To address this challenge, CaZr4(PO4)6 + x wt% Al2O3 composite ceramics (CZPA, x = 0–25) are prepared by the solid-phase reaction method. when x = 5, the bulk density achieves the maximum value (3.17 g/cm3). Young's modulus reaches a maximum (58 GPa) at x = 5. The x- and y-axis shrinkages are in the range of 5.67%–8.67% and the z-axis shrinkage is in the range of 7.11%–9.91%. The coefficients of thermal expansion (CTE) gradually increase with the increase of Al2O3 doping and achieve a near-Si thermal expansion coefficient at x = 15, which means that it matches the thermal expansion of silicon wafers. This ceramic developed in this work is expected to be applied to multilayer-matched substrates matched to silicon.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-12-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770466","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 tribocatalytic process was initiated using magnetic stirring with a polytetrafluoroethylene-coated magnetic bar in a glass beaker setup. The degradation efficiency was evaluated at different stirring speeds of 300, 500, and 700 rpm. The results showed significant variation in degradation rates, with the highest degradation efficiency of ∼73% achieved within 12 h at a rotational speed of 700 rpm. Additionally, the impact of pH on the degradation process was examined by adjusting the dye solution to pH levels of 3, 6, and 9. The degradation efficiency increased with higher pH levels, with the maximum degradation occurring in the basic medium (pH 9). Kinetic analysis revealed that the degradation process adhered to pseudo-first-order kinetics, with rate constants of 0.023, 0.035, and 0.104 min⁻1 at different stirring speeds of 300, 500, and 700 rpm, respectively. This study showcases the potential of BST‒BZT ceramics as efficient tribocatalysts for degrading organic pollutants in wastewater, emphasizing the impact of stirring speed and pH on degradation efficiency.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770548","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}

A discrete element kinetic model for simulating the grinding process of SiO2 material was established. Through the quantitative analysis of energy conversion during grinding, the kinetic energy of particles, the kinetic energy of materials, and the energy consumed by materials were identified as three indicators for evaluating the grinding efficiency and performance of the ball mill. The optimal impeller structural parameters for improving the energy conversion efficiency of the ball mill were determined using the Taguchi method. The grinding efficiency and microstructure performance of the impeller type and traditional ball mills were compared. The results show that the energy loss between the materials and impeller accounted for the most significant proportion, about 30.4% of the total conversion energy. Based on the signal-to-noise ratio analysis, the optimum structural parameters of the impeller were obtained as follows: the height–diameter ratio of 1/2, blade thickness of 3 mm, inclination angle of 80°, and blade number of 5. Compared with planetary and horizontal ball mills, the average particle size of powders ground with the impeller-type ball mill improved by 8.16% and 11.38%, respectively, and the particle uniformity increased by 1.22% and 26.5%.","PeriodicalId":13903,"journal":{"name":"International Journal of Applied Ceramic Technology","volume":"22 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2024-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143770464","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 main purpose was to evaluate the effects of the minor phase on the properties of the composite materials. Commercial 8YSZ was the major phase. Pure LSGM and composites consisting of 1, 10, and 20 wt.% LSGM were prepared by the solid-state reaction method. Sintering experiments were carried out from 1200°C to 1450°C. The temperature of maximum shrinkage decreased with increasing LSGM content. The average grain size of the composites was dependent on the relative proportion of the minor phase. Interface reactions occurr during sintering. Electrical conductivity of the composites was found to be lower compared to that of 8YSZ.
