摘要
采用氮气保护气氛下固相烧结法制备出Mn_3Ga_(0.503)Ge_(0.497)N化合物,并对其性能进行了测试。通过多晶粉末X射线衍射进行了结构表征和热膨胀性能测试,结果表明:具有立方反钙钛矿结构的Mn_3Ga_(0.503)Ge_(0.497)N化合物在420~470 K温度范围内表现出负热膨胀性能,其平均热膨胀系数为-13.3×10~(-6)K~(-1)。磁性测试结果表明:Mn_3Ga_(0.503)Ge_(0.497)N化合物在457 K左右发生了顺磁-铁磁的磁性转变。力学性能测试结果表明:其维氏硬度范围为450~480 HV,抗压强度和压缩弹性模量分别为350 MPa和2.48 GPa,是一种高硬度脆性陶瓷材料,可以用来制造具有轻质、刚性、低膨胀和高加工性的器件。
Mn_3Ga_(0.503)Ge_(0.497)N compound was prepared by solid state sintering under nitrogen atmosphere,and its properties were tested. The results of powder X-ray diffraction measurement for structure and thermal expansion performance show that the compound has cubic antiperovskite structure,furthermore,it exhibits the negative thermal expansion behavior at the temperature range of 420-470 K,with the average thermal expansion coefficient being-13. 3 × 10~(-6) K~(-1). The magnetic properties of Mn_3Ga_(0.503)Ge_(0.497)N were also measured by the physical property measurement system(PPMS),which show that the ferromagnetic(FM) to paramagnetic(PM) magnetic transition occurs around 457 K. The mechanical properties testing results show that the Vickers hardness range,the compressive strength and compressive modulus of the compound are 450-480 HV,350 MPa and 2. 48 GPa,respectively,which means that the compound is a kind of high hardness brittle ceramic material,and can be used to produce new materials with light weight,rigidity,low expansion and high workability.
