This is why current dielectric LTCC materials have such low εr and Q values.
The only previously reported example of such materials is (ZnCu2)Nb2O8, found as in intergranular phase when CuO was added to zinc niobate ZnNb2O6 [2].

But following the booming development of new science and technology revolution in world，the high performance materials have been required extensive and urgent.
EXPERIMENTAL Materials PES was obtained from the chemistry department of Jilin university .The inherent viscosity was 0.36dl/g All PES and MCM-22，49，56 were dried at 110°C for 12 h in a vacuum oven to remove the absorbed water.
All the materials shows platelets approximately 400–600 nm in length and 40-60 nm in thickness.
