Bulk inorganic materials play important roles in human society, and their construction is commonly achieved by the coalescence of inorganic nano- or micro-sized particles. Understanding the coalescence process promotes the elimination of particle interfaces, leading to continuous bulk phases with improved functions. In this review, we mainly focus on the coalescence of ceramic and metal materials for bulk construction. The basic knowledge of coalescent mechanism on inorganic materials is briefly introduced. Then, the properties of the inorganic precursors, which determine the coalescent behaviors of inorganic phases, are discussed from the views of particle interface, size, crystallinity, and orientation. The relationships between fundamental discoveries and industrial applications are emphasized. Based upon the understandings, the applications of inorganic bulk materials produced by the coalescence of their particle precursors are further presented. In conclusion, the challenges of particle coalescence for bulk material construction are presented, and the connection between recent fundamental findings and industrial applications is highlighted, aiming to provide an insightful outlook for the future development of functional inorganic materials.
块状无机材料在人类社会中发挥着重要作用，其构建通常通过无机纳米或微米级颗粒的聚结来实现。了解聚结过程有助于消除颗粒界面，从而形成具有改进功能的连续块状相。在本综述中，我们主要关注用于块状构建的陶瓷和金属材料的聚结。简要介绍了无机材料聚结机制的基础知识。然后，从颗粒界面、尺寸、结晶度和取向的角度讨论了决定无机相聚结行为的无机前驱体的性质。强调了基础发现与工业应用之间的关系。基于这些认识，进一步介绍了由其颗粒前驱体聚结产生的无机块状材料的应用。总之，提出了块状材料构建中颗粒聚结的挑战，并突出了近期基础研究成果与工业应用之间的联系，旨在为功能性无机材料的未来发展提供有见地的展望。
