Microwave welding ceramic materials
 Two or more materials (same or different ) by atomic or molecular binding between a permanent connection and a diffusion process is called soldering.
  In order to achieve the welding process , to make two or more objects to be welded to each other close to the interatomic or intermolecular forces , the degree can take place , that is, to close to the image or between the atoms of the material as the distance between molecules . Accordingly , the welding requires the use of heat, pressure or pressure while heating method to induce the material to be welded two atoms capable of binding to the extent of up to obtain a permanent firm connection .
Welding technology is the late 19th early 20th century to develop. Because it has a range of technical and economic advantages , so the development of fast, 60 years later, with the development of industry , welding of new energy development and new welding processes
Applications with greater progress , there are dozens of welding methods .
 Soldered at high temperatures, the use of microwave ceramics in recent years, the development of a new technology, which uses microwave dielectric loss in the material of the ceramic heating under pressure the connections . According to whether to join the joint between the intermediate medium , microwave welding can be divided into direct and indirect welding two kinds of welding . The heating of the ceramic material by the interaction of the microwave , and the joint can be uniformly connected to avoid crack occurrence . Meanwhile, the fast heating rate of microwave heating , the ceramic will not be intense internal grain growth , grain boundary phase element distribution more uniform than before welding , the joint region so that the material can maintain excellent performance.
