Mechanical properties of ten sapphire ribbons are studied. These ribbons are grown simultaneously with prismatic orientation ( { 11 2 ¯ 0 } plane and ⟨ 1 ¯ 100 ⟩ direction) with the dimensions 2 × 85 × 400 mm. Strength and plastic characteristics of the crystals are determined on the as‐grown and mechanically treated surfaces. Peculiarities of the morphology and distribution of pores in thin subsurface layer are considered.
