Abstract

The aim of the presented work is to investigate the effect of nano-quartz glazes which replaced the traditional powdered Quartz. These materials differed mainly in the specific surface area SA = 325 m² g⁻¹ for nano-quartz and SA = 1.41 m² g⁻¹ for quartz powder. Transparent glazes differing in the molar ratio of CaO/MgO equal to: 1:0/1:1/0:1 were used for the study. The impact on transparency and other surface properties of the glazes were determined. Measurements of the transparency of ceramic glazes were carried out using a new measurement technique. XRD and SEM analysis showed that all glazes were characterized by a high content (>90 %) of an amorphous phase and all glazes can be considered completely transparent. Using nano-quartz in the composition significantly improved all determined mechanical properties (Vickers hardness, Young's module, and fracture toughness coefficient). In addition, the glaze surface was smoother, and the alkaline durability was improved when using nano-quartz. Adding MgO enhanced the crystallization in the glaze, improving the chemical and mechanical properties whereas the transparency of the glaze was maintained.

纳米石英和CaO/MgO摩尔比对透明釉表面和力学性能的影响

本文的目的是研究纳米石英釉取代传统粉末状石英釉的效果。纳米石英的比表面积SA = 325 m2 g−1，石英粉的比表面积SA = 1.41 m2 g−1。采用CaO/MgO摩尔比为：1:0/1:1/0:1的透明釉进行研究。测定了其对釉料透明度和其他表面性能的影响。采用一种新的测量技术对陶瓷釉的透明度进行了测量。XRD和SEM分析表明，所有釉料都具有高含量（> 90%）的非晶相，可以认为所有釉料都是完全透明的。在成分中使用纳米石英显著改善了所有确定的机械性能（维氏硬度、杨氏模量和断裂韧性系数）。此外，使用纳米石英后，釉面更光滑，碱耐久性提高。MgO的加入促进了釉中的结晶，提高了釉的化学性能和力学性能，同时保持了釉的透明性。

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.
