Abstract

Cupric molybdate CuMoO4is an interesting material due to their rich electrical, optical and magnetic properties. In this work, Solid solutions CuMo(1-x)WxO4(x≤0.12) were obtained by pyrolysis at 400 -700°C for 2 hours of a polymeric precursors elaborated by polymerizable complex method. For x ≤ 0.075, they were isostructural with α-CuMoO4 and for 0.075<x≤0.12, they were isostructural with γ-CuMoO4. Spark Plasma Sintering (SPS) at 300°C for 5 min under an applied pressure of 200 MPa led to variety CuMoO4-III for tungsten contents in the range 0.075-0.12.
