Abstract
The deformation and fracture properties of synthetic α-quartz crystals were measured using hardness, pre-cracked bend and Hertzian tests over the range 20 to 545° C in air and dry nitrogen. The resistance to fracture decreases significantly with increase in temperature and is orientation-dependent (becoming very small as the inversion temperature is approached), while the microhardness remains relatively insensitive to temperature and environment. These effects are interpreted in terms of the moisture content of the environment and the intrinsic water content of the crystals.
