Problems solved by technology

However, the chemical synthesis method and the use of ultra-fine powder will lead to complex process, sharp increase in manufacturing cycle and cost
In comparison, adding low-melting glass, compounds or oxides that match the material matrix will lead to a decrease in the microwave performance of the matrix material, but the process is simple and easy to achieve industrial production
However, the composition of the low-melting point glass itself is relatively complex, and the production cost is high. It requires professional equipment for high-temperature melting of the glass, and the heat treatment takes a long time and consumes a lot of energy.
Moreover, the cold quenching process of glass has a large loss of equipment, the glass slag after quenching has high hardness, it is difficult to grind, the shape of the glass is poor, and the process adaptability is not good

Abstract

The invention discloses a medium low temperature co-fired ceramic material and a preparation method thereof. The medium low temperature co-fired ceramic material comprises 40-65 parts by mass of a Ba-Zn-Ti compound, 35-55 parts by mass of powder A and 0-5 parts by mass of powder B, wherein the powder A is a pre-sintered body obtained by firing the following components in parts by mass: 0-15 partsof SiO2, 0-65 parts of BaCO3, 15-55 parts of H3BO3, 0-15 parts of ZnO and 0-70 parts of Bi2O3; and the powder B is one or a combination of more of Co3O4, MnCO3, SrTiO3, La2O3, CuO and Cr2O3. The material is not reacted with silver, and can be widely applied to manufacturing multilayered dielectric resonators, microwave antennas, filters and other microwave devices. Moreover, the raw materials usedby the material are rich, the cost is low, the preparation process is simple, and industrial production is facilitated.

Description

technical field [0001] The invention relates to the technical field of ceramic materials, in particular to an intermediate low-temperature co-fired ceramic material and a preparation method thereof. Background technique [0002] The rapid development of miniaturization and light weight of electronic equipment has put forward higher requirements for microelectronic devices and integrated devices, and the integration of a single active device has been unable to meet production applications. With the advent of the 5G era, mobile communications, Internet of Things, automotive electronics, medical electronics, aerospace and military electronics and other fields will be upgraded accordingly, and the miniaturization of passive devices is imminent. [0003] Low temperature co-fired ceramic (Low Temperature Co-fired ceramic, LTCC) technology can make the device maintain excellent high-frequency characteristics on the basis of high integration, and has become a main way to realize the...
