Anti-perovskite manganese nitrides Mn3Zn0.6Ge0.4N with different crystallite size were prepared by spark plasma sintering (SPS) at different sintering temperatures. Their negative thermal expansion (NTE) properties were investigated. It was found that the width of NTE operation-temperature window (ΔT) broadens with decreasing crystallite size. Typically, a broad ΔTof 105 K was obtained in the compound Mn3Zn0.6Ge0.4N with average crystallite size of 54 nm sintered at 700 °C, of which the average linear thermal expansion coefficient was estimated to be −13.5 × 10−6K−1in the NTE operation-temperature window. This antiperovskite manganese nitride Mn3Zn0.6Ge0.4N with broadened ΔTaround room temperature is more useful for practical applications.
