摘要：

A concentration series of fluorite crystals Ca1-xSrxF2 (0 <= x <= 1) has been grown by directional crystallization according to the Bridgman technique. Experimental (weakly quadratic) concentration dependences of the lattice parameter a(x) and density rho(x) are obtained for the Ca1 - xSrxF2 (0 <= x <= 1) solid solution. A calibration density curve rho(x), which is suitable for non-destructive testing of the composition of optical elements made of Ca1 - xSrxF2 crystals with an error of Delta x = +/- 0.001, was constructed.
