High-thermal-expansion-coefficient high-strength low-temperature co-fired ceramic composite material as well as preparation method and application thereof
The invention relates to the technical field of ceramic materials, in particular to a high-thermal-expansion-coefficient high-strength low-temperature co-fired ceramic composite material and a preparation method and application thereof. The invention discloses a low-temperature co-fired ceramic composite material with a high thermal expansion coefficient and high strength. The low-temperature co-fired ceramic composite material contains a CaMgSi2O6 crystal phase, a BaAl2Si2O8 crystal phase and a cristobalite crystal phase, the thermal expansion coefficient of the ceramic composite material is greater than 10ppm/DEG C, and the dielectric loss is less than 0.001. According to the ceramic composite material disclosed by the invention, CaMgSi2O6 is generated by sintering and crystallizing the calcium aluminum magnesium barium titanium silicon glass, and the calcium aluminum magnesium barium titanium silicon glass has a relatively high thermal expansion coefficient; by adding SiO2, a cristobalite phase can be separated out, and the thermal expansion coefficient of the material is further increased while the dielectric constant of the material is reduced; by adding Al2O3, generation of a BaAl2Si2O8 phase is facilitated, the dielectric loss of the material is reduced, and the bending strength of the material is improved.
