摘要

玻璃纤维是以赤泥为主要原料生产的。考察了ZrO2含量对玻璃纤维的网状结构、拉伸强度和耐碱性能的影响。结果表明：随着ZrO2含量的增加，玻璃网的聚合度呈现先升高后降低的趋势；玻璃网状结构的改变引起了抗拉强度的变化，当ZrO2含量增加到1.0 wt%时，抗拉强度达到最大值1927±34 MPa。扫描电镜（SEM）和能量色散x射线能谱（EDS）分析表明，适当添加ZrO2后，Zr4+参与了玻璃网络的构建，在侵蚀环境下，以Zr4+离子作为锚点在玻璃纤维表面形成保护壳，显著增强了玻璃纤维的耐腐蚀性。

Effect of ZrO2 content on the structure and alkali resistance of glass fibers prepared from red mud

Glass fibers are manufactured using red mud as the primary raw material. The effect of ZrO₂ content on the glass network structure, tensile strength, and alkali resistance of the glass fibers was examined. The results indicated that the degree of polymerization of the glass network exhibited an initial increase followed by a decrease with rising ZrO₂ content. The change in glass network structure causes a change in tensile strength, as the ZrO₂ content increased to 1.0 wt%, the tensile strength reached the maximum of 1927 ± 34 MPa. Scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) analyses revealed that, with the appropriate addition of ZrO₂, the Zr⁴⁺ participates in the construction of glass network, using Zr⁴⁺ ions as anchor points to form a protective shell on the surface of glass fibers in an erosive environment significantly enhances the corrosion resistance of glass fibers.

期刊介绍： Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties. Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour. Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
