Solid solutions Co 3-x Zn x TeO 6 (x = 0-3) were prepared both in polycrystalline and single-crystalline form using solid state reactions and chemical vapour transport reactions, respectively. Miscibility between the isotypic end members was established over the complete range (C2/c, Z = 12, a ≈ 14.85, b ≈ 8.83, c ≈ 10.34 Å, ≈ 93°). Crystal structure determinations, performed on basis of single crystal laboratory X-ray (at 295 K) and synchrotron (at 10 and 100 K) data of Co 3 TeO 6 and selected solid solutions, revealed no structural phase transition and allowed a detailed insight into the Co → Zn substitution mechanism. The coordination polyhedra of the five crystallographically independent M 2+ cations are distorted octahedra (for three cations), one distorted tetrahedron and one distorted square [a] Details of all crystal structure investigations can be obtained from Fachinformationszentrum Karlsruhe,
Transverse magnetic (TM) dielectric resonator filters are frequently affected by a poor contact in the interface between metal and ceramic walls, misalignment of the ceramic parts, and cracks due to mechanical stress. To overcome these issues, the present study proposes the development of monoblock filters fabricated by lithography‐based ceramic manufacturing. To build these structures with additive manufacturing, some geometrical changes, with respect to the classical assembly, have to be applied. The effect of these changes on the electrical performance of a stand‐alone resonator are studied. Then, a filter prototype is manufactured and measured to validate the feasibility of this approach.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
