Abstract
The invention provides a ceramic composite material and a super material prepared from the same. The super material comprises a substrate and microstructures which are periodically arranged on the substrate in an array mode, wherein the substrate is prepared from the ceramic composite material; and the ceramic composite material comprises the following components in percentage by mass: 94-97% of BaTiO3 main crystal phase, 1.4-3.5% of vitreous SiO2 and 1.4-3.5% of Al2O3. The dielectric constant of the substrate prepared from the ceramic composite material can reach 32 or so; and meanwhile, the lost tangent angle can be lowered to 0.0006 or so. The substrate of the super material prepared from the ceramic composite material is compact and uniform, has the advantages of favorable mechanical properties, high dielectric constant and low loss, and is suitable for popularization and use in the field of super materials.
Description
[technical field]
The present invention relates to super material field, relate in particular to the super material of a kind of ceramic composite and preparation thereof.
[background technology]
Super material refers to artificial composite structure or the matrix material that some have the not available extraordinary physical properties of natural materials.Structurally ordered design by on the key physical yardstick of material can break through the restriction of some apparent natural law, thereby obtains to exceed the meta-materials function of the intrinsic common character of nature.The character of super material and function mainly come from its inner structure but not constitute their material, therefore, are design and synthetic super material, and people have carried out a lot of research work.2000, people such as the Smith of Duke University pointed out that the composite structure of the metal wire of periodic arrangement and open loop syntonizer (SRR) can realize that DIELECTRIC CONSTANT and magnetic permeability μ simultaneously for negative two negative material, also claim LHM.They are again by making the two negative material that metal wire and SRR composite structure have been realized two dimension at printed circuit board (PCB) (PCB) afterwards.
The artificial microstructure of existing super material is generally metallic substance, and medium substrate generally adopts the organic resin substrate, the specific inductivity of organic resin baseplate material is generally between 3～5, and for some application of super material, often need than higher dielectric constant material as medium substrate, when satisfying various mechanical propertys, be difficult to search out suitable material.
If but use some high-ks, low-loss material, the product mechanical property of preparation is not only good, fine and close, even, also can be prepared into different shapes and satisfy industrial demand;
Medium ceramic material on the market comprises barium titanate and some oxide compounds, for example SrO, WO
3, PbO, B
2O
3Or rare earth etc., though the permittivity ratio of the substrate of this medium ceramic material preparation is higher, loss ratio is lower, but do not reach super material to the requirement of high-k (for example being not less than 30), simultaneously, the somewhat expensive for example rare earth of some oxide compound, also some oxide compound is poisonous, is not suitable for extensive use.
