Effect of Porosity and Grain Size on the Microwave Dielectric Properties of Sintered Alumina
S.J. Penn,Neil McN. Alford,Alan Templeton,Xiaoru Wang,Meishing Xu,Michael J. Reece,Kevin Schrapel +6 more
TL;DR: The real part of the permittivity and the tan δ of sintered polycrystalline alumina at about 9 GHz have been measured in this article, where the dielectric properties have been examined as a function of purity, pore volume, and sintering grain size.
Microwave Dielectric Loss of Titanium Oxide
TL;DR: The dielectric loss (tan δ) of titanium dioxide (TiO2) disks has been measured at a frequency of 3 GHz in this article, and the tan δ for all the high-Q doped TiO2 polycrystalline samples smoothly decrease to ∼5 × 10−6 (Q∼ 200 000) at 15 K, comparable to that of single crystals.

Dielectric loss caused by oxygen vacancies in titania ceramics
TL;DR: In this article, the microwave dielectric loss of undoped TiO2 was improved by annealing at 1500°C for 10h in air, presumably as a result of reoxidation.

Dielectric loss of oxide single crystals and polycrystalline analogues from 10 to 320 K
N McN Alford,Jonathan Breeze,Xiaoru Wang,S.J. Penn,Silvia Dalla,S.J. Webb,Neboysha Ljepojevic,Xavi Aupi +7 more
TL;DR: In this paper, the key factors influencing microwave dielectric loss are examined and a comparison is made between single crystals and polycrystalline analogues, for temperatures between 20 and 300 K.

Low Loss Sintered Dielectric Resonators with HTS Thick Films
TL;DR: In this paper, the authors show that at low temperatures the intrinsic loss is dominated by extrinsic losses due to crystal imperfection, residual dopant atoms, dislocations, and other lattice defects.
