Embodiment 1

[0028] Table 3 shows the content of each component of the specific example 1 of the present invention. Each material was weighed according to the mass percentage, and after 4 hours of mixing, the binder was added to granulate, and pressed at 120MPa. The sample was directly kept at 685°C for 40 minutes, then taken out directly and cooled at room temperature. The performance test of the sintered body is shown in Table 4.

Abstract

The invention relates to a low-temperature rapid firing high-frequency low-loss glass ceramic and a preparation method thereof. The glass ceramic is sintered from silicon boron, borosilicate glass, a nucleating agent and a binder. By using the ingredients of the present invention, low-temperature melting of calcium-silicon-boron and borosilicate glasses can be realized, the glass frit can be sintered at about 680°C, and the sintered body has excellent dielectric properties (εr is 6-8, tanδ<0.0005 25MHz).

Description

technical field [0001] The invention relates to a low-temperature rapid firing high-frequency low-loss glass ceramic and a preparation method thereof, belonging to the field of ceramic materials. Background technique [0002] Low-temperature rapid sintering technology is the development trend of various ceramic products preparation technology. Low-temperature rapid sintering technology can greatly reduce energy consumption, improve production efficiency, reduce costs, expand raw material sources and many other advantages. All over the world, whether it is daily-use ceramics or ceramic products used in high-tech fields, researchers are working hard to reduce the firing temperature and shorten the firing cycle, but the performance of the obtained products is similar to that of traditional methods, or even superior. in traditional products. Low temperature co-fired ceramics (Low Temperature co-fired Ceramics, LTCC) technology is one of the important applications of low temper...
