Crucilble and method of growing single crytal by using crucible |
摘要 |
Provided are a crucible which prevents polycrystal formation to easily allow growth of optical part material single crystals, and a single crystal growth method employing the crucible. The crucible has a smooth surface of about Rmax 3.2s as the surface roughness of the wall surface 1 H, concave curved plane 1 J, cone surface 1 F and convex curved plane 1 L of the starting material carrying section 1 D and the wall surface 1 K of the seed carrying section 1 E, which constitute the inner surface of the crucible of a crucible body 1 A.
