XRD, FTIR, SEM analyses and a ferroelectric tester were used to analyse the crystal structure, phase composition, microstructure and ferroelectric properties of the prepared ceramics. The results revealed that substitution of Ca 2+ by Sr 2+ in the HA lattice would lead to an increase in its lattice parameters and a decrease in crystallinity. Moreover, the lattice distortion and the increase in the electric dipole moment caused by the Sr 2+ doping enhanced the ferroelectric properties of the Sr-HA ceramics. Increasing the density of the samples could enhance their ferroelectric properties. The remnant polarisation intensity increased from 0.0156 μC∙cm-2 to 0.0728 μC∙cm-2, the maximum polarisation intensity increased from 0.1210 μC∙cm -2 to 0.1628 μC∙cm -2 .","PeriodicalId":9857,"journal":{"name":"Ceramics-silikaty","volume":"39 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78044280","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}

The hydration and early mechanical properties of this cement were characterised by isothermal calorimetry, a mechanical test, X-ray diffraction and a thermal analysis. The results showed that the optimal calcination temperature to obtain a satisfactory clinker strength was 1350 ℃ and the corresponding 1, 3 and 7-day strengths were 27.7, 45.8 and 54.3 MPa, respectively. The initial and final setting times of the cements range between 20 and 31 minutes. The cements had the characteristics of rapid hardening and the main hydration products were AFt, AFm and AH 3 . The total hydration heat release of this cement within the first 50 hours was only 158 J · g -1 , which could effectively avoid the generation of internal cracks in the cement and has the potential to be applied to large concrete projects. Furthermore, the MgAl 2 O 4 mineral phase was inert in the belite sulfoaluminate cement and did not participate in the hydration reaction, which eliminates the disadvantage of MgO in the cement systems and potentially increases the use of high magnesium limestone in cement production.","PeriodicalId":9857,"journal":{"name":"Ceramics-silikaty","volume":"100 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87877247","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}

The effects of the Na 2 O/K 2 O and R 2 O/Al 2 O 3 ratios on the surface energy and glossiness of the ceramic glaze were studied in the present work. The results show that the mass fraction ratio of Na 2 O/K 2 O and R 2 O/Al 2 O 3 showed an obvious effect on the high temperature viscosity and melting temperature of the glaze, the density of the glaze network structure and the number of broken bonds on the glaze. When Na 2 O/K 2 O = 0.8 – 1.6, R 2 O/Al 2 O 3 = 0.8 – 1.2, the glaze showed a glossiness of 88.3 – 108.3 with a 0.11 – 12 % increase, and the surface energy of 70.17 – 78.5 mJ·m -2 with a 5.62 – 29.55 % increase, being obviously higher than those of the basic glaze. The greater the surface energy of the glaze was, the greater the polarity component was, and the better the wettability of the water on the glaze was, which would be conducive to improving the antifouling and easy cleaning of ceramic products.","PeriodicalId":9857,"journal":{"name":"Ceramics-silikaty","volume":"29 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84974936","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}
