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.
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.
