Abstract

We report here for the first time the temperature dependence of the electrical resistivity and heat capacity of nano-crystalline MgTiO3 geikielite of up to 1000 K. The temperature dependence of heat capacity of nano-crystalline geikielite expressed as Cp = 46.44(5) + 0.0502(2)T − 4.56 × 106T2 + 1.423 × 103T− 0.5 − 8.672 × 10− 6T− 2, where Cp = is specific heat expressed in J/mol. K and T is the temperature in K. Both the electrical resistivity and heat capacity behaviour show that the geikielite (both the natural and synthetic nano-crystalline samples) are stable and remains electrically insulating up to 1000 K.
