Definitions
- the present invention relates to a glass ceramic material and a multilayer ceramic electronic component formed using the same.
- Patent Document 1 discloses an interesting technique for the present invention.
- Patent Document 1 describes a glass ceramic dielectric material used for semiconductor wiring boards, circuit boards and the like. More specifically, this glass ceramic dielectric material comprises 49.9 to 89.9% by weight of borosilicate glass powder, 10 to 50% by weight of alumina powder and / or quartz powder, and aluminum borate powder and And / or 0.1 to 4% by mass of silica borate compound powder.
- the glass ceramic dielectric material described above can be sintered at a relatively low temperature of, for example, 1000 ° C. or less, a low melting point and low conductor loss conductor material such as silver or copper to be a material for the electrode layer It has the advantage that it can be simultaneously sintered (co-sintered).
- a multilayer ceramic electronic component including a composite laminate in which a plurality of types of ceramic layers each composed of ceramic materials having different compositions are laminated, such as a composite electronic component.
- a composite electronic component In the production of such multilayer ceramic electronic components, not only can the ceramic material and the conductor material be co-sintered, but also multiple types of ceramic materials having different compositions can be co-fired to shorten the manufacturing process. It is desired to satisfy the desired characteristics.
- the composite laminate is configured using the glass ceramic dielectric material described in Patent Document 1, more specifically, among the first and second ceramic layers included in the composite laminate,
- the first ceramic layer is made of a glass ceramic dielectric material described in Patent Document 1 and the second ceramic layer is a magnetic layer made of, for example, ferrite, It is difficult to control interdiffusion between the ceramic layer and the second ceramic layer.
- the glass component diffuses from the first ceramic layer made of the glass ceramic dielectric material to the magnetic layer as the second ceramic layer.
- the diffusion of the glass component, particularly Si, into the magnetic layer reduces the sinterability of the ferrite.
- the magnetic layer becomes insufficiently sintered, and the insulation resistance characteristic of the multilayer ceramic electronic component including such a composite laminate may be deteriorated.
- an object of the present invention is to provide a glass ceramic material that can solve the above-described problems and a multilayer ceramic electronic component that is configured using the glass ceramic material.
- the present invention is first directed to a glass ceramic material that can be advantageously used to constitute a part of a composite laminate provided in a multilayer ceramic electronic component.
- the glass ceramic material according to the present invention is: 40 to 40% glass comprising 0.5-5% by weight K 2 O, 0-5% by weight Al 2 O 3 , 10-25% by weight B 2 O 3 , and 70-85% by weight SiO 2 90% by weight, 10-60 wt% filler, including alumina and quartz, including.
- the alumina contained in the filler is mainly characterized by containing 1 to 10% by weight of the total amount of glass and filler.
- the present invention also has a structure in which a first ceramic layer and a second ceramic layer having a composition different from that of the first ceramic layer are laminated and are obtained by co-sintering. Also directed to monolithic ceramic electronic components with a body.
- the present invention is characterized in that the first ceramic layer is made of a sintered body of the glass ceramic material according to the present invention.
- the glass viscosity of the glass ceramic material constituting the first ceramic layer increases during firing, thereby making it difficult for the glass component to diffuse from the first ceramic layer to the second ceramic layer. be able to. Further, along with this, component diffusion from the second ceramic layer to the first ceramic layer can be made difficult to occur.
- the present invention is particularly advantageously applied when the second ceramic layer is made of a ceramic magnetic material containing Ni—Cu—Zn based ferrite. Since ferrite has a tendency to lower the sinterability due to the diffusion of Si therein, as described above, the significance of suppressing the diffusion of the glass component into the second ceramic layer is significant.

- Undesirable interdiffusion has a greater influence on the electrical characteristics at the interface between the first ceramic layer and the second ceramic layer and in the vicinity thereof, more specifically, the insulation resistance. Therefore, as described above, if the interface between the first ceramic layer and the second ceramic layer exists on the path of the current flowing between the pair of terminal electrodes, the influence of mutual diffusion was exerted. Electrical characteristics such as insulation resistance appear between the paired terminal electrodes, leading to deterioration of the characteristics of the multilayer ceramic electronic component itself.

It is possible to make it difficult for the glass component to diffuse into the ceramic layer. Conversely, diffusion from the second ceramic layer to the first ceramic layer can also be made difficult to occur.
- the second ceramic layer is made of a ceramic magnetic material containing Ni—Cu—Zn-based ferrite
- the diffusion of the glass component here impedes the sinterability of the second ceramic layer. Therefore, it is easy to reduce the insulation resistance at the interface between the first ceramic layer and the second ceramic layer and in the vicinity thereof. Therefore, when the second ceramic layer is made of a ceramic magnetic material containing Ni—Cu—Zn-based ferrite, the above-described effect of suppressing the diffusion of the glass component becomes more significant.
