Low-temperature co-fired ceramic material as well as preparation method and application thereof

The invention discloses a low-temperature co-fired ceramic material as well as a preparation method and application thereof, and belongs to the technical field of electronic functional materials and devices. Amorphous SiO2 and Al2O3 are mixed to serve as a ceramic main phase, and the dielectric constant of the low-temperature co-fired ceramic material is regulated and controlled through a dielectric constant mixing rule; the low-melting-point crystalline hydrate aK2O-bNa2O-cB2O3 is used as a sintering aid, so that the sintering temperature of the low-temperature co-fired ceramic material can be regulated and controlled; by adding the density control agent, the density of the low-temperature co-fired ceramic material can be regulated and controlled; according to the low-temperature co-fired ceramic material disclosed by the invention, the low-temperature co-fired ceramic material meeting the basic requirements of a dielectric material of an existing high-frequency high-Q laminated inductance component can be o
