What are the properties of Quartz?
I'm assuming fused quartz linear thermal expansion clear fused silica/quartz 5.5×10-7/K 5.5×10-7/K x 14.5 cm x 170K = 1.36e-3 cm But that is linear expansion. Volume expansion would be 3 times that, or 4.07e-3 cm? edit other reference has 5.9 as the coefficient. .
