The effect of anisotropy on the mechanical properties was investigated for a chain‐structured metaphosphate glass (12.5Li 2 O–12.5Na 2 O–12.5K 2 O–12.5Cs 2 O–50P 2 O 5 mol%). Anisotropic glasses with different birefringence values were prepared with a fiber elongation method. The strength and Young's moduli of the glasses were measured with a three‐point bending method. It was found that the strength and Young's modulus increased with increasing birefringence, reaching about 160% and 140%, respectively, compared with the values for the isotropic glass. The enhancement of the mechanical properties was attributed to the orientation of ‐P‐O‐P‐ chains in the glass.
