文摘The exploration of a large negative thermal expansion(NTE)over a wide temperature range has been an important subject in materials science,since the overall coefficient of thermal expansion(CTE)of ordinary materials can be effectively tailored by the introduction of NTE materials.Here,we successfully achieved a large NTE within a broad temperature range in a new Pb/Bi-based ferroelectric of(1−x)PbTiO_(3)–xBi(Zn_(1/2)V_(1/2))O_(3)by means of improving the ferroelectricity of PbTiO_(3).
