Abstract
The production of low-loss, tunable composite ceramic materials with improved breakdown strengths is disclosed. The composite materials comprise ferroelectric perovskites such as barium strontium titanate or other ferroelectric perovskites combined with other phases such as low-loss silicate materials and/or other low-loss oxides. The composite materials are produced in sheet or tape form by methods such as tape casting. The composite tapes exhibit favorable tunability, low loss and tailorable dielectric properties, and can be used in various microwave devices.
Claims40
A method of making a layer of low-loss, tunable ceramic composite material with improved breakdown strength, the method comprising:
- tape casting a slurry comprising a mixture of at least one electronically tunable ceramic material and at least one additional ceramic material to form a tape cast layer;
- and
- sintering the tape cast layer.
A tape cast, low-loss, tunable ceramic composite layer having improved breakdown strength, the material comprising a sintered mixture of at least one tunable ceramic material and at least one additional ceramic material.
A multilayer laminated material with improved breakdown strength comprising at least one layer of a tape cast low-loss, tunable ceramic composite material.
