The most developed facets of the original diamond crystals are the octahedral {111} and cubic {100} faces. It is established that graphitization begins from the vertices and edges of crystals. {111} faces are more susceptible to graphitization than {100} faces. The morphological analysis of graphitized diamond AC160 in air helps us to study the kinetics of graphitization: the growth of dendritic graphite crystals and the formation of “graphitization pits” on the surface of diamond facets. It is shown for the first time that graphite of different shapes is formed on different diamond faces at different rates; thus, on the {111} faces graphite forms and grows in the form of triangles, and on the {100} faces, in the form of squares. At a high temperature, the volumetric graphitization of diamond particles is observed, accompanied by their destruction, mainly in the growth stages.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"50 2","pages":"69 - 86"},"PeriodicalIF":0.8,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142413645","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In ultrasonic-assisted hydrothermal synthesis, the reaction parameters such as boron source, reaction temperature and time were optimized. The synthesis was achieved in the modest conditions of 60°C—2.5 min and 70°C—15 min for the boron sources borax and tincalconite, respectively. The obtained phases were identified as the compound of copper borate (Cu(BO2)2) with the powder diffraction file no. 00-001-0472. The reaction yields were also increased from 48 to 75% with modification of experimental procedure. The observed characteristic stretchings in spectral analyses proved the functional groups of three and four coordinated boron to oxygen bands. In the morphological analyses, less agglomerates were observed at the samples produced by using the boron source of borax than tincalconite. The results exhibited the beneficial effects of probable usage of the ultrasound energy on both the practical synthesis and the increase of characteristics.","PeriodicalId":580,"journal":{"name":"Glass Physics and Chemistry","volume":"50 2","pages":"168 - 173"},"PeriodicalIF":0.8,"publicationDate":"2024-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142413794","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
