Abstract: An organic release agent is vacuum deposited over a substrate and surface treated with a plasma or ion-beam source in a gas rich in oxygen-based functional groups to harden a very thin layer of the surface of the deposited layer in passivating environment. Aluminum is subsequently vacuum deposited onto the hardened release layer to form a very flat and specular thin film. The film is exposed to a plasma gas containing oxygen or nitrogen to passivate its surface. The resulting product is separated from the substrate, crushed to break up the film into aluminum flakes, and mixed in a solvent to separate the still extractable release layer from the aluminum flakes. The surface treatment of the release layer greatly reduces wrinkles in the flakes, improving the optical characteristics of the flakes. The passivation of the flake material virtually eliminates subsequent corrosion from exposure to moisture.

Abstract: The purpose of the invention is to provide a sputtering target formed from a Cu—Ga alloy having a Ga composition of 29 at % or more. [Problem] Since a Cu—Ga alloy becomes a brittle ? phase-single phase structure when the Ga composition becomes 29 at % or more, it cannot be subject to processes such as rolling and forging. Accordingly, the crystal grain size of the cast structure must be small and uniform so that the cast structure can be used as is. [Solution] It is possible to produce a melted and cast Cu—Ga alloy sputtering target containing 29 to 42.6 at % of Ga, and remainder being Cu and unavoidable impurities by continuously solidifying the Cu—Ga alloy sputtering target under solidifying conditions of a constant cooling rate or higher, wherein an average crystal grain size of a sputter front face is 3 mm or less, and a cross section structure of the target is a columnar structure that has grown in a direction from the sputter front face toward a center plane which is parallel to a sputter face.

Abstract: The present invention includes a method for casting a silicon ingot by using a continuous casting method by means of an electromagnetic induction, and a method for cutting the silicon ingot as a starting material into plural silicon blocks. When the silicon blocks with a square section are cut out, the sectional shape of the silicon ingot is set to be rectangular. Not less than 6 pieces of equal-sized silicon blocks are cut out from the silicon ingot, thereby enabling to enhance the manufacturing efficiency to a great extent. And since the amount of excision of the edge per silicon block is reduced, the production yield can be enhanced. Further, since the proportion of columnar crystals with large grain size inside the ingot can be increased, it becomes possible to enhance the conversion efficiency of a solar battery using the silicon block as a substrate material.

Abstract: The production of steels with high contents of manganese (Mn), aluminum (Al), and silicon (Si) with TWIP properties (Twinning-Induced Plasticity) by continuous casting is considered difficult or impossible in the present state of the art for various reasons. These reasons include low strength of the strand shell during solidification due to intense microsegregation of Mn, high strength at relatively low temperatures, reactions of the aluminum in the steel with the flux powder, macrosegregation, depletion of the alloying elements near the surface, and oxidation of the grain boundaries during the reheating of slabs in the pusher furnace. Therefore, in accordance with the invention, successively arranged process steps are used to cast light gauge steel with a given chemical composition of 15-27% Mn, 1-6% Al, 1-6% Si, ?0.
