“…Compositions with different relative permittivity but about the same sintering temperature are in great demand for multilayer applications. A simple and useful approach to obtain material with desired properties is by composite approach, which is widely utilized for many applications [28][29][30][31][32][33][34][35][36][37][38][39][40][41][42].…”

The present paper presents ceramic composites with ultralow sintering temperature of 500 ̊C with densification of 96 % by adding small amount (0.5, 1 and 2 wt.%) of Ag2O to CuMoO4 by simple mixing method. The effect of Ag2O addition on the structure, microstructure, sintering and thermal as well as microwave dielectric properties of CuMoO4 is also studied. The reduction in the sintering temperature is due to the formation of trace amount (1.4%) of copper silver molybdate (Cu2Ag2(MoO4)3) as observed from Rietveld refinement analysis as well as backscattered SEM image. Doping has very little influence on the structure and coefficient of thermal expansion that is about 4.7-5.2 ppm/C. The composites sintered at 500 ̊C exhibit relative permittivity of about 8-9, quality factor (Qf) of 26000-37000 GHz at 12 GHz, temperature coefficient of resonant frequency of-31-33 ppm/C and are compatible with Al electrode. The present work results in obtaining welldensified ultralow temperature cofired ceramic composites at low sintering temperature without much structural change and good thermal properties but with different dielectric properties by small doping. These composites can be used as low cost candidates for wide range of microwave applications like multilayer packages and substrates owing to the low energy required during processing and hence can pave way to the advancement of electronic materials.

“…[109] Due to the nonpolar backbone, EPDM has low dielectric loss and generates little heat during actuation. [110] However, the dielectric constant of EPDM elastomer is relatively low. [15] Thus, it is necessary to incorporate high dielectric constant particles into it.…”

“…Ethylenepropylenediene monomer (EPDM) rubbers are commonly used as rubbery insulating materials for solid rocket engines [ 6 , 7 , 8 , 9 , 10 ]. EPDM rubbers are low-density synthetic polymers that have excellent mechanical properties and ablation resistances to a number of chemicals [ 11 , 12 , 13 , 14 ]. In addition, they exhibit excellent resistances to ozone, oxygen, heat and weathering degradation; however, they do not completely retard the migration of NG.…”

The triacetin and nitroglycerin barrier properties of layered-silicate reinforced ethylenepropylenediene monomer/chloroprene rubber (EPDM/CR) nanorubbers were investigated as rocket-propellant inhibitors. EPDM/CR nanorubbers with intercalated structures were formulated and prepared by the melt-compounding method. The triacetin permeability and nitroglycerin absorption were observed to decrease with increasing layered-silicate content. The layered silicates also improved the flame retardancies of the nanorubbers by forming silicate reinforced carbonaceous chars. Layered-silicate reinforced EPDM/CR nanorubbers are potentially effective rocket propellant-inhibiting materials.
