Abstract

CaO-Al₂O₃-SiO₂ mixed powder and glass were used as the joining materials to join SiC ceramics by induction heating in a joining temperature range of 1400–1600 °C under pressureless condition with heating and cooling rates of 100 °C/min. The joint prepared with CaO-Al₂O₃-SiO₂ mixed oxide powder as joining material has the highest shear strength of 60.09 ± 6.22 MPa at joining temperature of 1500 °C, which contains triclinic CaAl₂Si₂O₈ crystalline phase generated by chemical reaction in the holding process. In contrast, the joint produced with CaO-Al₂O₃-SiO₂ glass powder at 1500 °C also has the highest shear strength of 75.76 ± 2.34 MPa, which contains hexagonal CaAl₂Si₂O₈ and quartz generated through crystallization in the holding process due to rapid cooling rate of induction heating. In this study, the feature of mixed powder and glass joining by the induction heating technology was discussed to provide an effective and economic method for ceramic joining.

基于感应加热的碳化硅陶瓷与 CaO-Al2O3-SiO2 混合粉/玻璃的接合

以 CaO-Al2O3-SiO2 混合氧化物粉末和玻璃为接合材料，在 1400-1600°C 的接合温度范围内，在无压条件下，以 100°C/min 的加热和冷却速率，通过感应加热接合 SiC 陶瓷。用 CaO-Al2O3-SiO2 混合氧化物粉末作为接合材料制备的接合点在接合温度为 1500°C 时的剪切强度最高，为 60.09 ± 6.22 MPa，其中含有在保温过程中通过化学反应生成的三菱系 CaAl2Si2O8 结晶相。相比之下，在 1500°C 下使用 CaO-Al2O3-SiO2 玻璃粉生产的接头的剪切强度也最高，为 75.76 ± 2.34 MPa，其中含有六方的 CaAl2Si2O8 和石英，它们是在保温过程中由于感应加热的快速冷却速度而结晶生成的。本研究探讨了利用感应加热技术连接混合粉末和玻璃的特点，为陶瓷连接提供了一种有效而经济的方法。

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.
