Table 2 shows the comparison of sintering temperature and microwave dielectric properties of low sintering binary ceramics with that of present work. It has been noted that, even with 88 % densification MoO3 possess moderately high Qf of 41000 GHz and low temperature coefficient of resonant frequency of -25 ppm/oC in comparison with other binary oxide reported. However, it should be noted that most of the molybdates have a strong reaction with Ag and Al, which limits their usage with the commonly used Ag and Al electrodes in LTCC/ULTCC applications [see supporting information Figure S1]. It has been reported that Ag2MoO4 and Al2 (MoO4)3 are the major intermediate compounds when MoO3 undergoes reaction with Ag and Al [56]. Still, the low temperature (≤ 200 oC) commercial electrode DuPont 8453 may be used as post firing applications for the present binary MoO3[57]. In addition to that, most of the reported molybdates [19-25] are water-soluble like reported H3BO3/B2O3 microwave ceramics [58]. It has been reported that the binary MoO3 water solubility is 0.490 g/100 mL (28 °C) in comparison with other ternary molybdates reported [59]. The importance of the present work is explore the excellent dielectric properties of the binary MoO3 ceramics. The reported results will be a suitable reference for the potential growth in the various applications of stable MoO3ceramics.
