Description
Summary:Investigations on the microstructural and electrical properties of a glassceramic system: (100 −  x ) [0.4Li 2 O − 0.1GeO 2  − 0.6P 2 O 5 ] +  x [20 h ball milled Ga 2 O 3 ] (0 ≤  x  ≤ 10 mol%, in the regular steps of 2 mol%) via high-energy ball milling technique are reported. XRD spectra of LGePG glassceramic samples were identified major crystalline phases such as Li 3 Ge 2 (PO 4 ) 3 (NASICON-type phase), Ga 2 Li 3 (PO 3 ) 7 and GeO 2 from the major diffraction peaks. Bulk conductivity of all these samples was measured for the powder-compressed pellets by ac impedance method. The correlation of log( σ ) and M ″ peaks suggests the presence of single conduction mechanism in the LGePG glassceramic samples. The results are discussed in the light of degree of crystallization of lithium phosphate glass network.
