Abstract

The directional solidified eutectic (DSE) ceramics have various potential applications such as aerospace industry, gas turbines, heat-resistant sensor, nanotechnology, electronics and Light-Emitting Diodes (LEDs) due to the higher strength, almost constant, up to temperatures close to the melting point and a better creep resistance. In this review, main advances produced in crystal growth techniques during recent years have been presented. The most commonly used methods for growth of eutectic ceramics and are discussed, including Bridgman technique, Edge-defined Film-Fed growth technique, Czochralski technique and Micro Pulling-Down technique. In addition, we introduced the microstructure and morphology control and their crystallographic orientation. The paper also explores mechanical properties (Residual stresses, Elastic modulus, Hardness and Fracture toughness) of eutectic ceramics. This review aims to summarize recent progress in the fabrication and application of various eutectic ceramics.

定向凝固共晶陶瓷的发展与应用综述

定向凝固共晶（DSE）陶瓷由于具有较高的强度、几乎恒定的温度、接近熔点的温度和更好的抗蠕变性能，在航空航天工业、燃气轮机、耐热传感器、纳米技术、电子和发光二极管（led）等领域具有各种潜在的应用。本文综述了近年来晶体生长技术的主要进展。讨论了常用的共晶陶瓷生长方法，包括Bridgman法、边缘限定膜式生长法、Czochralski法和微下拉法。此外，我们还介绍了微观结构和形态控制及其晶体取向。本文还探讨了共晶陶瓷的力学性能（残余应力、弹性模量、硬度和断裂韧性）。本文综述了近年来各种共晶陶瓷的制备和应用进展。

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.
