CASTING MOLD, CU-GA ALLOW SLAB, SPUTTERING TARGET, AND CU-GA ALLOY SLAB MANUFACTURING METHOD

摘要

The present invention provides a casting mold used when manufacturing Cu-Ga alloy slabs by a melting and casting method. A casting mold (100) includes a casting body (1) and a sloped member (2). The sloped member (2) has a sloped surface (21), wherein the more the sloped surface (21) extends inwards from an opening (11) of the casting body (1), the more said sloped surface (21) approaches the bottom surface (12) of the casting body (1). Between the edge (22) of the sloped member (2) and the inner circumferential surface of the casting body (1), a gap (G) is formed which is the opening through which an Cu-Ga alloy melt is poured into the casting body (1).
