摘要

目的研究由沙子、高岭土和长石混合物制成的瓷器的介电性能。后者部分由固体重晶石废料(SBWs)替代。研究方法。研究采用传统的固态反应方法制备瓷器,采用两种烧制温度(1200 和 1300 °C),浸泡时间为 3 小时。在混合物中逐步添加 SBW,添加量分别为 0、10、20 和 30 wt%,以取代长石含量。进行了结构和介电特性分析,以研究 SBWs 替代对宏观介电特性的影响。微观结构观察发现了各种结晶相和微孔,它们对性能的影响功不可没。在 1200 °C 烧结后,主要矿物相包括莫来石、阳起石和石英。在 1300 ℃ 时,长石相与正长石和石英相同时出现。测定了所生产瓷器样品的技术属性,包括稀释特性、表观密度和孔隙率。研究结果。在 102-105 Hz 频率范围内进行的介电特性分析表明,在 1200 °C 下烧结的样品,相对常数介电常数值从 4.3 上升到 7.4,在 1300 °C 下烧结的样品,相对常数介电常数值从 5.1 上升到 9.9。此外,介电损耗正切随烧结温度的升高而减小。瓷土的宏观介电常数可通过混合法则精确计算,这与实验结果非常吻合。原创性。该研究的原创性在于利用布凯德矿的 10 wt% 固体重晶石废料(SBWs)来有效制造环保型瓷绝缘体。这项研究展示了固体重晶石废料作为部分替代品的潜力,从而促进了瓷绝缘体生产的可持续性。实用价值。这项研究的结果对陶瓷和绝缘体制造行业具有实际意义,因为它提供了通过加入生丁橡胶来提高瓷绝缘体介电性能的见解。这种方法有助于生产环保型绝缘体。

Recycling of barite ore tailings into porcelain: microstructure and dielectric properties
Purpose. To study the dielectric properties of porcelain obtained from a mixture of sand, kaolin, and feldspar. The latter has been partially substituted with solid barite wastes (SBWs). Methodology. The study involves preparation of porcelain using conventional solid-state reaction methods, employing two firing temperatures (1200 and 1300 °C) and a soaking time of 3 hours. SBWs are progressively added to the mixtures at levels of 0, 10, 20 and 30 wt%, replacing feldspar content. Structural and dielectric characterizations are conducted to examine the influence of SBWs substitution on macroscopic dielectric properties. Microstructural observations reveal various crystalline phases and micropores, contributing to property effects. Following sintering at 1200 °C, primary mineralogical phases include mullite, anorthite, and quartz. At 1300 °C, the celsian phase emerges alongside anorthite and quartz phases. The technological attributes of the produced porcelain samples, encompassing dilatometric properties, apparent density, and porosity, are determined. Findings. Dielectric characterization, conducted within the frequency range of 102–105 Hz, demonstrates that the relative constant permittivity values rise from 4.3 to 7.4 for samples sintered at 1200 °C and from 5.1 to 9.9 for those fired at 1300 °C, specifically for samples containing 10 wt% SBWs. Additionally, the dielectric loss tangent decreases with increasing sintering temperature. The macroscopic permittivity of porcelains can be accurately calculated using a mixing rule, which aligns well with experimental results. Originality. The original contribution lies in the use of 10 wt% Solid Barite Wastes (SBWs) from the Boucaid mine in order to effectively create environmentally friendly porcelain insulators. The study showcases the potential of SBWs as a partial substitute, thus promoting sustainability in porcelain insulator production. Practical value. The results of this study hold practical significance for the ceramics and insulator manufacturing industries by providing insights into enhancing the dielectric properties of porcelain through the incorporation of SBWs. This approach contributes to the production of environmentally friendly insulators.
