Abstract

This study presents a fast and simple method for digital ceramic coloration using inkjet printing, eliminating the need for traditional precalcined pigments. This innovative approach represents a breakthrough in ceramic decoration technology, and introduces a previously unexplored methodology. In this work, CoAl₂O₄ spinel, a pigment commonly used in industrial contexts, is synthesized through laser zone melting (LZM) by applying pulsed laser radiation at 1064 nm. A standardized methodology to optimize pigment quality is developed, based on laser parameters such as pulse width, frequency, speed, power, and line spacing. Scanning electron microscopy (SEM) is used to determine the optimal laser conditions for obtaining a continuous, defect-free coating, showing that the embedded particles on the surface exhibit a nearly spherical morphology with diameters below 100 nm. The sample with the highest surface quality is further analyzed structurally and optically. X-ray diffraction (XRD) confirms the presence of a pure spinel phase without secondary phases, along with a vitreous phase due to pigment embedding. Fourier-transform infrared spectroscopy (FTIR) and Raman spectroscopy reveal the characteristic vibrational bands of a normal spinel structure. The intense blue color is confirmed by strong absorption at 560 nm in ultraviolet–visible (UV–Vis) spectroscopy, as well as b* and Δb* values of 29 and 1.58, respectively, compared to the traditional pigment. This synthesis approach significantly enhances digital ceramic coloration compared to other methods evaluated in this study, offering a scalable, flexible, and more efficient alternative suitable for industrial-scale production.

陶瓷工业中原位激光数字着色用蓝色颜料的超高速发展
本研究提出了一种使用喷墨印刷的快速简便的数字陶瓷着色方法,消除了对传统预煅烧颜料的需要。这种创新的方法代表了陶瓷装饰技术的突破,并引入了一种以前未被探索的方法。本文利用1064 nm脉冲激光辐射,通过激光区域熔化(LZM)合成了工业中常用的颜料CoAl₂O₄尖晶石。基于激光参数,如脉冲宽度、频率、速度、功率和线间距,开发了一种标准化的方法来优化颜料质量。利用扫描电子显微镜(SEM)确定了获得连续、无缺陷涂层的最佳激光条件,结果表明,表面上的嵌入颗粒呈直径小于100 nm的近球形形貌。对表面质量最高的样品进行进一步的结构和光学分析。x射线衍射(XRD)证实了无二次相的纯尖晶石相的存在,以及由于色素包埋而形成的玻璃相。傅里叶变换红外光谱(FTIR)和拉曼光谱揭示了正常尖晶石结构的特征振动带。通过紫外可见光谱(UV-Vis)在560 nm处的强吸收,以及与传统颜料相比,b*和Δb*值分别为29和1.58,证实了该颜料的强烈蓝色。与本研究中评估的其他方法相比,这种合成方法显著增强了数字陶瓷着色,提供了一种适用于工业规模生产的可扩展、灵活和更有效的替代方法。

期刊介绍: The Journal of the American Ceramic Society contains records of original research that provide insight into or describe the science of ceramic and glass materials and composites based on ceramics and glasses. These papers include reports on discovery, characterization, and analysis of new inorganic, non-metallic materials; synthesis methods; phase relationships; processing approaches; microstructure-property relationships; and functionalities. Of great interest are works that support understanding founded on fundamental principles using experimental, theoretical, or computational methods or combinations of those approaches. All the published papers must be of enduring value and relevant to the science of ceramics and glasses or composites based on those materials. Papers on fundamental ceramic and glass science are welcome including those in the following areas: Enabling materials for grand challenges[...] Materials design, selection, synthesis and processing methods[...] Characterization of compositions, structures, defects, and properties along with new methods [...] Mechanisms, Theory, Modeling, and Simulation[...] JACerS accepts submissions of full-length Articles reporting original research, in-depth Feature Articles, Reviews of the state-of-the-art with compelling analysis, and Rapid Communications which are short papers with sufficient novelty or impact to justify swift publication.
