Outline of Final Research Achievements

On the wireless communication, high frequency such as millimeter-wave is expected for 5G, because high frequency brings high rate data transfer. The materials are expected high Q and low dielectric constant, the former is needed for high frequency because alternate current of electromagnetic wave brings dielectric losses, and on the later, shortening of wave length based on dielectric constant is not needed because of short wave length of millimeter. The low dielectric constant rather is needed for time delay which brings short time delay. Silicate are candidate for millimeter-wave dielectrics because of low dielectric constant based on the SiO4 tetrahedron with 50% covalency. In particular, indialite glass ceramics have high Qf of > 200,000 GHz, and low dielectric constant of 4.7. Here, indialite is one of polymorph of cordierite. Pure indialite powder had been applied for LTCC substrates.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義は、結晶学に基づいて研究を進めている点にある。Cordieriteの高温型であるindialiteが高いマイクロ波誘電特性を持つ、その転移温度はcordieriteが分解溶融する近傍にあり、固相反応では合成が難しい。一方、indialiteはガラスの結晶化途中に析出する、それ故、合成はガラスからの結晶化に依った。
現在、ワイヤレス通信は、5Gに向けて、大容量伝送が可能なミリ波帯に注目が集まっている。ケイ酸塩は、誘電率が低いのでミリ波帯の誘電体として期待されている。Indialiteは、低誘電率、高Qfを持つのでミリ波誘電体材料として有望視されている。
