Abstract
CaF2 single crystals are interesting substrate materials for deposition of thin films. Its structure is cubic and it cleaves on 111 planes. CaF2, whose hardness has been reported to be 4 on the Moh’s scale, is plastic and soft. In this study, the mechanical properties such as hardness(H) and Young’s modulus(E) of single crystal CaF2 mineral were measured by using a nanoindenter with a Berkovich indenter normal to (100) and (111) planes. A normal indentation size effect (ISE) in accordance with the traditional power law and the proportional specimen resistance model (PSR) of Li and Bradt [1] was observed. The values of E and H on (100) plane are larger than those on (111) plane and these values on both planes decrease with increase in time during the hold segment. The effect of displacement rate on mechanical properties of (100) and (111) surfaces is also studied.
