Nickel Shows Ferromagnetic Property at Room Temperature
Nickel is particularly important because it's one of the few materials that display ferromagnetic properties at room temperature. This means that nickel can be used in applications where traditional magnets cannot, such as for making powerful electromagnets or creating permanent magnets with a long shelf life. Also, nickel can form alloys ...

Room-temperature synthesis of metal borides
According to a high-temperature Guinier experiment (Fig. 5), which was performed between room temperature and 900 °C, the primary product crystallizes as Ni 3 B at about 320 °C. When further heated very slowly, the sample alters and reflections of elemental Ni appear around 430 °C. At about 525 °C, Ni 3 B is no longer detected.
