nm and promoted formation of the microcrystals with the sizes up to 160 nm. Regions with a two-layer structure of Bi crystallites were observed for the deposition times more than 15 s. At the deposition times of 15 and 20 s, Bi nanodisks and microdisks condensed on the sapphire surfaces with their flat faces oriented perpendicular to the substrate surface. This orientation of disk‑shaped crystallites is a result of the thermal conductivity anisotropy of Bi and the high thermal conductivity of sapphire, which affect the condensation process with the increase of the temperature gradient at the crystallite–substrate boundary due the rise of heat flow from the evaporating Bi atoms. X‑ray patterns of the samples confirmed the hexagonal structure of the Bi crystallites with an orientation consistent with the structures of Bi and the sapphire substrate, and also revealed Bi2O3 on their surfaces, formed by interaction with oxygen on the substrate surface and in the atmosphere during storage.","PeriodicalId":586,"journal":{"name":"Inorganic Materials: Applied Research","volume":"17 5","pages":"1213 - 1218"},"PeriodicalIF":0.4,"publicationDate":"2026-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149023266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
