These materials may perhaps be attributed to many variables including EPDD, IBLC, and secondaryphase particles. The LuNTO ceramics were ready by means of a Repotrectinib In Vitro solid-state reaction (SSR) approach. The highest dielectric performance exhibited by a LuNTO ceramic recorded a very high ‘ value of approximately 7.five 104 , while also exhibiting superb temperature stability among 60 C and 210 C and a very low tan value of approximately 0.007. The tan value exhibited at 200 C (approximately 0.05) was also acceptable. 2. Results and Discussion two.1. Crystal Structure and Phase Compositions Figure 1 shows the XRD patterns obtained in the LuNTO ceramics containing various co-dopant concentrations, ranging from 0.5.5 . The XRD spectra obtained from each of the LuNTO ceramics had been constant with those obtained from the most important phase of rutile TiO2, adopting a P42 /mnm space group, i.e., a tetragonal structure (JCPDS 21-1276) [33]. The lattice parameters (a and c values) are listed in Table 1. Owing for the larger ionic radii (r6) exhibited by the dopants (86.1 pm and 64.0 pm for Lu3 and Nb5 , respectively), the lattice parameters on the LuNTO ceramic have been larger than these ofMolecules 2021, 26, x FOR PEER REVIEW3 ofMolecules 2021, 26,rutile TiO2, adopting a P42/mnm space group, i.e., a tetragonal structure (JCPDS 211276) [33].

Owing towards the bigger ionic 15 3 of radii (r6) exhibited by the dopants (86.1 pm and 64.0 pm for Lu3 and Nb5, respectively), the lattice parameters in the LuNTO ceramic were larger than those of TiO2 (r6 (Ti4) = 60.5 pm). The a and c values in the LuNTO ceramics tended to enhance with growing co TiO2 (r6 (Ti4) = 60.five pm). and Nb5 c values with the LuNTO ceramics tended to enhance dopant concentration. The Lu3The a and dopant ions could either be partially or totally with growing co-dopant concentration. The Lu3 and Nb5 dopant ions could either substituted into the TiO2 structure. The impurity microwavedielectric phase, RENbTiO6 be partially or totally substituted in to the TiO2 structure. The impurity microwave-dielectric (RE = Lu), was observed inside the XRD spectra obtained from the LuNTO2 and LuNTO3 phase, RENbTiO6 (RE = Lu), was observed inside the XRD 7 impurity phase was also ob ceramics [34,35]. A modest Biotin Hydrazide In stock quantity of an more Lu2Ti2Ospectra obtained from the LuNTO2 and LuNTO-3 ceramics [34,35]. A modest quantity of an more Lu2 Ti2 O7 impurity served in the LuNTO3 ceramic [36]. These microwavedielectric phases ordinarily exhibit phase was also observed within the LuNTO-3 ceramic [36]. These microwave-dielectric phases a really low tan value and low conductivity [34,35,37,38].
