Description
Technical field
The invention belongs to electronic ceramic dielectric material technical field, more particularly to a kind of microwave ceramic dielectric material and preparation
Method.
Background technology
Microwave dielectric ceramic materials are low with being lost, and frequency-temperature coefficient is small, the features such as dielectric constant is high.Use microwave-medium
All kinds of high performance devices that ceramic material is made, have been widely used in satellite television, radar, mobile communication, electronic computer
And show the various fields such as medical science.Microwave-medium ceramics are the passes of the microwave devices such as resonator, wave filter, oscillator, phase shifter
Key material, and the performance of microwave-medium ceramics largely determines the size and performance of above-mentioned component and system
The limit.
The existing manufacturer production in the country porcelain, but have dielectric constant is small, temperature coefficient is big, loss is big, performance is unstable etc.
Shortcoming, it is impossible to be used in it is required that tighter occasion.
The content of the invention
Big it is an object of the invention to provide a kind of dielectric constant, it is micro- that temperature coefficient is small, insertion loss is small and performance is stable
Ripple ceramic medium material.
The purpose of the present invention is achieved through the following technical solutions, and the microwave ceramic dielectric material is by following raw material system
Into：Barium carbonate (BaCO3) 30~60%, zirconium oxide (ZrO2) 20~40%, tin oxide (SnO2) 20~40%, tungsten oxide (WO3)
0.2~1%, yittrium oxide (Y2O3) 0.2~1%, chrome green (Cr2O3) 0.1~0.6%, dysprosia (Dy2O3) 0.1~
0.6%。

Its preparation technology is：After raw material are bought, by carrying out the dispensing of base-material after the assay was approved, by ball milling, press filtration,
Dry, calcine, crush, except techniques such as iron, obtain base-material stand-by；Then finished product material dispensing can be carried out, then by ball milling, stirring
Mill, batch mixing, mist projection granulating, get product material except iron, batch mixing, after the assay was approved packaging and storage.
The present invention is Ba-Zr-Sn base porcelains, by adding WO3, Y2O3, Cr2O3, Dy2O3 acceleration of sintering, reduction sintering
Temperature, reaches porcelain body grain refining, so as to improve dielectric constant, reduce loss and temperature coefficient；The main feature of the present invention
It is 1, adds a small amount of W ion when BaZrSn agglomerates are synthesized, the dielectric constant of porcelain can be significantly improved；2nd, Y is used2O3、Cr2O3、
Dy2O3It instead of conventional cerium oxide (CeO2), niobium pentaoxide (Nb2O5), the component such as lanthana (La2O3), further carrying
High-k, promote porcelain body grain refining, improve dielectric constant, reduction loss, improve temperature characterisitic in terms of have obvious effect.
