Ba(Zn1/3Ta2/3)O3 ceramics reinforced high density polyethylene for microwave applications

Manu, K M; Soni, S; Murthy, V R K; Sebastian, M T (Springer, 2013)

The effect of Ba(Zn1/3Ta2/3)O3 (BZT) ceramic filler on the dielectric, mechanical and thermal properties of high density polyethylene (HDPE) matrix have been investigated. The dispersion of BZT particles in the matrix was ...
Crystal Structure and Microwave Dielectric Properties of LiRE9(SiO4)6O2 Ceramics (RE = La, Pr, Nd, Sm, Eu, Gd, and Er)

Manu, K M; Karthik, C; Leu, L C; Lazar, K A; Ubic, R; Sebastian, M T (Wiley, 2013)

The crystal structure and microwave dielectric properties of apatite-type LiRE9(SiO4)6O2 ceramics (RE = La, Pr, Nd, Sm, Eu, Gd, and Er) have been investigated. The densification of lithium apatites has been greatly improved ...
Effect of glass fluxing on densification and microwave dielectric properties of LiInSiO4 ceramic

Annrose, S; Lazer, K A; Manu, K M; Surendran, K P; Sebastian, M T (Elsevier, 2013)

A novel microwave substrate ceramic LiInSiO4 (LIS) was synthesized by solid-state ceramic route. LIS ceramic sintered at 1150 degrees C for 4 h showed a densification of 91% with epsilon(r) = 8.2, Q(u) x f = 12,600 GHz and ...
Electrical and thermal properties of low permittivity Sr2Al2SiO7 ceramic ﬁlled HDPE composites

Manu, K M; Ananthakumar, S; Sebastian, M T (Elsevier, 2013)

The feasibility of low permittivity Sr2Al2SiO7 (SAS) ceramic filled high density polyethylene (HDPE) composites for substrate and packaging applications has been investigated in this paper. The composites were prepared by ...
Low permittivity SrCuSi4O10-LMZBS glass composite for LTCC applications

Manu, K M; Anjana, P S; Sebastian, M T (Elsevier, 2011)

The tetragonal gillespite type SrCuSi4O10 (SCS) was prepared by the conventional solid-state ceramic route. The SCS sintered at 1100 degrees C/6 h showed epsilon(r) = 4.0 and tan delta =1.1 x 10(-3) at 5 GHz. The SCS has ...
Structure, microwave dielectric and optical properties of Ln(2/3)Gd(1/3)TiNbO(6) (Ln=Ce, Pr, Nd and Sm) ceramics

Annamma, J; Shyla Joseph; Manu, K M; Thomas, J K; Sam Solomon (Springer, 2011)

The Ln(2/3)Gd(1/3)TiNbO(6) ceramic compositions are prepared through the solid state ceramic route. The compositions are calcined at 1250 A degrees C and sintered in the range 1350-1435 A degrees C. Structural analysis of ...
Temperature compensated Sr2Al2SiO7 ceramic for microwave applications

Manu, K M; Tony Joseph; Sebastian, M T (Elsevier, 2012-03-15)

The Sr–Gehlenite (Sr2Al2SiO7) ceramic has been prepared by the conventional solid-state ceramic route.Phase pure Sr2Al2SiO7 (SAS) ceramic sintered at 1525 ◦C for 4 h has εr = 7.2 and Qu × f = 33,000 GHz. The SAS showed ...
