In the present work, a series of scheelite‐related ( Li 0.5 Ln 0.5 ) MoO 4 ( Ln = Nd , Er , Gd , Y , Yb , Sm , and Ce ) ceramics were prepared by using the solid‐state reaction method. Except for the ( Li 0.5 Yb 0.5 ) MoO 4 , the other compositions were found to have a scheelite structure. Among all the compositions, the ( Li 0.5 Sm 0.5 ) MoO 4 , ( Li 0.5 Nd 0.5 ) MoO 4 , and ( Li 0.5 Ce 0.5 ) MoO 4 ceramics were found to possess low sintering temperatures below melting point of aluminum (660°C) and be chemically compatible with Al . The relation between microwave dielectric properties and structure was analyzed by using the Shannon additive rule and bond‐valence theory. This series of microwave dielectric ceramics might be candidate for low temperature co‐fired ceramics technology.
